assay and reagents for drug discovery in lipid signaling pathways
Catalog No.: P-6100
Description: PIP Arrays are 4 x 5 cm hydrophobic membranes that have been spotted with a concentration gradient of all eight phosphoinositides. They are used to determine the relative degree of binding of your protein of interest towards one or more of these lipids in a simple protein lipid overlay assay. Bound protein is then detected by an antibody against the protein or affinity tag.
Each PIP Array has 100, 50, 25, 12.5, 6.25, 3.13, and 1.56 pmol of the following phosphoinositides:
Phosphatidylinositol (3) phosphate (PtdIns(3)P)
Phosphatidylinositol (4) phosphate (PtdIns(4)P)
Phosphatidylinositol (5) phosphate (PtdIns(5)P)
Phosphatidylinositol (3,4) bisphosphate (PtdIns(3,4)P2 )
Phosphatidylinositol (3,5) bisphosphate (PtdIns(3,5)P2)
Phosphatidylinositol (4,5) bisphosphate (PtdIns(4,5)P2)
Phosphatidylinositol (3,4,5) trisphosphate (PtdIns(3,4,5)P3)
Each 5-pack of PIP Arrays includes a free vial of the PI(4,5)P2 specific binding protein (G-4501) for use as a positivie control. For a list other phosphoinositide binding proteins, click here.
