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.

產(chǎn)品提供形式：

Lyophilized powder Warning: in_array() expects parameter 2 to be array, null given in /www/web/cusabio_cn/public_html/caches/caches_template/default/content/show_product_protein.php on line 662
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(fù)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(zhì)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(xiàng)：

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

靶點(diǎn)詳情

功能：

Gating-modifier toxin that potently inhibits inactivation of the mammalian Nav1.1/SCN1A sodium channel (EC(50)=38 nM). Also moderately inhibits inactivation of Nav1.2/SCN2A (EC(50)=236 nM) and Nav1.3/SCN3A (EC(50)=220 nM) when the channels are expressed in oocytes without the beta-1 auxiliary subunit. Does not inhibit inactivation of Nav1.2/SCN2A when the channel is coexpressed with the beta-1 auxiliary subunit. When tested on Nav1.1/SCN1A channel, it enhances peak current amplitude and potently delays channel inactivation in a dose-dependent manner, leading to a large sustained current. It has no effect on the voltage-dependence of steady-state activation, and induces a depolarizing shift in the voltage dependence of inactivation. In addition, it does not modify the recovery from fast inactivation in Nav1.1/SCN1A. The binding affinity and subtype selectivity of the toxin towards Nav1.1/SCN1A channel is determined by residues within both the S1-S2 and S3-S4 loops of the domain IV voltage sensor of the channel. This toxin also weakly inhibits several subtypes of voltage-gated potassium channels. It moderately blocks Kv2.1/KCNB1 (23% inhibition at 100 nM), Kv2.2/KCNB2 (19.7% at 100 nM and 51% at 300 nM), Kv4.1/KCND1 (IC(50)=280 nM), Kv4.2/KCND2 (39% at 300 nM) and Kv4.3/KCND3 (43% at 300 nM). In vivo, intracerebroventricular injection into mice elicits convulsions, spasms, tremors and rapid death. When injected into mouse hindpaw, the toxin elicits an immediate and robust response to pain. However, intraplantar injection of toxin does not cause neurogenic inflammation or alter sensitivity to heat, indicative of a modality-specific effect on mechanosensitive neurons. In Dravet syndrome mice model, intracerebroventricular infusion of this peptide rescues mice from seizures and premature death.
