| titleOfInvention | Preparation method for chymotrypsin |
| abstract | The invention provides a preparation method for chymotrypsin. The preparation method comprises the following process procedures: (1), grinding raw material and extracting protein; (2) salting out in a grading manner to obtain a crude product of chymotrypsin; (3), feeding the crude product and crystallizing in a multiple manner; (4), activating; (5), salting out; (6), dialyzing; and (7), freeze-drying. According to the invention, a set of large-scale manufacturing technology is established and has the advantages of simplicity, low cost and the like; the titer of a fine product of prepared chymotrypsin is more than 1,200 unit/milligram; and the prepared chymotrypsin meets the requirements of Chinese pharmacopeia (2010) and has very great market competitiveness. |
