The histone H5 variant in Xenopus laevis.

???displayArticle.abstract???
The presumptive histone H5 of Xenopus laevis has been characterized by SDS and acid-urea-Triton polyacrylamide gel electrophoresis and compared with chicken histone H5. Chicken H5 has a lower electrophoretic mobility compared to that of Xenopus H5 in both gel systems. It is shown, using a polyclonal antiserum against chicken H5, that the Xenopus histone H5 is immunologically related to chicken histone H5. Monoclonal antibodies have been prepared to the Xenopus histone types H5 and H1A, that do not cross-react, as determined by their reactivity in an enzyme linked immunosorbent assay and by their ability to react with either H1A or H5 in an immunochemical test on total erythrocyte histones that are transferred to nitrocellulose after fractionation by SDS- or acid-urea polyacrylamide gel electrophoresis. As all nuclei of erythrocytes from adult Xenopus laevis can be shown to contain histone H1A and H5, these monoclonal antibodies can be used to further delineate the role of H5 in tissue differentiation.
