CSB-E04488h人環(huán)磷酸腺苷(cAMP)ELISA Kit

1Human cyclic adenosinemonophosphate(cAMP)Elisa KitCatalog No. CSB-E04488h(96T) This immunoassay kit allows for the in vitro quantitative determination of humancAMP concentrations in serum, plasma. Expiration date six months from the date of manufacture FOR RESEARCH USE ONLY. NOT FOR USE IN DIAGNOSTIC PROCEDURES.2INTRODUCTIONCyclic adenosine monophosphate (cAMP, cyclic AMP or 3'-5'-cyclicadenosine monophosphate) is a second messenger important in manybiological processes. cAMP is derived from adenosine triphosphate (ATP)and used for intracellular signal transduction in many different organisms,conveying the cAMP-dependent pathway.cAMP is synthesised from ATP by adenylyl cyclase located on the innerside of the plasma membrane. Adenylyl cyclase is activated by a range ofsignaling molecules through the activation of adenylyl cyclase stimulatory G(Gs)-protein-coupled receptors and inhibited by agonists of adenylylcyclase inhibitory G (Gi)-protein-coupled receptors. Liver adenylyl cyclaseresponds more strongly to glucagon, and muscle adenylyl cyclase respondsmore strongly to adrenaline.cAMP decomposition into AMP is catalyzed by the enzymephosphodiesterase.cAMP is a second messenger, used for intracellular signal transduction,such as transferring the effects of hormones like glucagon and adrenaline,which cannot pass through the cell membrane. It is involved in theactivation of protein kinases and regulates the effects of adrenaline andglucagon. It also regulates the passage of Ca2+ through ion channels.3PRINCIPLE OF THE ASSAYThe microtiter plate provided in this kit has been pre-coated with agoat-anti-mouse IgG. Standards or samples are then added to theappropriate microtiter plate wells with a HRP-conjugated cAMP andantibody preparation specific for cAMP and incubated. Then substratesolutions are added to each well. The enzyme-substrate reaction isterminated by the addition of a sulphuric acid solution and the color changeis measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. Theconcentration of cAMP in the samples is then determined by comparing theO.D. of the samples to the standard curve.DETECTION RANGE0.08pmol/ml-250 pmol/ml. The standard curve concentrations used for theELISA’s were 250 pmol/ml, 50 pmol/ml, 10 pmol/ml, 2 pmol/ml, 0.4 pmol/ml,0.08 pmol/ml.SPECIFICITYThis assay recognizes human cAMP No significant cross-reactivity orinterference was observed.4MATERIALS PROVIDEDReagent QuantityAssay plate 1Standard1 x 0.25 ml(5000pmol/ml)HRP-conjugate 1(1000 x stock solution)Antibody 1(1000 x stock solution)HRP-conjugate Diluent 1 x 6 mlAntibody Diluent 1 x 6 mlNeutralizing Reagent 1 x 6 mlWash Buffer1 x 15 ml(10×concentrate)Substrate A 1 x 10 mlSubstrate B 1 x 10 mlStop Solution 1 x 6 mlOTHER SUPPLIES REQUIRED1. Deionized or distilled water.2. Concentrated HCl.3. Precision Pipets for volumes between 5μ l and 1000μ l.4. Repeater Pipets for dispensing 50μ l and 200μ l.5. Disposable breakers for diluting buffer concentrates.6. Graduated cylinders.7. A microplate shaker.8. Adsorbent paper for blotting.9. Microplate reader capable of reading at 450 nm, preferably withcorrection between 570 and 590 nm.5STORAGE1. For long-term best results, store stocks of the Standard ,Antibody andHRP-conjugate at -80℃. All other components of this kit are stable at4°C until the kit's expiration date.SAMPLE COLLECTION AND STORAGEThis ELISA is compatible with cAMP samples that have been treated withhydrochloric acid to stop endogenous phosphodiesterase activity. Samplesin this matrix can be measured directly without evaporation or furthertreatment.Tissue samples should be frozen in liquid nitrogen. The tissue should beground to a fine powder under liquid nitrogen in a stainless steel mortar.After the liquid nitrogen