Bromelain from pineapple stem min. 0.2 DMC-U/mg, powder, SERVA

Opis towaru

Bromelain is a non-specific cysteine endopeptidase (thiol proteinase) suitable for degradation of proteins like casein, collagen, globulin, hemoglobin. It is used in blood group serology. The protease digests preferably at lysine, alanine, tyrosine and glycine. It has a temperature optimum at 50 - 65 °C and a pH optimum of 5 - 6.

Activity in other units: 1200 GDU units/g, 2400 FIP units/g
Unit definition: 1 DMC-U catalyzes the cleavage of 1 µmole peptide bond from dimethyl casein per minute at 25 °C, pH 7.0 expressed in terms of newly formed terminal amino groups (determined with TNBS).
Unit definition GDU: 1 GDU unit yields the equivalent of 1 mg amino nitrogen from gelatin in 20 min at 45 °C, pH 4.5.
