生物活性:
Recombinant Human TMPRSS2 His tag protein (CSB-YP023924HU) enzyme activity is measured by its ability to cleave fluorogenic peptide substrate(Boc-Gln-Ala-Arg-AMC), The Km is 21.93μM.
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.
緩沖液:
Tris-based buffer,50% glycerol
復溶:
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.
儲存條件:
Store at -20°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
保質期:
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.
貨期:
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
注意事項:
Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
產品描述:
The recombinant active human Transmembrane protease serine 2 (TMPRSS2) is produced by the expression of a target DNA sequence with 6xHis, N-terminal tag(s), in the yeast expression system. The target DNA sequence encodes the 106-492aa region of the human TMPRSS2. The purity of this partial-length protein is greater than 85% determined by SDS-PAGE. The gel showed a molecular weight band of about 45 kDa under reducing conditions. And its enzymatic activity was verified by its ability to cleave fluorogenic peptide substrate (Boc-Gln-Ala-Arg-AMC) (Km is 21.93μM).
The protease TMPRSS2 plays an important role in the infection mechanism of human coronaviruses, such as SARS-CoV and SARS-CoV-2. Cell entry of human coronaviruses depends on the binding of the viral spike (S) glycoprotein to cellular ACE2 receptor and S protein priming by host cell protease TMPRSS2. Moreover, TMPRSS2 protein is commonly used to study cancer. Previous studies have shown that the TMPRSS2 gene was up-regulated by androgenic hormones in prostate cancer cells and down-regulated in androgen-independent prostate cancer tissue.
