- 背景介绍
- Acts as NAD-dependent protein lipoamidase, ADP-ribosyl transferase and deacetylase(PubMed:19220062). Catalyzes more efficiently removal of lipoyl-and biotinyl-than acetyl-lysine modifications. Inhibits the pyruvate dehydrogenase complex(PDH) activity via the enzymatic hydrolysis of the lipoamide cofactor from the E2 component, DLAT, in a phosphorylation-independent manner(PubMed:25525879). Catalyzes the transfer of ADP-ribosyl groups onto target proteins, including mitochondrial GLUD1, inhibiting GLUD1 enzyme activity. Acts as a negative regulator of mitochondrial glutamine metabolism by mediating mono ADP-ribosylation of GLUD1: expressed in response to DNA damage and negatively regulates anaplerosis by inhibiting GLUD1, leading to block metabolism of glutamine into tricarboxylic acid cycle and promoting cell cycle arrest(PubMed:16959573). In response to mTORC1 signal, SIRT4 expression is repressed, promoting anaplerosis and cell proliferation(PubMed:23663782). Acts as a tumor suppressor(PubMed:23562301, PubMed:23663782). Also acts as a NAD-dependent protein deacetylase: mediates deacetylation of 'Lys-471' of MLYCD, inhibiting its activity, thereby acting as a regulator of lipid homeostasis(PubMed:23746352). Controls fatty acid oxidation by inhibiting PPARA transcriptional activation. Impairs SIRT1:PPARA interaction probably through the regulation of NAD(+) levels(PubMed:24043310, PubMed:20685656). Down-regulates insulin secretion(By similarity).
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。
