Summary
This report describes experimental conditions developed for the rapid and efficient preparation of guinea pig IgM in a purified form and in high yield. A combined immunization procedure had to be designed to obtain sufficiently high IgM concentrations in guinea pig serum. The isolation procedure includes precipitation at low pH, followed by sedimentation at 110,000 g and reverse flow gel chromatography on Sephadex G-200. Furthermore, we describe in detail the isolation of relatively large amounts of pure and specific anti-guinea pig μ-chain antibodies by immunoaffinity chromatography.
