title: Anti-rat CD45RA monoclonal antibodies cross-react with glucagon.
abstract: Anti-rat CD45RA monoclonal antibody (MAb) has been used as a marker for rat B-lymphocytes (B-cells). When we applied the MAb to identify B-lymphocytes among immune cells infiltrating pancreatic islets of the BB rat, which is an animal model for human type 1 diabetes mellitus, a subpopulation of islet cells was immunostained as well. Our immunohistochemical investigations demonstrated that the stained islet cells are pancreatic alpha-cells and the MAb cross-reacts with glucagon.
