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.

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

Protein 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

Required for cytoplasmic partitioning and asymmetric cell division in early embryogenesis. Controls the asymmetric cell division of the Q.p neuroblast lineage. Involved in mediating cell polarization via regulation of anillin family scaffold proteins. Phosphorylates and restricts the asymmetry effectors mex-5 and mex-6 to the anterior cytoplasm of the zygote and maintains these phosphorylations until fertilization. May phosphorylate par-1. Required for strd-1 localization to the cell cortex of early embryos and may be required for strd-1 protein stabilization. May regulate the integrity of the early embryonic cortex in a strd-1-dependent manner. Phosphorylates and regulates aak-2 in response to oxidative stress and during dauer development. May also play a role in motility, behavioral response, regulation of lifespan and dauer formation through this pathway. Required to establish germline stem cell (GSC) quiescence during dauer development. Acts downstream of unc-40 in dendrite outgrowth. May play a role in cell shedding during embryogenesis, probably by phosphorylating pig-1.
