PolyPIPosomes are polymerized liposomes that show markedly increased stability (up to 6 months) vs. conventional liposomes. A biotin tag is incorporated for easy detection of PIPn-binding proteins with streptavidin reagents. - Uniform size (~200 nm) - Ready-to-use suspensions, no liposome preparation PolyPIPosomes have demonstrated utility in a number of assay formats: Protein pull-down Surface Plasmon Resonance Liposome overlay assay PI(3,4,5)P3 PolyPIPosomes are provided as a 1mM total lipid solution containing 5% PI(3,4,5)P3. Each order of 250 µL or 1 mL of PolyPIPosomes includes 100 µL of Control PolyPIPosomes.