has evaporated, weigh the frozen tissue andhomogenize in 10 volumes of 0.1M HCl. Centrifuge at > 600 x g at roomtemperature. The samples can then be diluted in the 0.1M HCl.Cells grown in tissue culture media can be treated with 0.1M HCl after firstremoving the media. Incubate for 10 minutes and visually inspect the cellsto verify cell lysis. If adequate lysis has not occurred incubate for a further10 minutes and inspect. Centrifuge at 600 x g at room temperature, thenuse the supernatant directly in the assay. Cell or tissue lysis can beenhanced by adding 0.1% to 1% Triton x-100 to the 0.1M HCl prior to use.When used in this concentration range, the detergent will not interfere with6the binding portion of the assay, however there will be a modest increase inthe optical density. Samples containing Triton should be evaluated against astandard curve diluted in the same for the most accurate determination.Cyclic AMP in the media can be measured after treating 1 mL of thesupernatant media with 10 μ L of concentrated hydrochloric acid.Centrifuge at 600 x g at room temperature. The supernatants can then beused directly in the assay.Procedural Notes1. Allow all reagents to warm to room temperature for at least 30 minutesbefore opening.2. Pre-rinse the pipet tip with reagent ,use fresh pipet tips for eachsample,standard and reagent.3. Pipet standards and samples to the bottom of the wells.4. Add the reagents to the side of the well to avoid contamination.5. The kit uses break-apart microtiter strips,which allow the user tomeasure as many samples as desired.Unused wells must be keptdesiccated at 4℃ in the sealed bag provided,The wells should be usedin the frame provided.6. Prior to addition of substrate ensure that there is no residual washbuffer in the wells .Any remaining wash buffer may cause variationin assay resultes.REAGENT PREPARATIONBring all reagents to room temperature before use.71. Wash Buffer If crystals have formed in the concentrate, warm to roomtemperature and mix gently until the crystals have completely dissolved.Dilute 15 ml of Wash Buffer Concentrate into deionized to prepare 150ml of Wash Buffer.2. HRP-conjugate working solution: Centrifuge the vial right before use.Dilute the HRP-conjugate 1000x stock solution (take 6μl) with theprovided dilution buffers (6 ml).3. Antibody working solution: Centrifuge the vial right before use. Dilutethe Antibody 1000x stock solution (take 6μl) with the provided dilutionbuffers (6 ml).4. Standards: Centrifuge the vial right before use. Allow the 5,000pmol/mL cAMP standard solution to warm to room temperature. Labelsix tubes #1 through #6. Pipet 475 μL 0.1M HCl into tube #1 and 400 μL0.1M HCl into tubes #2-6. Add 25 μL of the 5,000 pmol/mL standard totube #1. Vortex thoroughly. Add 100 μL of tube #1 to tube #2 andvortex thoroughly. Continue this for tubes #3 through #6. Theconcentration of cAMP in tubes #1 through #6 will be 250, 50, 10, 2, 0.4,and 0.08 pmol/mL respectively. Diluted standards should be usedwithin 30 minutes of preparation. Label one tube as the ZeroStandard/NSB tube. Pipet 600μl 0.1M HCl into this tube.ASSAY PROCEDUREBring all reagents to room temperature for at least 30 minutes prioropening.ALL standards and samples should be run in duplicate.Add the reagen directly to the samples and vortex for 2 seconds immediatelyafter the addition.81. Refer to the Assay Layout Sheet to determine the number of wells to beused and put any remaining wells with the desiccant back into thepouch and seal the ziploc .Store unused wells at 4℃.2. Pipet 50 μL of the Neutralizing Reagent into each well, except theTA(Total Activity) and Blank wells.3. Pipet 100 μL of 0.1M HCl into the NSB(None Specific Binding) and theBo (0 pmol/mL Standard) wells.4. Pipet 100 μL of Standards into the appropriate