Abstract

A large body of data suggests that the linker histones family (H1) affects gene expression. Investigation of the linker histones role is then of a major interest in cell cycle studies with implications in gene therapy. Indeed, it has been shown that in most tissues a switch of histone subtypes occurs when the cells cease to divide. To investigate linker histone role in gene or transgene expression, an antibody against subtypes of H1 would be useful for immunoprecipitation experiments and further assays measuring H1subtypes-DNA interactions in living cells. In order to produce an antibody against the H1e subtype of linker histones, two synthetic peptides derived from two regions of the H1e mouse histone protein were examined for their potential, [as keyhole limpet hemocyanin (KLH) conjugates] to elicit polyclonal anti-H1e antibodies in New Zealand white rabbits. Selection of the peptide sequences was based on amino acid differences within the different classes of histones and between mice and rabbit histones as well. The evaluation of their potential immunogenic properties was based on examination of peptide hydropathy using predicting algorithms. Immunoglobulins (IgG) obtained from immunized and nonimmunized rabbits were tested using enzyme-linked immunosorbent assay (ELISA) procedures, Western immunoblot, and immunofluorescence experiments. Results showed that the selected synthetic peptides gave rise to a high-liter polyclonal antibody able to recognize the H1e histone under various conditions. This polyclonal antibody did not cross-react with other histones. To our knowledge, this is the first antibody produced against the mouse H1e linker histone.
