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
Acts as a negative regulator of the proliferation of normal cells by interacting strongly with CDK4 and CDK6. This inhibits their ability to interact with cyclins D and to phosphorylate the retinoblastoma protein.
Gene References into Functions
  1. Our findings indicated that p16 alteration is a common event in the carcinogenesis of this model and that the mutation pattern is analogous to that of human lesions. PMID: 25865695
  2. These findings indicate that p16(INK4a) plays a significant role in the inhibition of DNA synthesis. PMID: 24190239
  3. Ezh2 knockdown induced changes in DNA methylation of the p16INK4a gene and premature senescence in mesenchymal stem cells. PMID: 22873822
  4. Data show that an accumulation of p16(INK4a)-positive senescent astrocytes may link increased age and increased risk for sporadic Alzheimer's disease (AD). PMID: 22984612
  5. hIGF-1 gene therapy improved the expression of rIGF-1 and PCNA protein in myocardium, and also suppressed the expression of p16(INK4a) protein post-infarction. PMID: 18704299
  6. Maternal high fat exposure represses p16 (INK4a) gene expression in the mammary gland of offspring through changes of histone modifications and HDAC3 binding activity within the regulatory regions of the p16 (INK4a) gene. PMID: 22395468
  7. Subchronic grape juice concentrate administration was able to modulate cell cycle control by downregulation of p16 immunoexpression in high fat diet-induced liver steatosis in rats. PMID: 22320862
  8. In obesity prone rats, the increase of p16(INK4a) was associated with the higher acetylation levels of histone H4 at the p16(INK4a) promoter and coding region and lower methylation level of histone H3 lysine-27 in the p16(INK4a) coding region. PMID: 22194422
  9. Chromatin immunoprecipitation (ChIP) assay demonstrated that the altered p16 mRNA level and transcription rate in LP offspring resulted from histone code changes, including the reduced acetylation of histone H4 and the dimethylation of histone H3 PMID: 20934317
  10. These findings suggest that loss of function or decrease of RAR-beta2, RASSF1A, and CDKN2A, as well as the hypermethylation of 5' region of these genes, are related with nickel exposure. PMID: 21565688
  11. Chromosome aberrations of this protein in radiation-induced and spontaneous rat mammary carcinomas. PMID: 20681787
  12. iron-induced peritoneal mesothelioma associated with CDKN2A/2B homozygous deletion, supporting the hypothesis that oxidative stress by iron overload is a major cause of CDKN2A/2B homozygous deletion PMID: 20065947
  13. p16 (INK4A) locus is specifically vulnerable to oxidative damage, leading to its allelic loss within weeks, presumably due to a deficiency in the replication of both the alleles PMID: 11839561
  14. Mts1-expressing astrocytes play a role in degenerative events in the CNS white matter, interact with phagocytic microglia/macrophages, and regulate CNS cell migration and differentiation. PMID: 11870873
  15. The inhibitory effect of methylation on gene transcription was confirmed through RT-PCR expression studies in which p16 gene expression was 30-60-fold lower in methylated than unmethylated tumors PMID: 11872642
  16. methylation status of the 5' region was more closely correlated with p16 expression than that of the exon 1 alpha and analysis of the methylation status is useful in examining p16 silencing in various rat tumors. PMID: 12417039
  17. The p16 protein is mainly orientated in the cell nucleus and sporadically orientated in the cytoplasm. PMID: 15144691
  18. Inactivation by hypermethylation of the promoter region of p16INK4A gene was related to carcinogenesis of oral cancer. PMID: 15201967
  19. Ink4a and Arf have roles in mammalian aging PMID: 15520862
  20. Both of these closely spaced ATG start codons can be utilized as a translational start codon to produce a nucleolar-localized ARF protein which can induce a p53-dependent inhibition of cell division PMID: 16760664
  21. In rats, the non-genotoxic carcinogen phenobarbital produced reversible changes in the methylation region of the p16 gene. PMID: 17706854
  22. INK4a/ARF gene expression is reduced in stem-like sphere cells from rat sarcomas PMID: 17761140

  25. Hypertension induces cellular senescence via p16(INK4a), possibly through p38, thereby contributing to hypertensive target organ damage. PMID: 18504326
  26. Ink4a/Cdk4/Rb1 pathway deregulation, more than Arf/Mdm2/Tp53 pathway, has a major role in the development of these tumors through p16(Ink4a) deregulation. PMID: 18656278
  27. PPARalpha trans-repression involved the recruitment of the retinoblastoma (RB) family proteins p107 and p130 to the TERT promoter resulting in impaired E2F-1 binding, an effect that was dependent on p16. PMID: 18818403
  28. Results suggest that p16CDKN2A mutations in exon 2 are not involved in the multistep tongue carcinogenesis nduced by 4NQO. PMID: 19255859
