Assay procedure
1.Dilute and add sample to Standard: set 10 Standard wells on the ELISA plates coated, add
Standard 100μl to the first and the second well, then add Standard dilution 50μl to the first and
the second well, mix; take out 100μl form the first and the second well then add it to the third
and the forth well separately. then add Standard dilution 50μl to the third and the forth
well ,mix ; then take out 50μl from the third and the forth well discard, add 50μl to the fifth and
4
the sixth well ,then add Standard dilution 50μl to the fifth and the sixth well, mix ; take out 50μl
from the fifth and the sixth well and add to the seventh and the eighth well, then add Standard
dilution 50μl to the seventh and the eighth well ,mix ; take out 50μl from the seventh and the
eighth well and add to the ninth and the tenth well, add Standard dilution 50μl to the ninth and
the tenth well, mix , take out 50μl from the ninth and the tenth well discard(add Sample 50μl to
each well after Diluting ,(density: 3000ng/L,2000ng/L ,1000ng/L,500 ng/L, 250ng/L)
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 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.
