  • 产品描述：

    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.

■ 常见问题解答
Q:

What QC test will you perform?

A:
Quality Control:
1. Cloning Stage: Sequencing of the expression plasmid to ensure that the gene is completely correct. (Free of Charge. It is our routine detection.)
2. Protein Stage:
2.1. SDS-PAGE detection to determine purity and molecular weight (determine whether the observed value and the theoretical value are consistent). We comprehensively evaluate the purity through SDS-PAGE Coomassie brilliant blue staining detection and analysis using Bandscan software to ensure that the purity is more than 90%. (Free of Charge. It is our routine detection.)
2.2. Each batch will be tested for activity before shipped. (Free of Charge. It is our routine detection.)
2.3. WB detection (It is generally WB detection of tag-antibody, if there is a corresponding specific antibody, it will be arranged) to further determine the molecular weight of the protein (determine whether the observed value and the theoretical value are consistent) and its specificity. (Free of Charge. It will be performed upon customers' requests.)
2.4. AKTA-SEC test: For customers who need it, it can be used as a molecular sieve for further purification, while determining the purity and morphology of the protein (judging the presence of multimers). (Paid Service. It will be performed upon customers' requests.)
2.5. MS Identification: For customers who need it, we can arrange for mass spectrometry identification a separate sample. (Paid Service. It will be performed upon customers' requests.)
2.6. MS Identification: There is also a free monthly mass spectrometry identification (mixed samples will be detected). (Free of Charge. It is our routine detection.)
Q:

What is the general protectant? What kind of protectant do you usually add?

A:
Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.
Q:

When making TMPRSS2, do you use any protein denaturing purification steps?

A:
No, we don't use any protein denaturing purification steps. The protein is purified under mild conditions to avoid denaturation of the protein and to preserve the protein's natural state to the maximum.
Q:

Is TMPRSS2 soluble in water (buffer) or is it necessary to resuspend products in a solvent such as DMSO?

A:
It's soluble in Tris-buffer.
Q:

Was it difficult to manufacture TMPRSS2?

A:
The expression of TMPRSS2 is not difficult. We've expressed it successfully and have stable stock of it.
Q:

Do you know whether this product has been tested for activity?

A:
We're conducting activity testing for this protein. The activity data will be uploaded once the testing is finished.
Q:

I want to order 500 μg of CSB-YP023924HU. Would you let me know what form of the protein is provided (liquid or powder)?

A:
The default shipping form is lyophilized powder. If you want liquid form, we can also meet, please note when ordering.
Q:

Can you remove the endotoxin?

A:
Yes. We can provide endotoxin removal service free of charge and guarantee the endotoxin level to be less than 0.1ng/μg (1EU μg).
Q:

What is the general preservative? Which kind of preservative do you usually add?

A:
Commonly used preservative include Proclin 300, Sodium azide, etc. We do not add any preservative to our protein.

  • 功能：
    Plasma membrane-anchored serine protease that participates in proteolytic cascades of relevance for the normal physiologic function of the prostate. Androgen-induced TMPRSS2 activates several substrates that include pro-hepatocyte growth factor/HGF, the protease activated receptor-2/F2RL1 or matriptase/ST14 leading to extracellular matrix disruption and metastasis of prostate cancer cells. In addition, activates trigeminal neurons and contribute to both spontaneous pain and mechanical allodynia.; (Microbial infection) Facilitates human coronaviruses SARS-CoV and SARS-CoV-2 infections via two independent mechanisms, proteolytic cleavage of ACE2 receptor which promotes viral uptake, and cleavage of coronavirus spike glycoproteins which activates the glycoprotein for host cell entry. Upon SARS-CoV-2 infection, increases syncytia formation by accelerating the fusion process. Proteolytically cleaves and activates the spike glycoproteins of human coronavirus 229E (HCoV-229E) and human coronavirus EMC (HCoV-EMC) and the fusion glycoproteins F0 of Sendai virus (SeV), human metapneumovirus (HMPV), human parainfluenza 1, 2, 3, 4a and 4b viruses (HPIV). Essential for spread and pathogenesis of influenza A virus (strains H1N1, H3N2 and H7N9); involved in proteolytic cleavage and activation of hemagglutinin (HA) protein which is essential for viral infectivity.
