PIP Strips™ Membranes are designed to identify proteins with phosphoinositide recognition domains and use To analyze its lipid binding specificity. PIP Strips™ membranes facilitate the analysis of phosphoinositide-protein interactions via protein-lipid overlay methods. Proteins can be detected using standard Western blotting methods combined with a high-performance alkaline phosphatase and horseradish peroxidase (HRP)-mediated signal generation system.
