  • Function

    Has activity against the synthetic substrates Boc-Phe-Ser-Arg-Mec, Boc-Leu-Thr-Arg-Mec, Boc-Gln-Ala-Arg-Mec and Boc-Val-Pro-Arg-Mec. The single-chain form is more active than the two-chain form against all of these substrates.
  • Involvement in disease

    Defects in PRSS1 are a cause of hereditary pancreatitis (HPC) [MIM:167800]; also known as chronic pancreatitis (CP). HPC is an autosomal dominant disease characterized by the presence of calculi in pancreatic ducts. It causes severe abdominal pain attacks.
  • Sequence similarities

    Belongs to the peptidase S1 family.
    Contains 1 peptidase S1 domain.
  • Post-translational

    Occurs in a single-chain form and a two-chain form, produced by proteolytic cleavage after Arg-122.
  • Cellular localization

    Secreted > extracellular space.
  • Information by UniProt

Customer reviews and Q&As


Thank you for your enquiry.

Trypsin is a protease enzyme, and the ab78527Trypsinprotein has been tested as active. If the fluoresent protein the customer wishes to use is known to contain one of thesubstrate sequencesof the trypsin enzyme, then it may work:

Trypsin substrates:
Boc-Phe-Ser-Arg-Mec, Boc-Leu-Thr-Arg-Mec, Boc-Gln-Ala-Arg-Mec and Boc-Val-Pro-Arg-Mec.

However, I am sorry to confirm that this protein has has never been tested in this type of application. All tested applications that we can guaranteeare specified on our datasheets, and these are updated as soon as any new information is brought to our attention.

If the customer would like to try the product, we like to encourage all of our customers to submit an Abreview via the online product datasheet, and the customer may like to consider this. We always appreciate customer feedback, whether positive or negative, and we make all product information available to researchers. Plus, each Abreview earns Abpoints that can be used for discounts on future purchases or rewards such as gift certificates.
