Localization of bovine pancreatic polypeptide (BPP)-like immunoreactivity in rat pancreatic monolayer culture.

Antiserum to bovine pancreatic polypeptide (BPP) has been used for immunofluorescent staining in the light microscope. With this technique it is possible to detect the presence of specific cells in monolayer culture from neonatal rat pancreas which contain BPP or a closely related peptide.
