FOR RESEARCH USE ONLY
Assay range:5ng/L - 180ng/L 96 determinations
Purpose
This kit allows for the determination of DAG1 concentrations in Human serum, cell culture supernates and other biological fluids
Principle of the assay
The kit assay Human DAG1 level in the sample, use Purified Human DAG1 antibody to coat microtiter plate wells, make solid-phase antibody, then add DAG1 to wells, Combined DAG1 antibody which With HRP labeled, become antibody - antigen - enzyme-antibody complex, after washing Compley, Add TMB substrate solution,TMB substrate becomes blue color At HRP enzyme-catalyzed, reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. The concentration of Human DAG1 in the samples is then determined by comparing the O.D. of the samples to the standard curve.

2. Add sample: Set blank wells separay (blank comparison wells don’t add sample and HRP-Conjugate reagent, other each step operation is same). testing sample well. add standard 50μl in the Microelisa stripplate accuray,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 30 min 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 by pat.
6. Add enzyme: Add HRP-Conjugate reagent 50μl to each well, except blank well.
7. Incubate: Operation with 3.
8. Washing: Operation with 5.
9. Color: Add Chromogen Solution A 50ul and Chromogen Solution B 50ul 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.

Calculate
Take the standard density as the horizontal, the OD value for the vertical ,draw the standard curve on graph paper, Find out the corresponding density according to the sample OD value by the Sample curve, multiplied by the dilution multiple, or calculate the straight line regression equation of the standard curve with the standard density and the OD value ,with the sample OD value in the equation, calculate the sample density, multiplied by the dilution factor, the result is the sample actual density.
