Abstract
Precipitates soluble in aqueous solution and suitable for stimulation and/or transfer of cell-mediated immunity in mammals and other animals is disclosed together with a solvent extraction process for obtaining this desirable product from crude bovine transfer factor. Lymphocytes from lymph nodes and blood of donor cattle are employed in formulating a Bovine Transfer factor by incubation release procedure. The fractionation of Bovine Transfer factor yields three precipitate fractions by the use of organic solvents. A relatively high incidence of transfer with the precipitates yields excellent immunity to certain diseases in animals.
