General description
A Rhodamine-B-labeled decapeptide derived from the (PIP2)-binding region in segment-2 of gelsolin. Acts as a cell-permeable, reversible, and non-toxic agent that transiently disrupts actin filaments, which are essential for cell morphology and cell motility (~1-10 µM). Specifically binds to polyphosphoinositide (PPI) with high affinity and activates platelets without significantly affecting intracellular Ca2+ influx. Undergoes a reduction in fluorescence intensity upon binding to phosphatidylinositol 4,5-bisphosphate (PIP2) and lysophosphatidic acid; the fluorescence is not affected in the presence of phosphatidylserine and phosphatidylcholine. Useful fluorescent probe for the cellular localization and stabilization of PPIs. Excitation max.: ~565 nm; emission max.: ~590 nm.
