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.

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.

Protein FAQs
Storage Condition Store at -20°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 Data

Function Ras proteins bind GDP/GTP and possess intrinsic GTPase activity (By similarity). Plays an important role in the regulation of cell proliferation
Gene References into Functions
  1. Kras protein mutation is responsible for the development of mucinous adenocarcinoma of the lung in patient born with congenital pulmonary malformation. PMID: 27645976
  2. Taken together, these results reveal the key role of histone H3Kme in TGF-beta1 mediated p21 gene expression in RMC, partly through HMT SET7/9 occupancy, suggesting H3Kme and SET7/9 may be potential renoprotective agents in managing chronic renal diseases. PMID: 27247942
  3. Study provided evidence of antiapoptotic effect of miR-30b in early phase of rat myocardial I/R injury model via the Ras/Akt pathway and showed KRAS as a target involved in miR-30b mediated anti-apoptotic effect. PMID: 25925903
  4. VEGF/VEGFR/K-ras signaling pathway might promote the occurrence and development of hepatocellular carcinoma cells through regulating expression of miRNA21, which has potential clinical value for the development of therapies for hepatocellular carcinoma PMID: 25730004
  5. Findings demonstrated that oncogenic K-Ras activates the signaling cascade p38/PDPK1/PKCdelta/p47(phox)/NOX1 for ROS generation and consequent malignant cellular transformation. PMID: 24632950
  6. Piper betle may act as a potential chemopreventive agent in the early stage of colon carcinogenesis by suppressing the expressions of beta-catenin and KRAS. PMID: 24617038
  7. beta-cell apoptosis can be triggered by p21 during stress and is thus a potential target to inhibit for protection of functional beta-cell mass. PMID: 23592481
  8. Oncogenic K-Ras modulates expression and localization of catenin and HDAC proteins in Rat2 cells. PMID: 23747726
  9. Data indicate that Ras-Raf-ERK-Sp1 signaling pathway is responsibe for FGF-2-induced nestin expression. PMID: 23611784
  10. mitochondrial functional loss may be mediated by oncogenic K-Ras-induced mitophagy during early tumorigenesis even in the absence of hypoxia PMID: 21738012
  11. It appears that p21Ras induces asthmatic ASMCs to a proliferative/secretory phenotype, but its inhibitor FTP III, can significantly reverse this phenotype. PMID: 21362304
  12. Vascular smooth muscle cell proliferation is influenced by let-7d microRNA and its interaction with KRAS. PMID: 21266788
  13. limited clinical usefulness of gene mutation as a selection marker for epidermal growth factor receptor tyrosine-kinase inhibitors sensitivity in non-small cell lung cancer PMID: 20022659
  14. The proto-oncogenic k-Ras is directly involved in the promotion of muscle differentiation via PI3K and its downstream signaling pathways. PMID: 20603646
  15. Reactive oxygen species, Ki-Ras, and mitochondrial superoxide dismutase cooperate in nerve growth factor-induced differentiation of PC12 cells PMID: 20495008
  16. Genome-wide gene expression analysis identifies K-ras as a regulator of alcohol intake. The data implicate K-ras-regulated pathways in the regulation of excessive alcohol drinking after a history of dependence PMID: 20388501
  17. N-nitroso-N-methylurea disrupted and dietary methylselenocysteine significantly increased the expression of p21 in mammary glands of Fischer 344 rats PMID: 20424134
  18. study shows social isolation decreases content of Bcl-2-associated K-Ras in hippocampal mitochondria but amount of H-Ras is increased in the microsomal fraction; redistribution of Ras isoforms was accompanied by acceleration in mitochondrial hexokinase PMID: 19616040
  19. SCOP bound through its LRR domain with a subset of K-ras in the raft fraction, interfering with the binding of added guanine nucleotide to K-Ras. PMID: 12594205
  20. AGEs signal to Ki-Ras and ERK through reactive oxygen species-dependent activation of PI3K. PMID: 12871951
