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:
Involved in the reprogramming of X-chromosome inactivation during the acquisition of pluripotency. Required for efficient elongation of TSIX, a non-coding RNA antisense to XIST. Binds DXPas34 enhancer within the TSIX promoter. Involved in ES cell self-renewal.
基因功能參考文獻:
Data show that zinc finger protein 42 (Rex1) and zinc finger and SCAN domain containing 4D/4C (Zscan4D/4C) correlate with the cell-cycle length under different mechanisms. PMID: 26997646
Results show that a novel pluripotency regulator, REX1, is essential for pluripotency and reprogramming. PMID: 23939908
Rex1 plays a role during preimplantation development and alters expression levels of Zscan4. PMID: 22897771
Results show that Rex1 regulates endogenous retroviral element expression in mouse embryonic stem cells and during pre-implantation development and suggest that Rex1 and its relatives have evolved as regulators of endogenous retroviral transcription. PMID: 22844087
RNF12 causes REX1 breakdown through dose-dependent catalysis, thereby representing an important pathway to initiate X-chromosome inactivation PMID: 22596162
the involvement of Rex-1 in control of Polycomb target genes during pluripotency or differentiation. PMID: 21530438
loss of Rex1 leads to impaired testicular function. PMID: 21641340
the functional connection of Rex1 to genomic imprinting represents another case where newly made genes have co-evolved with lineage-specific phenomena. PMID: 21233130
Rex-1 transcription factor regulates the differentiation of F9 stem cells along several distinct cell lineages found in the early embryo. PMID: 12354678
Embryonic stem cell marker Rex-1 and the pluripotent stem cell marker Oct-4 are spontaneously expressed by untreated mesenchymal stem cells. PMID: 16793732
Rex-1 marker was assessed using flow cytometry and gene expression profiling. PMID: 17518637
Rex1 should be regarded just as a marker of pluripotency without functional significance PMID: 18433507
The disruption of the Rex1 gene enhanced the expression of ectoderm, mesoderm, and endoderm markers as compared to wild-type embryonic stem cells PMID: 19618472
