Bacteriophage T4 gene 32 protein shares antigen determinants with reconstituted HeLa hnRNP proteins in western blots.
A polyclonal antiserum against purified bacteriophage T4 gene 32 protein was raised in rabbits. In Western blots it detected a number of SDS-PAGE separated nuclear and ribosomal proteins of HeLa cells. Using a renaturing blotting system, however, larger hnRNP proteins ranging between 66.000 and 82.000 Da preferentially reacted with this antiserum. In addition hnRNP group A core proteins were detected to a minor extent. Nucleic acid binding proteins like histones or ribosomal proteins were not stained by this antibody after renaturation.
