Important notes(注意事項):
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.
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, if the number of sample is much , recommend to use Volley .
4.if the testing material content is excessively higher (The sample OD is bigger than the first standard well ),please dilute Sample (n-fold), Please diluente 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.
7.Please according to use instruction strictly, The test result determination must take the microtiter plate reader as a standard.
8.All samples, washing buffer and each kind of reject should according to infective material process.
9.Do not mix reagents with those from other lots.
ELISA原理
ELISA是以免疫學反應為基礎,將抗原、牽9體的特異性反應與酶對底物的高效催化作用相結合起來的一種敏感性很高的試驗技術。由于抗原、抗體的反應在一種固相載體──聚苯乙烯微量滴定板的孔中進行,每加入一種試劑孵育后,可通過洗滌除去多余的游離反應物,從而保證試驗結果的特異性與穩定性。在實際應用中,通過不同的設計,具體的方法步驟可有多種。即:用于檢測抗體的間接法(圖a)、用于檢測抗原的雙抗體夾心法(圖b)以及用于檢測小分子抗原或半抗原的抗原競爭法等等。比較常用的是ELISA雙抗體夾心法及ELISA間接法。
樣品采集:
收集標本前必須清楚要檢測的成份是否足夠穩定。對收集后當天進行檢測的標本,儲存在4℃備用,如有特殊原因需要周期收集標本,將標本及時分裝后放在-20℃或-70℃條件下保存。避免反復凍融。標本2-8℃可保存48小時,-20℃可保存1個月。-70度可保存6個月。部分激素類標本需添加抑肽酶。
