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
The following tags are available.
N-terminal His-tagged
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.
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
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.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Probable serine protease which may play a role in cellular senescence. Overexpression inhibits cell growth and induce G1 cell cycle arrest.
Gene References into Functions
  1. ECRG1 Arg290Gln polymorphism significantly affects the susceptibility but not the prognosis of esophageal squamous cell carcinoma patients in low-risk north Indian population. PMID: 23869757
  2. This suggests that substitution of the arginine in the conserved catalytic domain of the ECRG1 protein might reduce its catalytic capacity by impacting its 3-dimensional conformation, thereby causing the genetic susceptibility to ESCC. [review] PMID: 23548972
  3. Data show that the allele types of ECRG1 were Arg/Arg (54.2%), Arg/Gln (45.8%) and Gln/Gln (0.00%), and the allele types of FGFR4 amino acid 388 were Arg/Arg (8.3%), Arg/Gly (54.2%) and Gly/Gly (37.5%). PMID: 23481570
  4. A statistically significantly increased risk of ESCC was found to be associated with the ECRG1 Arg/Gln and Gln/Gln genotype. PMID: 21517269
  5. Data show that ECRG4 interacts directly with ECRG1 to upregulate p21 protein expression, induce cell cycle G1 phase block and inhibit cancer cells proliferation in ESCC. PMID: 21288367
  6. findings indicate that ECRG1 may be a candidate tumor suppressor gene for esophageal cancer involved in cell-cycle control PMID: 17971341
  7. DNA polymorphisms in the coding region of ECRG1 are associated with poor outcome after surgical resection in esophageal carcinoma. PMID: 19052822
  8. no significant association between single nucleotide polymorphisms Arg/Arg, Arg/Gln and Gln/Gln and survival in oral squamous cell carcinoma PMID: 19394797
  9. Observational study of gene-disease association. (HuGE Navigator) PMID: 19826048
  10. Observational study of gene-disease association. (HuGE Navigator) PMID: 19394797
  11. Observational study of gene-disease association. (HuGE Navigator) PMID: 19052822
