Abstract

The present invention provides a production method for removing lipoprotein from horse serum. The production method for removing lipoprotein from horse serum comprises the following steps: rough filtering of horse serum through sterile gauze; preliminarily filtering a filtrate A through a filtering column; passing a filtrate B through a modified cellulose acetate filter membrane with a pore size of 0.05-1 [mu]m; conducting ultra-filtering by passing an obtained filtrate C through a hollow fiber ultrafiltration column with a molecular weight cut-off lower than 100 kD; placing the filtrate C obtained by the ultrafiltration in C18 resin for chromatography; placing a chromatographic effluent in a reaction tank and adding ethanol for precipitation; adding a Celite 503 adsorbent to a supernatantA; and adding a polysaccharide microsphere adsorbent to a supernatant B to prepare a lipoprotein-removed horse serum finished product. The method is simple and fast, stable in processes and also suitable for mass production, and can effectively remove lipoproteins and fibrin-containing proteins in the horse serum through layer-by-layer filtration and separation.

Description

technical field [0001] The invention relates to a method for separating lipoproteins, in particular to a production method for removing lipoproteins from horse serum. Background technique [0002] Human and animal blood is rich in proteins and enzymes that can heal and save lives. Some proteins are in red blood cells and some are in serum. Since the middle of the last century, the purification and separation of proteins has become an important direction of research. So far, the proteins that can be separated include: albumin, lipoprotein, fibrin, immunoglobulin G, etc. [0003] Horse serum is a large amount of natural medium used in the cultivation of cells and microorganisms. It is rich in nutrients necessary for the growth of cells and microorganisms. It is often used in the in vitro cultivation of animal cells and the cultivation of bacteria, mycoplasma, etc., and has extremely important functions. However, the horse serum currently available on the market is all deriv...
