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:
Histone methyltransferase that specifically trimethylates 'Lys-9' of histone H3 in ovary. H3 'Lys-9' trimethylation represents a specific tag for epigenetic transcriptional repression by recruiting Su(var)205/HP1 to methylated histones. Plays a central role during oogenesis.
基因功能參考文獻:
Study identified a H3K9 methyltransferase, SETDB1/eggless, a Drosophila homologue of the mammalian SETDB1, which confers the robustness for the precise determination of bristle number. PMID: 26914287
Mosaic analysis also reveals that the early egg chamber budding defects in egg- ovaries are due to an intrinsic requirement for egg in follicle stem cells and their descendents PMID: 24485852
The results showed that on chromosome 4, Su(var)3-9, SETDB1 and HP1a target the same genes. PMID: 23476027
dSet1 is responsible for the bulk of H3K4 di- and trimethylation throughout Drosophila development. PMID: 22048023
this study has revealed the essential roles of Eggless (Egg), a H3K9 methyltransferase in controlling stem cell maintenance and differentiation through distinct mechanisms. PMID: 22216012
egg is required in the ovary for trimethylation of histone H3 at its K9 residue. PMID: 17164421
results indicate that dSETDB1 and SU(VAR)3-9 act together with distinct roles during oogenesis, with dsetdb1 being of particular importance due to its germline stem cell-specific function and more severe mutant phenotype PMID: 18493619
The genetic interactions between dSETDB1 and Su(var)3-9 mutations emphasize the importance of maintaining the activities of these histone methyltransferases in balance for normal genome function. PMID: 19189944
Together with Egg, Wde localizes to euchromatin, is enriched on chromosome 4, and binds to the Painting of fourth (POF) protein. PMID: 19750210
