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.

USF-1 but not USF-2 was strongly enriched at Dbeta2 in chromatin from either Rag2-/- double-negative thymocytes or Rag2-/- thymocytes that express a rearranged Tcrb transgene. PMID: 22287717
Blood oxytocin concentrations on d 9 postpartum were also lower in Usf2-/- mice than Usf2+/+ mice PMID: 12907752
transcription factors upstream stimulatory factor (USF) and c-Myc may exert opposing effects on PIGR promoter activity PMID: 14644095
USF2 inhibited cellular transformation by preventing transcriptional repression by c-Myc. PMID: 15541720
Wild-type and USF2 knockout mice exhibited a 2.5-fold stimulation of renal TGF-beta1 expression upon fasting. PMID: 15983197
USF2 might be one of the regulators for the expression of the Runx2 gene in D1 cells. PMID: 16786196
Hyperglycemia stimulated USF2 expression in glomeruli from diabetic mice, associated with TSP1, TGF-beta, and fibronectin in glomeruli, leading to diabetic nephropathy. Overexpression augmented injury. PMID: 17881461
