Antibodies to Histones and Histone-Histone Complexes: Immunochemical Evidence for Secondary Structure in Histone 1

Abstract
Highly specific antibodies were raised to histone 1 (H 1) and the histone complexes H32-H42 AND H2A-H2B, isolated by salt extraction. Antibody to H1 could detect irreversible conformational changes in acid- or urea-treated H1. The antibodies showed different reactivities with chromosomes as compared to antibodies in acid-extracted histones and should be useful in studies of native chromatin and chromosome structure.
