[Synthesis and properties of an affinity sorbent for extraction of atherogenic lipoproteins]

A digitonin-containing affinity sorbent was prepared using a hydrophilic polymer carrier. The correlation was found between the polymer structure and crosslink. King degree, on the one hand, and the sorbent capacity to bind cholesterol, protein and lipoproteins--on the other. The sorbent was demonstrated to extract predominantly atherogenic lipoproteins from blood plasma.