wells.5. Pipet 100 μL of the Samples into the appropriate wells.6. Pipet 50 μL of 0.1 M HCl into the NSB wells.7. Pipet 50 μL of HRP-conjugate working solution into each well exceptthe TA and Blank wells.8. Pipet 50 μL of Antibody working solution into each well, except theBlank, TA and NSB wells.9. Incubate the plate at room temperature for 2 hours on a plate shaker at250~500 rpm.10. Empty the contents of the wells and wash by adding 400 μL of washsolution to every well. Repeat the wash 2 more times for a total of 3washes.11. After the final wash, empty or aspirate the wells, and firmly tap the plateon a lint free paper towel to remove any remaining wash buffer.12. Add 5 μL of the HRP-conjugate working solution to the TA wells.913. Add 200 μL of the Substrate solution to every well. Incubate at roomtemperature for 5~30 minutes without shaking. A gradient of blue colorshould become visible during the incubation period. (Substrate A andB should be mixed together in equal volumes within 15 minutes ofuse. Protect from light.)14. Add 50 μL of Stop Solution to every well. This stops the reaction andthe plate should be read immediately.15. Blank the plate reader against the Blank wells, read the optical densityat 450 nm (for HRP), preferably with correction between 570 and 590nm. If the plate reader is not able to be blanked against the Blankwells, manually subtract the mean optical density of the Blank wellsfrom all readings.1 0CALCULATION OF RESULTSSeveral options are available for the calculation of the concentration ofcAMP in the samples. The X-axis is the concentration of cAMP for thestandards. The Y-axis is either the Average Net Optical Density or thePercent Bound.1. Calculate the average Net Optical Density (OD) bound for each standardand sample by subtracting the average NSB OD from the average ODbound:Average Net OD = Average Bound OD - Average NSB OD2. Calculate the binding of each pair of standard wells as a percentage ofthe maximum binding wells (Bo), using the following formula:3. Using Logit-Log paper plot Average Net OD or Percent Bound(B/Bo) versus concentration of cAMP for the standards. Theconcentration of cAMP in the unknowns can be determined byinterpolation.1 1Typical Standard CurvesThese curves must not be used to calculate cAMP concentrations; eachuser must run a standard curve for each assay and version used.SensitivitySensitivity was calculated by determining the average optical density boundfor ten wells run with the Bo, and comparing to the average optical densityfor ten wells run with Standard #5. The detection limit was determined asthe concentration of cAMP measured at two standard deviations from thezero along the standard curve.Non-Acetylated VersionMean OD for Bo = 0.685±0.003Mean OD for Standard #5 = 0.604±0.010Delta Optical Density(0-0.08pmol/ml) = 0.0812 SD's of the Zero Standard = 0.006Sensitivity = ̄0.006/0.081×0.4pmol/ml = 29.6 fmol/mL1 2LinearityA sample containing 16.0 pmol/mL cAMP was serially diluted 7 times 1:2 inthe 0.1M HCl and measured. The data was plotted graphically as actualcAMP concentration versus measured cAMP concentration. The lineobtained had a slope of 1.000 with a correlation coefficient of 0.999.Cross ReactivitiesThe cross reactivities for a number of related compounds were determinedby competition ELISA assays. Potential cross reactants were dissolved inthe kit Assay Buffer at concentrations from 500,000 to 500 pmol/mL. Thesesampleswere then measured in the cAMP assay, and the measured cAMPconcentration at 50% B/Bo calculated. The % cross reactivity wascalculated by comparison with the actual concentration of cross reactant inthe sample and expressed as a percentage.Compound Cross ReactivitycAMP 100%AMP <0.0001%ATP <0.0001%cGMP <0.0001%GMP <0.0001%GTP <0.0001%cUMP <0.0001%CTP <0.0001%
