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(fù)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.

靶點詳情
功能:
Tumor suppressor. It blocks the growth, invasion, and metastatic properties of mammary tumors. As it does not undergo the S (stressed) to R (relaxed) conformational transition characteristic of active serpins, it exhibits no serine protease inhibitory activity.
基因功能參考文獻:
maspin is a powerful context-dependent tumor suppressor. PMID: 27923833
these data indicate that SerpinB5 expression and phosphorylation are developmentally regulated. In vitro analyses indicate that SerpinB5 phosphorylation is regulated by EGFR ligands, but EGF appears to be the only able to induce SerpinB5 nuclear localization. PMID: 27447178
perturbation of genes near maspin may in fact explain poor survival in certain patient cohorts with low maspin expression PMID: 24445777
evidence demonstrates that D(346) is a critical cis-element in maspin sequence that determines the molecular context and subcellular localization of maspin. PMID: 24278104
a novel mechanism by which maspin utilizes its cysteine thiols to inhibit oxidative stress and cell growth. PMID: 23471964
results suggest that maspin, a tumor suppressor, may play an important role in embryo implantation PMID: 22776050
The nuclear localization of maspin is required for its tumor and metastasis suppressor functions in vivo. PMID: 21502940
SERPINB5 and AKAP12 may have a role in increased metastasis in pancreatic ductal adenocarcinoma PMID: 20939879
PAR-1 negatively regulates the expression of the Maspin tumor-suppressor gene in the acquisition of the metastatic melanoma phenotype PMID: 21187389
Results describe a mechanism by which maspin exerts its effect on endothelial cell adhesion and migration through an integrin signal transduction pathway. PMID: 20713357
maspin exerts its tumor suppressive role, at least in part, by blocking the pericellular uPA system PMID: 12788977
Results show that deletion of maspin affects visceral endoderm function by reducing cell proliferation and adhesion, thereby controlling early embryonic development. PMID: 14985257
Maspin overexpression modulates tumor cell apoptosis through the regulation of Bcl2 family proteins PMID: 15907209
we believe that maspin is a tumour suppressor in malignant melanoma. PMID: 17371437
We propose that tumour-infiltrating RANKL-expressing cells lead to nuclear IKKalpha activation and inhibition of Maspin transcription, thereby promoting the metastatic phenotype PMID: 17377533
A partial loss of maspin caused an early developmental defect of the prostate and prostate hyperplastic lesions in mouse. PMID: 18593913
