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.
Interacts with host ephrinB2/EFNB2 or ephrin B3/EFNB3 to provide virion attachment to target cell. This attachment induces virion internalization predominantly through clathrin-mediated endocytosis.

G and the fusion protein F are both crucial glycoproteins located on the surface of the virus envelope. [review] PMID: 29963835
the binding of the viral attachment protein G to its host receptor ephrinB2 was studied and showed monomeric and dimeric receptors activate distinct conformational changes in G. PMID: 28974687
Data suggest that fusion of Nipah viruses with host cells is facilitated by two of viral membrane proteins, the G protein and the F protein; G head domain binds to human ephrins B2 and B3 altering conformational density of entire G head domain. PMID: 24615845
Authors identified a G stalk C-terminal region (amino acids 159 to 163) that is important for multiple G functions, including G tetramerization, conformational integrity, G-F interactions, receptor-induced conformational changes in G, and F triggering. PMID: 25428863
Cysteine cluster in the G protein is involved in stabilizing a unique microdomain critical for triggering fusion. PMID: 22496210
Results indicated that the G-H loop of ephrin-B2 was indeed critical for the interaction between ephrin-B2 and Nipah virus-G. PMID: 21632558
the G protein appeared to be constitutively internalized with the bulk flow during membrane turnover PMID: 15731282
sNiV-G binds to ephrinB3 with a 30-fold higher affinity than that of sHeV-G. PMID: 17652392
report the crystal structures of the NiV-G both in its receptor-unbound state and in complex with ephrin-B3, providing, to our knowledge, the first view of a paramyxovirus attachment complex in which a cellular protein is used as the virus receptor PMID: 18632560
