The Activity of Complement in the Presence of N-(2-hydroxypropyl)methacrylamide Copolymers

Abstract
This study indicates that N-(2-hydroxypropyl)methacrylamide homopolymers and copolymers containing oligopeptide sequences terminated in carboxylic acid groups, amine groups, aromatic units, or puromycin have no prominent effect on the porcine complement system in vitro. Inhibition of both pathways of the complement system occurred at concentrations highly exceeding the dose suitable for therapeutic purposes.
