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(chǎn)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(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:
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Exhibits adenosine 5'-monophosphoramidase activity, hydrolyzing purine nucleotide phosphoramidates with a single phosphate group such as adenosine 5'monophosphoramidate (AMP-NH2) to yield AMP and NH2. Hydrolyzes adenosine 5'-O-p-nitrophenylphosphoramidate (AMP-pNA). Hydrolyzes fluorogenic purine nucleoside tryptamine phosphoramidates in vitro. May be involved in steroid biosynthesis. May play a role in apoptosis.

Authors deduced that HINT2 triggers apoptosis in pancreatic cancer cells by regulating mitochondrial Ca(2+) influx through the mitochondrial calcium uniporter (MCU). Authors found that HINT2 can sensitize BxPC-3 and L3.6pl cells to gemcitabine-induced apoptosis and that gemcitabine up-regulates HINT2 expression. PMID: 28947137
HINT2 downregulation depended on hypoxia inducible factor (HIF)-2alpha-mediated transcriptional activation of zinc finger E-box-binding homeobox 1 (ZEB1). These results suggest that HINT2 downregulation promotes HIF-2alpha expression, which induces EMT and enhances CRC cell migration and invasion. PMID: 28088787
Low HINT2 expression is associated with low response to therapy in endometrial cancer. PMID: 23682076

Hint2 is required for an optimal steroidogenic response, possibly because of a particular signalling function exerted within the mitochondria. PMID: 18653718
