产品简介
Elabscience公司最新推出的二步法免疫组化试剂盒,将二抗的单价 Fab 片段和过氧化物酶HRP聚合在一起,替代传统方法中的二抗和三抗,直接放大抗原抗体结合的信号,既保留了抗体特异性结合抗原的能力,又可有效地避免聚合分子过大而 造成的空间位阻。与传统的 SP 三步法相比,此试剂盒具有简单、快速、敏感等特点,试剂盒不再使用生物素,避免了由于内源性生物素所造成的背景染色。本产品可用于检测一抗是Rabbit和Mouse来源的单克隆抗体或多克隆抗体。
附带的DAB显色液自带稀释液,避免由于各地方水酸碱度的不同对 DAB 显色所造成的影响。

使用说明
1. 脱蜡、水化组织切片。
2. 根据抗原抗体情况,必要时对切片进行抗原热修复或消化处理。
3. 滴加E-IR-R217C(3% H2O2),室温10分钟以灭活内源性酶。PBS清洗,3分钟×3次。
4. 滴加E-IR-R217A(正常山羊血清),37°C封闭30分钟。甩去多余液体。
5. 滴加适当稀释的一抗(兔或小鼠 IgG),20~37°C 1~2小时或4°C过夜。PBS洗3分钟×3次,吸水纸擦干切片。
6. 滴加E-IR-R217B( Polyperoxidase-anti-Mouse/Rabbit IgG),37°C孵育30分钟,PBS或TBS冲洗,3分钟×3次。
7. 每1 mL E-IR-R217E(DAB底物液)中,加入1滴(约50 μL)的E-IR-R217D (DAB浓缩液)。混合均匀,即配成DAB工作液。此溶液必须现配现用,配好后避光保存。4小时内使用,剩余的液体舍弃。
8. 控制好DAB显色时间,阳性信号为棕黄色或褐黄色,切勿显色过深。
9. 蒸馏水冲洗切片终止显色后复染、脱水、透明、封片。
保存条件
2~8°C避光保存,不得冻存,有效期12个月。开封使用后,请在6个月内用完。
