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.
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 Protects cells against membrane lipid peroxidation and cell death
Gene References into Functions
  1. Gpx4-catalyzed reduction of lipid hydroperoxides in lipid membranes has been described. PMID: 28709976
  2. MS/MS analysis of oxidized rat GPx4 complies with the predicted structure, an 8-membered ring, in which selenium is bound as selenenylamide to the protein backbone. PMID: 26163004
  3. mitochondria-targeted antioxidant SkQ1 (50 nmol/kg during 5 days) significantly increased the mRNA levels of Nrf2 transcription factor and Nrf2-induced genes encoding antioxidant enzymes SOD1, SOD2, CAT, and GPx4 in rat peripheral blood leukocytes. PMID: 26071777
  4. Our findings suggest that a decrease in mitochondrial GPx4 monomer and a functional loss of activity may be a contributing factor to the vulnerability of dopaminergic neurons in Parkinson's disease PMID: 23816523
  5. Rat Gpx4 is a moonlighting protein that functions both as a peroxidase, as well as a structural protein. PMID: 10464096
  6. Upon selenium fluctuation, the modulation of UGA recoding efficiency depends on the nature of the SECIS, with Gpx1 being more sensitive than Gpx4. PMID: 22614831
  7. activity in testis and epididymal spermatozoa of rats of different ages (phospholipid hydroperoxide glutathione peroxidase PHGPx, Gpx4). PMID: 11903656
  8. an important component of the mechanisms regulating inflammation PMID: 12397078
  9. gene is differentially spliced during the meiotic prophase and haploid cell phases of spermatogenesis PMID: 12533403
  10. PHGPx signals were detected in chromatoid bodies, clear nucleoplasm, mitochondria-associated material, mitochondrial aggregates, granulated bodies, and vesicles in residual bodies in addition to mitochondria, nuclei, and acrosomes during spermatogenesis. PMID: 12724282
  11. the nuclear PHGPx variant has a role in regulating cell division PMID: 12819198
  12. overexpression provides protection against damage from simulated ischemia/reoxygenation injury, particularly in the mitochondria, and the combination of mPHGPx and HSP60/10 imparts an added protective effect PMID: 14583338
  13. presence of traces of the larger snGPx form suggests that exhaustive proteolytic processing of the precursor produces the 25.9 kDa enzyme PMID: 15670826
  14. PHGPx activity in activated PMNs appears to be related to the appearance of the intrinsic function of PMNs in the inflammatory site. PMID: 15757501
  15. TGR and GPx4 can serve as a novel disulfide bond formation system and contain a catalytic selenocysteine consistent with the role of selenium in male reproduction PMID: 15901730
  16. PHGPx interacts with SMCP; the cysteine motif of PHGPx is a new substrate of the selenoperoxidase PMID: 16159880
  17. Astrocytic upregulation of GPx4 in response to injury is part of a protective cascade counteracting further cell damage in brain injury. PMID: 17603929
  18. We therefore propose that under persistent oxidative stress the formation of hepoxilin A3 and the HXA3-induced upregulation of PHGPx constitute a compensatory defense response to protect the vitality and functionality of the cell. PMID: 17997296
  19. liver and kidney Gpx4 activity in old female rats PMID: 19398061
  20. Data show that the intake of fish oil in the selenium-deficient animal led to a markedly altered formation of sperm nuclei glutathione peroxidase (snGPx), also designated as the nuclear form of PHGPx (n-PHGPx). PMID: 19723078
