The invention provides a preparation method for anti-
lymphocyte immunoglobulin, which has the steps that human
peripheral blood T lymphocytes or human thymocyte is used for immunizing healthy pigs for collecting and separating
porcine plasma; after the manufacturing with 20 percent of
ethanol, components I plus II plus III deposit is separated by a low-temperature high-speed
centrifuge or a
filter press; after the manufacturing with 14 percent of
ethanol, supernatant fluid is separated and collected; after the manufacturing with 25 percent of
ethanol and
component II deposit is separated; subsequently, anti-
T cell porcine immunoglobulin is obtained after the steps of refinement, configuration and
virus inactivation of immunoglobulin, etc. Compared with the currently used
ammonium sulfate precipitation method, the technology of the invention has the advantages of
mass production, simple operation, easy command, short production period, little
reagent usage, low cost, no
pollution, and the like, which overcomes the disadvantages of the existing technology of hard realization of large-scale production, low yield, serious waste, environment
pollution, high production cost, complex production process, various service
chemical agents, long production period, high equipment occupation rate, etc.
