Qualitative and quantitative evaluation of indirect immunofluorescent H-2 stain on tissue sections

Abstract

We have utilized H-2 specific antisera from congenic resistant donor recipient combinations to localize H-2 antigens in tissue sections using the indirect immunofluorescent technique. H-2 specific immunofluorescence is observed in spleen, kidney, and liver sections: however, especially with liver sections, there are cases in which the expected specific stain is weak or absent. In addition to microscopic evaluation by eye, we have employed a microscope attached photometer; recordings from this instrument differentiate positive from control stained spleen sections.
