title: New nonradioactive technique for vasoactive intestinal peptide-receptor-ligand-binding studies.
abstract: We describe fluorescent-labeled peptide (FLP) studies on living cells. The new technique is nonradioactive and it allows monitoring of the binding and internalization of Vasoactive Intestinal Peptide (VIP) in VIP receptor-expressing cells. The technique is easy to perform and the observed reaction is peptide sequence specific.
