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
Methionine-sulfoxide reductase that specifically reduces methionine (R)-sulfoxide back to methionine. While in many cases, methionine oxidation is the result of random oxidation following oxidative stress, methionine oxidation is also a post-translational modification that takes place on specific residue. Upon oxidative stress, may play a role in the preservation of mitochondrial integrity by decreasing the intracellular reactive oxygen species build-up through its scavenging role, hence contributing to cell survival and protein maintenance.
Gene References into Functions
  1. this study we have identified, for the first time, compounds structurally related to the natural products fusaricidins that markedly activate recombinant bovine and human MsrA and human MsrB. PMID: 26718410
  2. Silencing the expression of the main Msr elements-MsrA, MsrB1, or MsrB2 exacerbates sensitivity toward oxidative stress. PMID: 23988788
  3. the mitochondrial methionine-R-sulfoxide reductase B2 (MSRB2) is a specific interaction partner of LG72. PMID: 25078755
  4. Data show that glutaredoxin acts as a reductant for methionine sulfoxide reductases A and B (MsrA and MsrB) with or without resolving cysteine. PMID: 22634633
  5. CBS1, a methionine sulfoxide reductase of type B, is most abundant in muscle tissues, especially in the heart and thereby shows an expression pattern different to the human methionine sulfoxide reductase A PMID: 12220640
  6. MSRB is down-regulated during cell aging. PMID: 14759519
  7. hMSRB2 expression was weak in brain, but strong in heart, skeletal muscle, and smooth muscle-containing organs (digestive system, bladder), lung and aorta, while hMSRB1 displayed a higher expression in liver and kidney PMID: 14980072
  8. showed the expression and function of both sulfoxide reductases together with thioredoxin reductase in the cytosol as well as in the nucleus of epidermal melanocytes which are especially sensitive to reactive oxygen PMID: 16480945
  9. Methionine sulfoxide reductases A and B are seriously affected by hydrogen peroxide accumulation in acute vitiligo. PMID: 17943184
  10. upon oxidative stress, the overexpression of methionine sulfoxide reductase B2 leads to the preservation of mitochondrial integrity by decreasing the intracellular reactive oxygen species build-up through its scavenging role PMID: 18424444
  11. almost absent catalase and methionine sulfoxide reductase A and B protein expression in human gray/white scalp hair shafts in association with a functional loss of methionine sulfoxide repair in the entire gray hair follicle PMID: 19237503
  12. MSR enzymes are differentially expressed in human skin. PMID: 19542914
