The PI(4,5)P2 Mass ELISA detects the amount PI(4,5)P2 extracted from cells by means of a competitive 96-well ELISA assay.
Assay Range: 250 to 0.016 pmol PI(4,5)P2Sample Type: Dried down lipid extracted from cellsSample Volume: 180 μL/sample, run in triplicate
The PI(4,5)P2 Mass ELISA assay is a competitive ELISA in which the signal is inversely proportional to the amount of PI(4,5)P2 produced.
Once PI(4,5)P2 has been extracted from cell samples, it is incubated with a PI(4,5)P2 detector protein, then added to the PI(4,5)P2-coated microplate for competitive binding. A peroxidase-linked secondary detection reagent and colorimetric substrate is used to detect the PI(4,5)P2 detector protein binding to the plate. The colorimetric signal is inversely proportional to the amount of PI(4,5)P2 extracted from cells.
Product BackgroundPhosphatidylinositol 4,5-bisphosphate, or PI(4,5)P2, is a ubiquitous lipid shown to play a central role in a variety of cell functions including the PKB/Akt pathway leading to cell growth, motility, inflammation, and apoptosis. PI(4,5)P2 is a substrate for class I phosphoinositide 3-kinase (PI3-K) and the product of PTEN phosphatase activity.
