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.
Important for male fertility. With ROPN1L, involved in fibrous sheath integrity and sperm motility, plays a role in PKA-dependent signaling processes required for spermatozoa capacitation.
基因功能參考文獻:
There is downregulation of both ROPN1 and CABYR in asthenozoospermic samples and importantly, a positive correlation between the expression of the two genes, suggesting that ROPN1 and CABYR co-expression is a prerequisite for normal flagellar function and sperm motility. PMID: 29247344
Ropporin gene expression is related to the sperm motility. Its abnormal expression in the sperm of asthenozoospermic men with varicocele is associated with impaired sperm motility that is improved after varicocelectomy. PMID: 25704993
Lack of ROPN1 had no effect on ciliary motility. PMID: 22021175
We suggest that ropporin is a promising target for MM immunotherapy, as we were able to generate human leukocyte antigen class I-restricted cytotoxic lymphocytes able to kill autologous MM cells. PMID: 21654522
CABYR variants form a complex not only with the scaffolding protein AKAP3 but also with another RII-like domain-containing protein in the sperm fibrous sheath. PMID: 21240291
ropporin was predominantly expressed in round spermatids in human testis, and located in the principal piece and end piece of spermatozoa flagella. Expression level of ropporin was significantly lower in asthenozoospermic men than in normozoospermic men. PMID: 20705794
One SNP (rs4499545) in the ROPN1-KALRN intergenic region showed significant allelic and genotypic association with ischemic stroke risk. PMID: 20107840
Ropporin gene expression in tumor cells is associated with the presence of high titer IgG antibodies against Ropporin, suggesting the in vivo translation of the mRNA into protein and the immunogenicity of the protein to the autologous hosts. PMID: 17551920
