Trypsin-1 (PRSS1), human, recombinant

Organism: Homo sapiens (Human). Source: Yeast. Expression Region: 24-247aa. Protein Length: Full Length of Mature Protein. Tag Info: C-terminal 6xHis-tagged. Target Protein Sequence: IVGGYNCEEN SVPYQVSLNS GYHFCGGSLI NEQWVVSAGH CYKSRIQVRL GEHNIEVLEG NEQFINAAKI IRHPQYDRKT LNNDIMLIKL SSRAVINARV STISLPTAPP ATGTKCLISG WGNTASSGAD YPDELQCLDA PVLSQAKCEA SYPGKITSNM FCVGFLEGGK DSCQGDSGGP VVCNGQLQGV VSWGDGCAQK NKPGVYTKVY NYVKWIKNTI AANS. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. 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. Storage: 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. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: 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.
