Trypsin (1:250) is a serine protease enzyme derived from porcine pancreas, widely used in biochemical research, cell culture, and protein digestion protocols. It cleaves peptide chains primarily at the carboxyl side of lysine and arginine residues, aiding in protein analysis, peptide mapping, and sample preparation. This product is standardized to a 1:250 activity ratio, ensuring consistent performance in applications like cell and tissue dissociation in cell culture, general protein digestion, and peptide sequencing. Store at -15 to -20 °C. Signal word: Danger. Molekula supplies Trypsin (1:250) from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
