Induced Color Change of Conjugated Polymeric Vesicles by Interfacial Catalysis of Phospholipase A2.

Sheldon Yoshio Okada1, Raz Jelinek2, Deborah Charych3.   

Abstract

A blue to red color change is induced on addition of phospholipase A2 to modified PDA vesicles 1 (PDA=polydiacetylene). This bathochromic transition results from chemical modification of the vesicles by hydrolysis of the enzyme substrate embedded in the PDA matrix. Addition of a known phospholipase inhibitor or removal of Ca2+ ions suppresses the color change, which suggests the potential for applications in high-throughput screening assays. © 1999 WILEY-VCH Verlag GmbH, Weinheim, Fed.
