Abstract

The invention belongs to the field of veterinary biological products, and particularly relates to a method for rapidly producing transfer factors. The method includes the main steps of tissue homogenization, enzymatic hydrolysis, acid-base digestion, ultrasonic extraction, centrifugation, ultrafiltration, and the like. Compared with the traditional freeze-thaw process, the method has the advantages that the reagents adopted by the method are simple, the cost is low, cells are more fully broken, the production cycle is short, a lot of manpower and material resources are saved, the cost is significantly reduced, and the method is suitable for large-scale production of economic animal products.

Description

technical field [0001] The invention belongs to the field of veterinary biological products, and in particular relates to a method for rapidly producing transfer factor. Background technique [0002] Transfer factor is a dialyzable small-molecule polypeptide and nucleotide complex released by immune-competent T lymphocytes in human or animal white blood cells. Studies have found that it has a good preventive effect on various animal diseases. The preparation of transfer factor mostly adopts the method of repeated freezing and thawing to disrupt cells, but this method has disadvantages such as long operation time (6-8 days), easy to be infected with bacteria, and unstable active ingredients. [0003] Chinese patent ZL201510782710.9, a process for preparing transfer factor capsules, introduces a process for preparing transfer factor capsules. After filtering, filtering, sterilizing and freeze-drying, the transfer factor freeze-dried powder is obtained, and starch, microcrysta...
