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.
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.
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.
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.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Metalloreductase that has the ability to reduce both Fe(3+) to Fe(2+) and Cu(2+) to Cu(1+). Uses NAD(+) as acceptor.
Gene References into Functions
  1. High STEAP1 expression is associated with prostate cancer. PMID: 29464393
  2. Data suggest a solid basis for further research into understanding how six-transmembrane epithelial antigen of prostate member 1 (STEAP1) activities may affect cancer progression. PMID: 27792302
  3. These findings highlight the ability of immuno-PET with (89)Zr-2109A to detect acute changes in STEAP1 expression PMID: 25453051
  4. Data indicate that six transmembrane epithelial antigen of the prostate 1 (STEAP1) is consistently overexpressed in malignant prostate tissue, namely adenocarcinoma and prostatic intraepithelial neoplasia (PIN) lesions. PMID: 24239460
  5. The findings provide evidence that STEAP1 is a biomarker of worse prognosis in prostate carcinomas patients. PMID: 24025158
  6. STEAP1 is down-regulated by dihydrotestosterone and estradiols in LNCaP cells and in rat prostate. PMID: 23060075
  7. A total of 62.3% of the Ewing's Sarcoma samples displayed detectable STEAP1 expression with predominant localization of the protein at the plasma membrane. PMID: 22317770
  8. STEAP1 is associated with the invasive behavior and oxidative stress phenotype of Ewing tumors, an unanticipated oncogenic function of STEAP1. PMID: 22080479
  9. STEAP1 overexpression predicts improved outcome of Ewing's sarcoma patients, possibly due to enhanced sensitivity towards ROS-generating chemotherapeutics. PMID: 22317770
  10. EWS-FLI1 mediated overexpression of STEAP1 increases the invasiveness and oxidative stress levels of Ewing tumor cells. PMID: 22080479
  11. Data suggest that zoledronic acid may affect cancer cells also by targeting the gene expression of STEAP. PMID: 19915386
  12. Peptide STEAP-292.2L (MLAVFLPIV) may have potential as an antitumor peptide vaccine. PMID: 15958640
  13. STEAP mRNA is used here as a marker to evaluate biological samples from individuals suspected of having cancers, and may provide prognostic information useful in defining appropriate therapeutic options. PMID: 18793824
  14. STEAP1 is over-expressed in breast cancer and down-regulated by 17beta-estradiol. PMID: 18958632
  15. STEAPs may represent novel markers of mesenchymal stem cells in man as well as mice. PMID: 19196137
