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(chǔ)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(xiàng):
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Plays a role in the export of proteins that lack a signal peptide and are secreted by an alternative pathway. Binds two calcium ions per subunit. Binds one copper ion. Binding of one copper ion does not interfere with calcium binding. Required for the copper-dependent stress-induced export of IL1A and FGF1. The calcium-free protein binds to lipid vesicles containing phosphatidylserine, but not to vesicles containing phosphatidylcholine.

the IL1alpha-S100A13 tetrameric complex is the key complex formed during the non-classical pathway of IL1alpha release PMID: 21270123
S100A13 promotes the release of FGF-1 protein, but does not affect the transportation of FGF-1 protein in human umbilical vein endothelial cells. PMID: 20863990
S100A13 is expressed in melanocytic lesions when the angiogenic switch occurs and it may cooperate with VEGF-A in supporting the formation of new blood vessels, favoring the shift from radial to vertical tumor growth. PMID: 20208480
detected in both cells and fibers of the hippocampus at 12 weeks gestation, slightly stronger at 20 weeks, and then decreased with age. In the temporal cortex, strong in all cellular layers at 12 to 24 weeks, declined with age from 28 weeks onwards. PMID: 12645008
Stress-induced export of IL-1alpha involves the intracellular association with the Cu2+-binding protein, S100A13; the expression of a S100A13 mutant functions as a dominant-negative repressor of IL-1alpha release. PMID: 12746488
S100A13 protein translocation in response to extracellular S100 is mediated by receptor for advanced glycation endproducts in human endothelial cells PMID: 15033494

In human astrocytic gliomas, S100A13 was significantly up-regulated in high-grade vascularized gliomas. Moreover, S100A13 expression significantly correlated with microvessel density and tumour grading. PMID: 16773219
Human S100A13 was heterologously expressed in Escherichia coli, purified and crystallized by the hanging-drop vapour-diffusion method. PMID: 17077500
S100A13 is a homodimer with four EF-hand motifs in an asymmetric unit, displaying a folding pattern similar to other S100 members. S100A13 has the unique structural feature with all alpha-helices being amphiphilic. PMID: 17374362
Despite the high similarity of the backbone conformation in each protomer, the crystal structures of human S100A13 at pH 7.5 and at pH 6.0 exhibit recognizable differences in the relative orientation of the protomers within the dimer PMID: 18259052
