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:
Transcription factor involved in the regulation of the insulin signaling pathway. Binds to insulin-response elements (IREs) and can activate transcription of IGFBP1. Down-regulates expression of HIF1A and suppresses hypoxia-induced transcriptional activation of HIF1A-modulated genes. Also involved in negative regulation of the cell cycle. Involved in increased proteasome activity in embryonic stem cells (ESCs) by activating expression of PSMD11 in ESCs, leading to enhanced assembly of the 26S proteasome, followed by higher proteasome activity. Represses smooth muscle cell differentiation by inhibiting the transcriptional coactivator activity of myocardin.
