Recombinant Human His6-UBE2R1/CDC34 Protein, CF Summary
Product Datasheets
Carrier Free
CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins.Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration.The carrier free version does not contain BSA.
In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard.In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: UBE2R1/CDC34
Ubiquitin-conjugating Enzyme H3 (UbcH3), also known as Cell Division Cycle 34 (Cdc34), is a member of the Ubiquitin-conjugating (E2) enzyme family (1). UbcH3 has a predicted molecular weight of 26 kDa. The human protein shares 98% amino acid (aa) sequence identity with the mouse and rat orthologs. In addition to an E2 catalytic core domain, UbcH3 has two Ubiquitin binding sites, UBS1, from aa 205-215, and UBS2, from aa 216-225, and a C-terminal acidic tail domain (2,3). UbcH3 is required for efficient cell cycle progression in human cells (4). UbcH3 interacts with the SCF(Fbw7) and SCF(Skp2) Ubiquitin ligases (E3s) to target the key cell cycle proteins Myc and p27/Kip1, respectively, for ubiquitination and degradation (4,5). Furthermore, CK2 has been shown to phosphorylate human UbcH3 on Ser203, Ser222, and Ser231 in cycling cells (6). The proliferation of cancer cell lines is inhibited following treatment with a human UbcH3 inhibitor, suggesting that UbcH3 also plays a significant role in cancer (7). This protein has an N-terminal His6-tag.

1.如果在引物的5’引物引入了T7启动子,3‘引物也引入了polyT,PCR扩增出全长片段,回收纯化之后可以用来直接做体外转录么?为什么看到文献里都是先把这个PCR片段连接到载体里面,扩增之后提取出来线性化之后,再进行体外转录。是不是转录对模板的量有要求?
2.如果使用一些带有T7启动子序列的载体比如pBluescriptSK,在启动子序列和酶切位点之间还有多余的一段序列,这段序列也会被启动子转录,这一小段多余的序列是否会对接下来的转染以及病毒拯救带来影响?
3.有人在做反向遗传么,哪些载体可以用来进行体外转录?插入片段为7.5K。
