To probe the activities of sperm ADAM protein (fertilin,6), we devised a general synthetic strategy to generate fluorescently labeled fertilinbeta oligopeptide polymers. Immunofluorescence studies with these polymers demonstrated that fertilinbeta polymers bind specifically to a protein receptor on the mouse egg plasma membrane.

The ring-opening metathesis polymerization (ROMP) reaction is extraordinarily useful for the preparation of a large variety of polymers. We report that the length (n = 25-50) of high-substituent-density oligopeptide polymers synthesized by ROMP is dramatically improved upon addition of LiCl to reduce polymer and oligopeptide aggregation. This methodology should significantly expand the variety of polymers that may be prepared by ROMP and be of general use with norbornyl oligopeptides of any sequence.
