Abstract

The invention provides a preparation method and applications of pig spleen transferfactor. According to the preparation method, frozen-breaking, freeze thawing breaking, and centrifugal process are combined for transferfactor production, yield is guaranteed, and at the same time production temperature is reduced, and the activity of the transferfactor can be guaranteed preferably. And in addition, the prepared transferfactor contains no protein, is a small molecular peptide, possesses no pyrogen, is a widely used immunomodulator, is capable of increasing vaccine titer, and can be used for improving animal immunity and improving production performance; the activity is not influenced by pancreatic enzymes; and no toxic reaction is caused. When the pig spleen transferfactor is combined with vaccine, animal immunity can be improved, vaccine titer is increased at the same time, body immune response period is shortened, and antibody lasting time is prolonged.

Description

technical field

[0001] The invention relates to the technical field of veterinary biological products, in particular to a preparation method and application of pig spleen transfer factor. Background technique

[0002] Transfer factor (TF for short) is a substance released by lymphocytes that can transfer sensitization information. It does not contain protein and is a small molecular polypeptide. It has the functions of transmitting immune information, regulating immune function, and enhancing immune function of the body. TF has no pyrogen and is not destroyed by trypsin. The activity of TF is unstable to heat and stable under freezing conditions. It can specifically transfer the donor's cellular immune information to the recipient, thereby enhancing the immune function of the recipient. At present, it has become a widely used immune-enhancing preparation in foreign countries.
