Conjugate Avi-tag Biotinylated
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.

Tag Info
Tag type will be determined during the manufacturing process.
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.
Form
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.
Buffer before Lyophilization
Tris/PBS-based buffer, 6% Trehalose, pH 8.0
Reconstitution
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.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
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.
Lead Time
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.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
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.
Gene References into Functions
  1. 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
  2. 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
  3. Lack of ROPN1 had no effect on ciliary motility. PMID: 22021175
  4. 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
  5. 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
  6. 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
  7. One SNP (rs4499545) in the ROPN1-KALRN intergenic region showed significant allelic and genotypic association with ischemic stroke risk. PMID: 20107840
  8. 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
