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.

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.
產品提供形式：

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.
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：

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.
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：

Botulinum toxin causes flaccid paralysis by inhibiting neurotransmitter (acetylcholine) release from the presynaptic membranes of nerve terminals of the eukaryotic host skeletal and autonomic nervous system, with frequent heart or respiratory failure. Is unique among characterized BoNTs in having 2 substrates, syntaxin (STX) and SNAP25. Precursor of botulinum neurotoxin C which unlike most BoNTs seems not to have a proteinaceous coreceptor, and instead recognizes 2 different complex polysialylated gangliosides found on neural tissue probably found in synaptic vesicles. Upon synaptic vesicle recycling the toxin is taken up via the endocytic pathway. When the pH of the toxin-containing endosome drops a structural rearrangement occurs so that the N-terminus of the heavy chain (HC) forms pores that allows the light chain (LC) to translocate into the cytosol. Once in the cytosol the disulfide bond linking the 2 subunits is reduced and LC cleaves its target protein on synaptic vesicles, preventing their fusion with the cytoplasmic membrane and thus neurotransmitter release. In vitro the whole toxin only has protease activity after reduction. Electrical stimulation increases uptake of toxin, presumably by transiently exposing a receptor usually found in eukaryotic target synaptic vesicles. Forms ion-conducting channels at around pH 6.1. Requires complex eukaryotic host polysialogangliosides for full neurotoxicity. Synaptic vesicle glycoproteins (SV2) do not seem to act as its receptor.; Has proteolytic activity. After translocation into the eukaryotic host cytosol, inhibits neurotransmitter release by acting as a zinc endopeptidase that cleaves syntaxin-1A/STX1A and syntaxin-1B/STX1B. Cleaves the '253-Arg-|-Ala-254' bond of STX1 and the '252-Arg-|-Ala-253' bond of STX2; also acts on syntaxin 3 (STX3) but not 4 (STX4). Cleaves the '198-Arg-|-Ala-199' bond of SNAP25. Recognizes the '93-Asn--Met-202' region of SNAP25.; Responsible for host epithelial cell transcytosis, host nerve cell targeting and translocation of light chain (LC) into eukaryotic host cytosol. Composed of 3 subdomains; the translocation domain (TD), and N-terminus and C-terminus of the receptor-binding domain (RBD). The RBD is responsible for the adherence of the toxin to the eukaryotic target cell surface. It simultaneously recognizes 2 polysialated gangliosides coreceptors in close proximity on host synaptic vesicles. The N-terminus of the TD wraps an extended belt around the perimeter of the LC, protecting Zn(2+) in the active site; it may also prevent premature LC dissociation from the translocation channel and protect toxin prior to translocation. The TD inserts into synaptic vesicle membrane to allow translocation into the host cytosol. The C-terminal half of the HC (residues 864-1291) binds neurons in a dose-dependent manner. The C-terminal half of the HC (residues 863-1291) binds eukaryotic host gangliosides in the order GD1b > GT1b > GD1a > GM1a. Has 2 ganglioside binding sites; Sia-1 prefers a sia7 sialic acid and sugars within the ganglioside (GD1b > GT1b), whereas GBP2 recognizes a sia5 sialic acid (GT1b and GD1a). Both sites are required for HC to enter neurons, acting via different gangliosides. This suggests that 2 gangliosides serve as toxin receptors. Synaptic activity (depolarization with K(+)) increases uptake by neurons. Treatment of synaptosomes with proteinase K does not reduce HC binding, suggesting there is no protein receptor or it is protected from extracellular proteases. Decreases uptake and toxicity of whole BoNT/A, but also interferes with uptake of BoNT/E and BoNT/F. HC also binds phosphoinositides, which might play a role in membrane-binding.
