Note: The complete sequence may include tag sequence, target protein sequence, linker sequence and extra sequence that is translated with the protein sequence for the purpose(s) of secretion, stability, solubility, etc.
If the exact amino acid sequence of this recombinant protein is critical to your application, please explicitly request the full and complete sequence of this protein before ordering.
蛋白標簽：

N-terminal 10xHis-tagged and C-terminal Myc-tagged
產品提供形式：

Liquid or Lyophilized powder Warning: in_array() expects parameter 2 to be array, null given in /www/web/cusabio_cn/public_html/caches/caches_template/default/content/show_product_protein.php on line 662
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
緩沖液：

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
復溶：

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
儲存條件：

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
保質期：

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
貨期：

3-7 business days
注意事項：

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

靶點詳情

功能：

Thought to be involved in DNA repair and/or mutagenesis. Its processivity is enhanced by the beta sliding clamp (dnaN) and clamp loader.
基因功能參考文獻：
1. polB gene expression is controlled by SOS and RpoS regulons. PMID: 28468910
2. Polymerases II, IV and V may bypass trans-4-hydroxy-2-nonenal modified bases by translesion synthesis and restore DNA synthesis beyond the arrested site, although with different efficiencies. PMID: 22001238
3. Data report that 15% of stress-induced mutations associated with DNA double-strand break repair in carbon-starved Escherichia coli requires high-fidelity Pol II, and that this component also requires RpoS. PMID: 20639336
4. transcription by single Pol II complexes allows survival of the original H3/H4 histones, while multiple, closely spaced complexes of transcribing Pol II can induce displacement of all core histones along the gene PMID: 20534568
5. Compared to the replicative B family polymerases, DNA Pol II has subtle amino acid changes remote from the active site that allow it to replicate normal DNA with high efficiency yet conduct translesion synthesis when needed. PMID: 20064374
6. The results fit a model in which Pol II acts as proofreader for HE-produced misinsertion errors. PMID: 16164549
7. These data suggest that DNA polymerase II is responsible for the in vivo mutagenic bypass of these lesions in wild-type E. coli. PMID: 16257273
8. elevated expression of Pol-II leads to an approximately 100-fold increase in spontaneous mutagenesis in a manner that is independent of SOS, umuDC, dinB, recA, uvrA and mutS functions PMID: 17586534
9. Data show that an important role is described for DNA Pol II in preventing the mutations and reveal that Pol II is a major editor of Pol III mediated replication errors. PMID: 18156258
