Abstract
By in vivo and in vitro methods of immunofluorescence, antibody to rat collagen and to rat kidney show the same regular, linear fluorescence following the outlines of the renal glomerular capillaries. Absorption of each antiserum with its homologous antigen completely removed the antibody for immunofluorescence, while absorption with the heterologous antigen had no effect. The nephrotoxicity persisted in the anti-kidney serum absorbed with collagen.
