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.

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.

產品評價
靶點詳情
功能:
Involved in a TGF-beta pathway. May be a receptor for TGF-beta-like ligand daf-7. Controls the decision of whether or not larvae enter a developmentally arrested state, known as dauer, in response to environmental conditions. Regulates body size and male tail patterning. Involved in regulating entry into quiescence triggered by satiety. Involved in sensitivity to CO2 levels.
基因功能參考文獻:
alternative polyadenylation in intron 5 of daf-4 results in a 2.0 kb mRNA that encodes an open reading frame including only the N-terminal secretion signal and ligand-binding domains, and not the transmembrane or kinase domains PMID: 15254038
亞細胞定位:
Cell membrane; Single-pass type I membrane protein.
蛋白家族:
Protein kinase superfamily, TKL Ser/Thr protein kinase family, TGFB receptor subfamily
組織特異性:
Pharynx, intestine, hypodermis and body wall muscles in L1 through to adult stages. Also expressed in head neurons, ventral cord and tail neurons. Subset of head neurons show coexpression with daf-1 when dauer/nondauer decision is made.
