Conjugate Avi-tag Biotinylated
E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

Tag Info
Tag type will be determined during the manufacturing process.
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Form
Lyophilized powder
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.
Buffer before Lyophilization
Tris/PBS-based buffer, 6% Trehalose, pH 8.0
Reconstitution
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.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
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.
Lead Time
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling.
Gene References into Functions
  1. The histone modification domain of Paf1 complex subunit Rtf1 directly stimulates H2B ubiquitylation through an interaction with Rad6. PMID: 27840029
  2. These results indicate that eukaryotic cells respond to RNAPII arrest by deubiquitylating H2B to coordinate DNA repair and RNAPII degradation. PMID: 25136098
  3. Data indicate that histone H2B repression (HBR) domain is important for FACT (consisting of Spt16/Pob3) histone chaperone activity. PMID: 24248595
  4. this study provides evidence that only small levels of H2BK123ub are necessary for full levels of H3K4 and H3K79 trimethylation in vivo and points to a possible role for Chd1 in positively regulating gene expression through promoting nucleosome reassembly coupled with H2B monoubiquitination. PMID: 22549955
  5. Histone H2B ubiquitylation and H3 lysine 4 methylation prevent ectopic silencing of euchromatic loci important for the cellular response to heat. PMID: 21680712
  6. Results describe a novel role for the H2B C-terminal helix in the trans-histone cross talk as a binding surface for Set1-COMPASS. PMID: 20439497
  7. propose a structural model by which H2B R102 and K111 regulate the binding of the Sir complex to the nucleosome PMID: 20479120
  8. Disruption of Lge1 abolished ubiquitylation of histone H2B on lysine 123 and H3 methylation on lysines 4 and 79 PMID: 19923226
  9. Lge1p has roles in gene regulation independent of its participation in the Rad6p-dependent ubiquitination of H2B PMID: 15528187
  10. H2B-Lys-123 ubiquitination has roles in regulation of H3-Lys-4 methylation and recruitment of RNA polymerase II PMID: 16675445
  11. Histone H2B deacetylation at lysine 11 is required for yeast apoptosis induced by phosphorylation of H2B at serine 10 PMID: 17052455
  12. Sgf73 provides a molecular scaffold to integrate the regulation of H2B ubiquitin levels, tethering of a gene to the NPC and export of mRNA PMID: 18488019
  13. some of the biological effects of ubiquitylation of H2B are exerted via ubiquitin chains, rather than a single ubiquitin group PMID: 18562693
  14. the role of Sus1 in nuclear pore complex targeting of an mRNA export complex and histone H2B deubiquitination PMID: 19269973
