小鼠超氧化物歧化酶ELISA試劑盒操作步驟:
1. 使用前,將所有試劑充分混勻。不要使液體產(chǎn)生大量的泡沫,以免加樣時加入大量的氣泡,產(chǎn)生加樣上的誤差。
2. 根據(jù)待測樣品數(shù)量加上標(biāo)準(zhǔn)品的數(shù)量決定所需的板條數(shù)。每個標(biāo)準(zhǔn)品和空白孔建議做復(fù)孔。每個樣品根據(jù)自己的數(shù)量來定,能使用復(fù)孔的盡量做復(fù)孔。
3. 加入稀釋好后的標(biāo)準(zhǔn)品50ul于反應(yīng)孔、加入待測樣品50ul于反應(yīng)孔內(nèi)。立即加入50ul的生物素標(biāo)記的抗體。蓋上膜板,輕輕振蕩混勻,37℃溫育45分鐘。
4. 甩去孔內(nèi)液體,每孔加滿洗滌液,振蕩30秒,甩去洗滌液,用吸水紙拍干。重復(fù)此操作4次。如果用洗板機洗滌,洗滌次數(shù)增加一次。
5. 每孔加入100ul的親和鏈酶素-HRP,輕輕振蕩混勻,37℃溫育30分鐘。
6. 甩去孔內(nèi)液體,每孔加滿洗滌液,振蕩30秒,甩去洗滌液,用吸水紙拍干。重復(fù)此操作4次。如果用洗板機洗滌,洗滌次數(shù)增加一次。
7. 每孔加入底物A、B各50ul,輕輕振蕩混勻,37℃溫育5分鐘。避免光照。
8. 取出酶標(biāo)板,迅速加入50ul終止液,加入終止液后應(yīng)立即測定結(jié)果。
9. 在450nm波長處測定各孔的OD值。
Assay procedure
1.Dilute and add sample:Dilute Original density Standard as follow table:
20μg/L5 Standard150μl Original density Standard+150μl Standard diluent
10μg/L4 Standard150μl 5 Standard+150μl Standard diluent
5μg/L3 Standard150μl 4 Standard+150μl Standard diluent
2.5μg/L2 Standard150μl 3 Standard +150μl Standard diluent
1.25μg/L1 Standard150μl 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 30 min at 37℃.
4.Configurate liquid: 30-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 to each well, evade the light preservation for 15 min at 37℃
10.Stop the reaction:Add Stop Solution50μl to each well, Stop the reaction(the blue color change to yellow color).
