背景介绍
Saposin-A and saposin-C stimulate the hydrolysis of glucosylceramide by beta-glucosylceramidase(EC 3.2.1.45) and galactosylceramide by beta-galactosylceramidase(EC 3.2.1.46). Saposin-C apparently acts by combining with the enzyme and acidic lipid to form an activated complex, rather than by solubilizing the substrate.Saposin-B stimulates the hydrolysis of galacto-cerebroside sulfate by arylsulfatase A(EC 3.1.6.8), GM1 gangliosides by beta-galactosidase(EC 3.2.1.23) and globotriaosylceramide by alpha-galactosidase A(EC 3.2.1.22). Saposin-B forms a solubilizing complex with the substrates of the sphingolipid hydrolases. Saposin-D is a specific sphingomyelin phosphodiesterase activator(EC 3.1.4.12). Prosaposin: Behaves as a myelinotrophic and neurotrophic factor, these effects are mediated by its G-protein-coupled receptors, GPR37 and GPR37L1, undergoing ligand-mediated internalization followed by ERK phosphorylation signaling. Saposins are specific low-molecular mass non-enzymic proteins, they participate in the lysosomal degradation of sphingolipids, which takes place by the sequential action of specific hydrolases.
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。
