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
Repressor that binds to DNA sequences containing a bipartite element consisting of a direct repeat of the sequence 5'-AAAGTTT-3' separated by 2-9 nucleotides. Represses basal transcription activity from target promoters. Inhibits colony formation in cultured breast cancer cells.
Gene References into Functions
  1. the present findings indicate that ST18 may play a direct role in Pemphigus vulgaris (PV) and consequently represents a potential target for the treatment of this disease. PMID: 27148741
  2. ST18 expression and activity are increased in cytotoxic conditions in pancreatic beta-cells. Overexpression of ST18 causes apoptosis. PMID: 24509857
  3. In our study, rs1015213 (located in the intergenic region between PCMTD1 and ST18) was associated significantly with primary angle closure. PMID: 23847314
  4. Presence of at least one A allele (AG or AA genotype) for rs1015213 was associated with a shallower anterior chamber depth (-0.07 mm, 95% CI -0.01 to -0.14 mm, p=0.028) after adjusting for age and sex (both pPMID: 23505305
  5. a significant association between ST18 and predisposition to Pemphigus vulgaris (PV). PMID: 22437316
  6. ectopic ST18 expression in MCF-7 breast cancer cells strongly inhibits colony formation in soft agar and the formation of tumors in a xenograft mouse model PMID: 15489893
  7. Fibroblasts that overexpress ST18 by transient transfection exhibit significantly increased apoptosis and increased expression of TNF-alpha, interleukin (IL) -1alpha, and IL-6. PMID: 18676404
