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.
Constitutively active serine/threonine-protein kinase that exhibits growth-factor-independent kinase activity and that may participate in p53/TP53-dependent cell growth arrest signaling and play an inhibitory role during embryogenesis.

Suggest that RSK4 may serve as a mediator of endothelial progenitor cell senescence in diabetes mellitus. PMID: 22297070
The expression level of RSK-4 mRNA in breast cancer was significantly lower than those in normal breast tissues and breast benign lesions tissues. The down-regulation of RSK-4 expression in breast caner suggests that it is a breast cancer suppressor gene. PMID: 21875487
Data indicate that RSK4 appears to be epigenetically silenced in endometrial cancer as evidenced by hypermethylation. PMID: 21372219
importance of RSK4 for regulating senescence and indicate that downregulation of this kinase could be an important element in facilitating cell transformation. PMID: 21239520
The unusual regulation and growth factor-independent activity of ribosomal S6 kinase 4 (RSK4) indicate that it is functionally distinct from other RSKs and may explain why RSK4 can participate in non-growth factor signaling. PMID: 15632195
Downregulation of RPS6KA6 is associated with colon carcinoma. PMID: 16865262
RT-PCR data show high expression of putative tumor suppressor genes Rsk4 and RbAp46 in 47% and 79% of breast carcinoma cases, respectively, whereas Cldn2 was down-regulated in 52% of breast cancer cases compared with normal adjacent tissues. PMID: 17314274
RSK4 expression may limit the oncogenic, invasive, and metastatic potential of breast cancer cells. PMID: 18628456
Results support the concept that RSK4 may be an important tumor suppressor gene by modulating senescence induction and contributing to cell proliferation control in colon carcinogenesis and renal cell carcinomas. PMID: 19584160
