Trypsin specifically cleaves C-terminal peptide bonds of lysine and arginine, which can degrade intercellular binding proteins. The amino acid sequence of the recombinant trypsin produced by Hzymes Biotech is the same as that of porcine pancreas-derived trypsin, and is produced by recombinant Escherichia coli expression. It can replace traditional extraction of trypsin for cell digestion in vaccines, stem cells, immune cell therapy, drug screening, antibodies and other fields. Aprotinin, soybean trypsin inhibitor, etc. can distinctly inhibit enzyme activity. Recombinant trypsin has the same properties as naturally extracted trypsin. This product is manufactured in a GMP grade workshop. No animal-origin raw materials are used in the fermentation, purification, and final ingredients. At the same time, the production and quality control processes are validated, resulting in a high level of consistency between batches.

Product Instruction
- Solution preparation: Melt the recombinant trypsin at room temperature, take an appropriate amount of trypsin according to the protein content of COA, and add HBSS equilibration solution (or other buffer suitable for cell digestion. If necessary, add EDTA to a final concentration of 0-1mM, it is best not to exceed 2mM). The recommended trypsin concentration is about 0.1-0.3mg/mL (concentration adjusted according to different cells), and gently mixed; this step can be operated at room temperature.
- Use a 0.22μm filter to filter the trypsin solution and transfer it to a sterile container; this step can be operated at room temperature.
- The filtered trypsin solution should be used directly as required on the day (for example, adding 1mL to T25 bottles, digesting cells at 37°C), and the liquid can be stored at 2-8°C for 1-2 weeks.
- Long-term storage: If the prepared recombinant cell digestion solution needs to be stored for a long time, it can be stored stably at -20°C for 12 months.
