Immunofluorescence staining of various tissues with antiheparin antibodies.
Cryosections of rat renal cortex, pancreas, and testis were stained with periplasmic fractions containing the antibodies. Bound antibodies were visualized by incubation with anti-VSV mouse monoclonal antibody P5D4, followed by Alexa 488–conjugated goat antimouse IgG. Staining intensity: ++, strong; +, moderate; +−, weak; −, absent (n=3). (a) Collecting ducts only.
