Swine anti Horse Ig light chains kappa and lambda (free and bound)

As tested in immunoelectrophoresis and double radial immunodiffusion against pooled normal horse serum and purified IgG fractions and light chain preparations, the antiserum reacts with determinants exposed on the surface (SD) and the Fab portion of all intact immunoglobulins, with Fab or F(ab’)2 subunits, and with free light chains of both types; also with determinants exposed only on free light chains but hidden in the intact immunoglobulin molecule (HD or hidden determinants) or Bence Jones proteins. This antiserum is not kappa or lambda chain specific. It does not react with any non-Ig protein in horse serum, as tested by immunoelectrophoresis and double radial immunodiffusion. As precipitating antiserum in a variety of immunodiffusion techniques including immunoelectrophoresis and double and single radial immunodiffusion Mancini, Ouchterlony). It has not been tested for use in nephelometry, ELISA or immunochemistry, but this does not exclude such use if proper controls are included.
