背景
RCA1,also named as RNF53,plays a central role in DNA repair by facilitating cellular response to DNA repair. It is required for appropriate cell cycle arrests after ionizing irradiation in both the S-phase and the G2 phase of the cell cycle. The BRCA1-BARD1 heterodimer coordinates a diverse range of cellular pathways such as DNA damage repair,ubiquitination and transcriptional regulation to maintain genomic stability. BRCA1 acts by mediating ubiquitin E3 ligase activity that is required for its tumor suppressor function. It is involved in transcriptional regulation of P21 in response to DNA damage. BRCA1 is required for FANCD2 targeting to sites of DNA damage. It may function as a transcriptional regulator. BRCA1 inhibits lipid synthesis by binding to inactive phosphorylated ACACA and preventing its dephosphorylation. The antibody is specific to BRCA1. BRCA1 appears to produce multiple splice variants. BRCA1 is a nuclear protein with a molecular mass of 220 kDa. The present study describes the isolation and expression of two cDNAs of BRCA1,including a splice variant designated BRCA1D672-4095. BRCA1D672-4095 is generated by exclusion of exon 11 by in-frame splicing and produces a 97 kDa protein. In contrast to BRCA1,BRCA1D672-4095 localizes to the cytoplasm.

Q1:重组蛋白有活性吗?可以做活性检测吗?

活性说明的见说明书bio-activity部分;如果说明书显示没有生物活性或则显示生物活性检测中,则说明这个蛋白没有生物活性数据,需要客户自己检测。

Q2:重组蛋白是否测序验证过?

在售重组蛋白默认不做测序分析/验证。

Q3:蛋白的运输条件是什么?

我们的蛋白有液体和冻干粉2种形式,一般来说冻干粉可以用冰袋、蓝冰、干冰运输;液体可以用蓝冰或干冰运输。

Q4:蛋白是通过什么方式纯化的?

一般通过纯化标签进行亲和纯化,常规有镍柱/His Tag、protein AG/Fc tag、标签抗体凝胶等。

Q5:蛋白可以用于细胞培养/注射小鼠吗?

内毒素含量小于0.1 ng/μg (1 EU/μg)的蛋白都可以用于细胞培养/注射小鼠。

Q6:蛋白发货形式可以是冻干粉吗?可以发液体吗?

默认按照说明书标注的形式发货;如果有特殊需求,需要根据蛋白情况确定。原则上,冻干粉蛋白可以发液体形式,液体蛋白不能发冻干粉形式。

Q7:蛋白Buffer里是否含有denaturants(变性剂)?

我们在售重组蛋白一般不含变性剂,具体见说明书的formulation信息。常见变性剂有:尿素和盐酸胍。

Q8:无标签蛋白纯化方式?

蛋白的纯化方式一般通过标签进行亲和纯化,无标签的蛋白是在纯化后进行了标签切除。

Q9:AF蛋白可以提供吗?

在售的重组蛋白都属于Animal component free protein。在售重组蛋白里不含任何直接来源与动物和人的制品:比如血清,血浆,全血,BSA,OVA等。
