背景介绍
HER2, also known as ErbB2 and Neu, is a 185-kDa transmembrane glycoprotein that is a member of the epidermal growth factor(EGF) receptor family of receptor tyrosine kinases. It has no ligand binding domain of its own and therefore cannot bind growth factors. However, it does bind tightly to other ligand-bound EGF receptor family members to form a heterodimer, stabilizing ligand binding and enhancing kinase-mediated activation of downstream signalling pathways, such as those involving mitogen-activated protein kinase and phosphatidylinositol-3 kinase. Amplification and/or overexpression of HER2 have been reported in numerous cancers, including breast and ovarian tumors. HER2 is a therapeutic target for the treatment of breast cancer and other carcinomas. This antibody raised against a synthesized peptide corresponding to 1237-1255aa of human HER2 recognizes the 185-kDa full-length glycosylated form and other lower molecular-mass forms of HER2, including the truncated form.
抗体可以回收利用几次?

一般抗体不推荐回收利用,抗体使用之后缓冲体系已经发生改变,不同客户在回收抗体的保存条件上也会有差异,所以抗体回收使用效果无法保证。

FineTest公司也做过一批抗体回收验证测试,测试结果显示不同抗体可回收次数不同,一般效价越高的抗体,可重复使用的次数越多,客户可根据实验情况来确定。

注:我们将孵育完毕后剩余的抗体回收到离心管中置于4℃保存,效价高的抗体可至少保存1周,重复利用3次左右。

FineTest公司抗体buffer成分是什么?

FineTest抗体成分一般是PBS含proclin300或sodium azide、BSA、50%甘油;也有一些是PBS含proclin300或sodium azide,50%甘油。防腐剂proclin300或sodium azide是常用的防腐剂,广泛应用于实验室和工业中。

FineTest公司抗体的保存温度和时间?

大部分抗体是放在-20℃保存,直标流式抗体需要放在2-8℃保存,质保期一年,质保期内抗体出现售后,可进行退货或换货。

一般抗体超过一年质保期仍旧可以使用,我们可以提供技术支持服务。

FineTest公司抗体使用需要稀释吗?用什么溶液稀释?

除了直标流式抗体为即用型,不用稀释。其他抗体一般为浓缩型,使用时需要按照说明书建议稀释比例稀释。

不同实验使用的稀释液不同,用PBST, TBST, 抗体封闭液等常用抗体稀释液均可。

免疫组化实验抗体的修复方式?

常用修复液:Tris-EDTA缓冲液(Tris-EDTA Buffer, pH 9.0);柠檬酸盐缓冲液(Citrate Buffer, pH 6.0)

热修复:

方法1:沸水浴修复,将盛有修复液和玻片的烧杯置于沸水浴环境,保持外部沸腾状态15min,自然冷却至室温;

方法2:微波修复,将盛有修复液和玻片的烧杯置于微波炉中,高火5min,停火3min,中火5min,自然冷却至室温。

如何选择二抗?

(1)二抗是和一抗反应的,所以二抗必须是抗一抗宿主物种,比如一抗来源于兔,对应二抗则选择抗兔二抗,比如羊抗兔或驴抗兔。

(2)根据实验类型选择二抗偶联物,比如做ELISA, 蛋白质印迹,IHC实验,常用酶联二抗,如HRP,AP等标记。而免疫荧光实验,流式细胞术实验中,则用荧光蛋白或染料标记,比如FITC,Cy3等。
