    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.

  • 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.

靶點詳情

  • 功能：
    CAalpha-CAbeta-CAgamma: The acidic subunit of crotoxin (CA) is a heterotrimer of three disulfide-linked chains generated by post-translational maturation of a PLA2-like precursor. CA has no PLA2 activity and is not neurotoxic by itself, but plays several important functions in the crotoxin complex by increasing the lethal potency of the uncomplexed CB subunit. It acts by physically occluding the hydrophobic interfacial binding surface (IBS) of CB. This effect decreases the adsorption of CB to phospholipid membranes, targeting the crotoxin complex to reach the specific presynaptic receptor (R48) at the neuromuscular junction. It also prevents the formation of the reactive CB dimer. Moreover, the CA subunit inhibits the catalytic activity by partially masking the catalytic site of CB and inhibits its anticoagulant activity.; Heterodimer CA-CB: Crotoxin is a potent presynaptic neurotoxin that possesses phospholipase A2 (PLA2) activity and exerts a lethal action by blocking neuromuscular transmission. It consists of a non-covalent association of a basic and weakly toxic PLA2 subunit (CBa2, CBb, CBc, or CBd), with a small acidic, non-enzymatic and non-toxic subunit (CA1, CA2, CA3 or CA4). The complex acts by binding to a specific 48-kDa protein (R48/CAPT) receptor located on presynaptic membranes, forming a transient ternary complex CA-CB-R48, followed by dissociation of the CA-CB complex and release of the CA subunit. At equilibrium, only the CB subunits remain associated with the specific crotoxin receptor. In addition to neurotoxicity, crotoxin has been found to exert myotoxicity, nephrotoxicity, and cardiovascular toxicity. Moreover, anti-inflammatory, immunomodulatory, anti-tumor and analgesic effects of crotoxin have also been reported.; found in the venom as a monomer and stabilized by one disulfide bond (Cys-131 and Cys-138). This peptide induces potent antinociceptive effects in acute and chronic pain models. This effect is mediated by the release of peripheral dynorphin A, an endogenous agonist of kappa-opioid receptors, and this release is dependent on cannabinoid receptor CB2 activation.
