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.
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
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.
and FAQs
Protein FAQs
Storage Condition Store at -20°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 Data

Function Catalyzes the attachment of alanine to tRNA(Ala) in a two-step reaction
Gene References into Functions
  1. A large sequence divergence of the C-terminal domain (C-Ala) reshaped C-Ala in a way that changed the global architecture of alanyl-tRNA synthetase (AlaRS). This reshaping removed the role of C-Ala in prokaryotes for docking tRNA and instead repurposed it to form a dimer interface presenting a DNA-binding groove. PMID: 27911835
  2. Number of missense mutations in AARS expand the clinical spectrum and provide pheno-genotypic correlations in AARS-related neuropathies. PMID: 26032230
  3. A novel mutation in alanyl-tRNA synthetase causes a mild myeloneuropathy, a novel phenotype for patients with mutations in one of the tRNA synthetase genes. PMID: 25904691
  4. Loss-of-function alanyl-tRNA synthetase mutations cause an autosomal-recessive early-onset epileptic encephalopathy with persistent myelination defect. PMID: 25817015
  5. the pathological consequences of diminished tRNA synthetase editing activity, and thus translational infidelity, are dependent on the cell type and the extent of editing disruption PMID: 25422440
  6. in a family with distal hereditary motor neuropathy (dHMN), all 4 affected family members had a heterozygous missense mutation c.2677G>A (p.D893N) of (AARS), not found in the 4 unaffected members and control subjects; conclude AARS mutation caused dHMN in a Chinese family; AARS mutations result in not only a CMT phenotype but also a dHMN phenotype PMID: 22573628
  7. Methylation-mediated deamination of a CpG dinucleotide gives rise to the recurrent p.Arg329His alanyl-tRNA synthetase mutation in patients with Charcot-Marie-Tooth disease type 2N (CMT2N). PMID: 22009580
  8. We show here that mutations in AARS2 cause perinatal or infantile cardiomyopathy with near-total combined mitochondrial respiratory chain deficiency in the heart. PMID: 21549344
  9. cytoplasmic Alanyl-tRNA synthetase may have a role in dominant axonal Charcot-Marie-Tooth disease, as shown by its mutation in a major determinant for binding and aminoacylation PMID: 20045102
