Product Description

PolyPIPosomes are polymerized liposome-like nanoparticles (~200 nm) which show markedly increased stability (up to 6 months) vs. conventional liposomes. A biotin tag is incorporated for easy detection of PIP_n-binding proteins with streptavidin reagents or coated surfaces.
PolyPIPosomes have demonstrated utility in a number of assay formats:

Protein pull-down
Surface Plasmon Resonance
Liposome overlay assay

PI(3,4)P₂ PolyPIPosomes are provided as a 1mM total lipid solution containing 5% PI(3,4)P₂. Each order of 250 μL or 1 mL of PolyPIPosomes includes 100 μL of Control PolyPIPosomes.
