产品描述

                                                       猪白介素1β (IL-1β)ELISA试剂盒
Assay range:1 ng/L -45ng/L 96 determinations
Purpose
This kit allows for the determination of IL-1 β concentrations inPorcine serum, cell culture supernates and other biological fluids
Principle of the assay
The kit assay Porcine IL-1β level in the sample,use Purified Porcine IL-1β antibody to coat microtiter plate wells, make solid-phase antibody, then addIL-1 β to wells, Combined IL-1β antibody which With HRP labeled,becomeantibody - antigen - enzyme-antibody complex, after washing Completely, AddTMB substrate solution,TMB substrate becomes blue color At HRPenzyme-catalyzed, reaction is terminated by the addition of a sulphuric acidsolution and the color change is measured spectrophotometrically at awavelength of 450 nm. The concentration of Porcine IL-1β in the samples isthen determined by comparing the O.D. of the samples to the standard curve.

Specimen requirements
1. extract as soon as possible after Specimen collection,and according to therelevant literature, and should be experiment as soon as possible after theextraction. If it can’t, specimen can be kept in -20 ℃ to preserve, Avoidrepeated freeze-thaw cycles.
2. Can’t detect the sample which contain NaN3, because NaN3 inhibits HRPactive.
Assay procedure
1. Dilute and add sample:Dilute Original density Standard as follow table:
40ng/L 5 Standard 150μl Original density Standard+150μl Standard diluent
20ng/L 4 Standard 150μl 5 Standard+150μl Standard diluent
10ng/L 3 Standard 150μl 4 Standard+150μl Standard diluent
5ng/L 2 Standard 150μl 3 Standard +150μl Standard diluent
2.5ng/L 1 Standard 150μl 2 Standard +150μl Standard diluent
2.add sample:Set blank wells separately (blank comparison wells don’t add
sample and HRP-Conjugate reagent, other each step operation is same).
testing sample well. add Sample dilution 40μl to testing sample well, then add
testing sample 10μl (sample final dilution is 5-fold), add sample to wells ,
don’t touch the well wall as far as possible, and Gently mix.
3.Incubate: After closing plate with Closure plate membrane ,incubate for 30min at 37℃.
4.Configurate liquid: 30-fold(or 20-fold) wash solution diluted 30-fold (or 20-fold)with distilled water and reserve.
5.washing:Uncover Closure plate membrane, discard Liquid, dry by swing,add washing buffer to every well, still for 30s then drain, repeat 5 times, dry bypat.
6.add enzyme:Add HRP-Conjugate reagent 50μl to each well, except blank3well.
7.incubate:Operation with 3.
8.washing:Operation with 5.
9.color:Add Chromogen Solution A 50ul and Chromogen Solution B to each
well, evade the light preservation for 10 min at 37℃
10.Stop the reaction:Add Stop Solution50μl to each well, Stop the reaction(the
blue color change to yellow color).
11.assay:take blank well as zero , Read absorbance at 450nm after Adding
Stop Solution and within 15min.
Steps description
Standard, Sample diluent
Add Standard, Sample diluent, incubate for 30 min at 37℃.
Wash 5 time,Add HRP-Conjugate reagent, incubate for 30 min at 37℃.
Wash 5 times,Add Chromogen Solution A and B, incubate for 10 min at 37℃.Add Stop Solution4Read absorbance at 450nm within 15 min
calculate
Calculate
Take the standard density as the horizontal, the OD value for thevertical ,draw the standard curve on graph paper, Find out the correspondingdensity according to the sample OD value by the Sample curve, multiplied bythe dilution multiple, or calculate the straight line regression equation of thestandard curve with the standard density and the OD value ,with the sampleOD value in the equation, calculate the sample density, multiplied by thedilution factor, the result is the sample actual density.
Important notes
1. The kit takes out from the refrigeration environment should be balanced15-30 minutes in the room temperature, ELISA plates coated if has not useup after opened, the plate should be stored in Sealed bag.
2. washing buffer will Crystallization separation, it can be heated the waterhelps dissolve when dilute . Washing does not affect the result.
3. add Sample with sampler Each step, And proofread its accuracy frequently,avoids the experimental error. add sample within 5 min, if the number ofsample is much , recommend to use Volley .
4. if the testing material content is excessively higher (The sample OD isbigger than the first standard well ),please dilute Sample (n-fold), Pleasediluente and multiplied by the dilution factor.(×n×5).
5. Closure plate membrane only limits the disposable use, to avoidcross-contamination.
6. The substrate evade the light preservation.
7. Please according to use instruction strictly, The test result determination5must take the microtiter plate reader as a standard.
8. All samples, washing buffer and each kind of reject should according toinfective material process.
9. Do not mix reagents with those from other lots.
Storage and validity
1.Storage: 2-8℃.
2.validity: six months
