Trypsin is a kind of serine proteolytic enzyme, with molecular weight of 23300 dalton, and is a single peptide chain composed of 223 amino acid residues.
Chymotryupsin is white and light yellow crystal or amorphous powder,a kind of endopeptidase extracted from animal pancreas.
Trypsin-Chymotrypsin is the co-crystal of Chymotrypsin and Trypsin so it has the properties of both. It is stable when dry and easy to be inactivated in solutions.
Ribonuclease A has a molecular weight of 13,700 daltons . It operates in an optimum PH range of 7.0-7.5 .Mainly used for biochemical reagents.
Pancreatin extracted from pigs (cow) pancreas is a mixture of a variety of enzymes, white or light yellow amorphous powder .
