THE NATURE OF TWO COMPONENTS OF PIG MUCOSAL HEPARIN, SEPARATED BY ELECTROPHORESIS IN AGAROSE GEL

Abstract

Two components of pig mucosal heparin were separated by agarose-gel electrophoresis and recovered from the gels. The slower moving component had the higher anticoagulant activity and intrinsic viscosity. The faster moving component had the higher sulfate : carboxyl ratio. Each component was degraded by self-hydrolysis to N-desulfated heparin, deaminated with nitrous acid, and hydrolyzed with formic acid. Two-dimensional electrophoresis and chromatography on thin layers of cellulose showed that each component had two uronic acids with the characteristics of glucuronic and iduronic acids.
