Isoelectric point of cell-free K99 antigen exhibiting hemagglutinating properties
Infect Immun.
1978 Mar.
Abstract
The isoelectric point of the K99 antigen in partially purified preparations isolated from Escherichia coli B41 was 4.2. Electrofocused K99 antigen hemagglutinated guinea pig and sheep erythrocytes and gave a single precipitin line on diffusion against antisera to E. coli B41 and absorbed factor K99 antisera.
