- 背景介绍
- Involved in translation as a component of the 40S small ribosomal subunit(PubMed:8706699). Has endonuclease activity and plays a role in repair of damaged DNA(PubMed:7775413). Cleaves phosphodiester bonds of DNAs containing altered bases with broad specificity and cleaves supercoiled DNA more efficiently than relaxed DNA(PubMed:15707971). Displays high binding affinity for 7,8-dihydro-8-oxoguanine(8-oxoG), a common DNA lesion caused by reactive oxygen species(ROS)(PubMed:14706345). Has also been shown to bind with similar affinity to intact and damaged DNA(PubMed:18610840). Stimulates the N-glycosylase activity of the base excision protein OGG1(PubMed:15518571). Enhances the uracil excision activity of UNG1(PubMed:18973764). Also stimulates the cleavage of the phosphodiester backbone by APEX1(PubMed:18973764). When located in the mitochondrion, reduces cellular ROS levels and mitochondrial DNA damage(PubMed:23911537). Has also been shown to negatively regulate DNA repair in cells exposed to hydrogen peroxide(PubMed:17049931). Plays a role in regulating transcription as part of the NF-kappa-B p65-p50 complex where it binds to the RELA/p65 subunit, enhances binding of the complex to DNA and promotes transcription of target genes(PubMed:18045535). Represses its own translation by binding to its cognate mRNA(PubMed:20217897). Binds to and protects TP53/p53 from MDM2-mediated ubiquitination(PubMed:19656744). Involved in spindle formation and chromosome movement during mitosis by regulating microtubule polymerization(PubMed:23131551). Involved in induction of apoptosis through its role in activation of CASP8(PubMed:14988002). Induces neuronal apoptosis by interacting with the E2F1 transcription factor and acting synergistically with it to up-regulate pro-apoptotic proteins BCL2L11/BIM and HRK/Dp5(PubMed:20605787). Interacts with TRADD following exposure to UV radiation and induces apoptosis by caspase-dependent JNK activation(PubMed:22510408).
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。
