重復(fù) 5 次,拍干。
6. 加酶:每孔加入酶標(biāo)試劑 50 μ l ,空白孔除外 。
7. 溫育:操作同 3 。
8. 洗滌:操作同 5 。
9. 顯色:每孔先加入顯色劑 A50 μ l ,再加入顯色劑 B50 μ l ,輕輕震蕩混勻, 37 ℃ 避光顯 色
15 分鐘 .
10. 終止:每孔加終止 液 50 μ l ,終止反應(yīng) (此時(shí)藍(lán)色立轉(zhuǎn)黃色 ) 。
11. 測(cè)定 : 以空白空調(diào)零 , 4 50 nm 波長(zhǎng)依序測(cè)量各孔的 吸光 度 ( OD 值 ) 。 測(cè)定應(yīng)在加終止
液后 15 分鐘以?xún)?nèi)進(jìn)行。
注意事項(xiàng):
1 . 試劑盒從冷藏環(huán)境中取出應(yīng)在室溫平衡 15-30 分鐘后方可使用,酶標(biāo)包被板開(kāi)封后如未
用完,板條應(yīng)裝入密封袋中保存。
2 . 濃洗滌液 可能 會(huì)有 結(jié)晶 析出,稀釋時(shí)可在水浴中加溫助溶 ,洗滌時(shí)不影響結(jié)果。
3 . 各步加樣均應(yīng)使用加樣器 , 并經(jīng)常校對(duì)其準(zhǔn)確性 , 以避免試驗(yàn)誤差 。 一次加樣時(shí)間
控制在 5 分鐘內(nèi),如標(biāo)本數(shù)量多,使用排槍加樣。
4 . 請(qǐng)每次測(cè)定的同時(shí)做標(biāo)準(zhǔn)曲線(xiàn) , 做復(fù)孔 。 如標(biāo)本中待測(cè)物質(zhì)含量過(guò)高 ( 樣本 OD 值
大于標(biāo)準(zhǔn)品孔*孔的 OD 值 ) ,請(qǐng)先用樣品稀釋液稀釋一定倍數(shù)( n 倍)后再測(cè)定 , 計(jì)
算時(shí)請(qǐng)zui后 乘以 總稀釋倍數(shù)( × n × 5 ) 。
5 . 封板膜只限一次性使用,以避免交叉污染。3
6 . 底物請(qǐng)避光保存。
7 . 嚴(yán)格按照說(shuō)明書(shū)的操作進(jìn)行,試驗(yàn)結(jié)果判定必須以酶標(biāo)儀讀數(shù)為準(zhǔn) .
8 . 所有樣品,洗滌液和各種廢棄物都應(yīng)按傳染物處理。
9 . 本試劑不同批號(hào)組分不得混用。
10. 如與英文說(shuō)明書(shū)有異,以英文說(shuō)明書(shū)為準(zhǔn)。
計(jì)算 :
以標(biāo)準(zhǔn)物的濃度為橫坐標(biāo), OD 值為縱坐標(biāo),
在坐標(biāo)紙上繪出標(biāo)準(zhǔn)曲線(xiàn),根據(jù)樣品的 OD
值由標(biāo)準(zhǔn)曲線(xiàn)查出相應(yīng)的濃度;再乘以 稀釋
倍數(shù) ;或用標(biāo)準(zhǔn)物的濃度與 OD 值計(jì)算出標(biāo)
準(zhǔn)曲線(xiàn)的直線(xiàn)回歸方程式,將樣品的 OD 值
代入方程式,計(jì)算出樣品濃度,再乘以 稀釋
倍數(shù) ,即為樣品的實(shí)際濃度。

Important Important Important Important notes notes notes notes
1. The kit takes out from the refrigeration environment should be balanced
15-30 minutes in the room temperature, ELISA plates coated if has not use
up after opened, the plate should be stored in Sealed bag.8
2. washing buffer will Crystallization separation, it can be heated the water
helps 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 s , if the number of
sample is much , recommend to use Volley .
4. if the testing material content is excessively high er (The sample OD is
bigger than the first standard well ),please dilute Sample (n -fold ), Please
diluent e and multiplied by the dilution factor . ( × n × 5 ) .
5. Closure plate membrane only limits the disposable use, to avoid
cross-contamination .
6. The substrate evade the light preservation . . . .
