Form Liquid or 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 If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is 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°C/-80°C. 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.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

(From Uniprot)
Significant glutathione conjugating activity is found only with the model substrate, 1-chloro-2,4-dinitrobenzene (CDNB).
Gene References into Functions
  1. Several biological properties of the GST-hNdCTR1 fusion protein were assessed. It was demonstrated that in cells, the protein was prone to oligomerization, formed inclusion bodies and displayed no toxicity. Treatment of E. coli cells with copper and silver ions reduced cell viability in a dose- and time-dependent manner PMID: 29099786
  2. we confirmed several existing chemoinformatic filters and more importantly extended them as well as added novel filters that specify compounds with anti-GST/GSH activity. Selected compounds were also tested using different antibody-based GST detection technologies and exhibited no interference clearly demonstrating specificity toward their GST/GSH interaction. PMID: 27044684
  3. Our findings indicate that the medical staff exposed to low IR levels were under risk of significant oxidative stress that was enhanced by their glutathione S-transferase (GST) polymorphisms. PMID: 28287017
  4. GSTK1 T/T genotype may be a novel risk factor for the prediction of overweight status in SCZ male patients. PMID: 27010189
  5. High glutathione-S-transferase is associated with type 2 diabetes mellitus. PMID: 27377684
  6. DsbA-L is localized in both the mitochondria and the endoplasmic reticulum (ER) in adipocytes; its ER localization plays a critical role in suppressing ER stress and promoting adiponectin biosynthesis and secretion. PMID: 25739441
  7. we have optimized the GST-Nck1-SH2 pull-down procedure to obtain tyrosine-phosphorylated proteins in tumor tissues PMID: 23426619
  8. drug resistance in three strains of tumor cells is associated with significant increase in hGSTP1 and hGSTA4 gene expression, whereas increased hGSTK1 gene expression was detected only in resistant erythroleukemia and mammary adenocarcinoma cells. PMID: 23330092
  9. This study does not give evidence of interaction between the GST polymorphisms and smoking may although this study provided sufficient statistical power to detect modest interaction. PMID: 20472488
  10. SNP-1308G/T (rs1917760) genotypes of DsbA-L gene might participate in insulin secretion and body fat distribution. It is possible that polymorphisms of DsbA-L gene associated with metabolic diseases[DsbA-L] PMID: 19225211
  11. structure and function characterization of a GST from human breast PMID: 14709161
  12. Gene and protein characterization; its subcellular localization in peroxisomes, suggesting a new function for this family of enzymes [glutathione S-transferase kappa (hGSTK1)] PMID: 14742434
  13. crystal structure of hGSTK1 has been determined by the multiple-isomorphous replacement method and refined to 1.93 A resolution PMID: 16081649
  14. Our results suggest that genetic polymorphisms of xenobiotic-metabolizing enzymes could play an important role in infertility. PMID: 18774560
  15. The objective of this study was to investigate the molecular mechanisms underlying Group B Streptococcus-human umbilical vein endothelial cells interaction, focusing specifically on the responsiveness of host protein tyrosine kinase (PTK). PMID: 19639233
  16. Observational study of gene-disease association. (HuGE Navigator) PMID: 19225211
  17. Observational study of gene-disease association. (HuGE Navigator) PMID: 17601350
  18. Presence of hGSTK1 in both peroxisomes and mitochondria. The C-terminus of hGSTK1 is essential for localization of the protein to peroxisomes, and the C-terminal sequence Ala-Arg-Leu represents a peroxisome targeting signal 1 (PTS1). PMID: 14742434
