Inositol phosphates (IPs) are a group of mono to hexa-phosphorylated inositols. They play critical roles in diverse cellular functions including cell growth, apoptosis, cell migration, endocytosis and cell differentiation. Mono-, di-, and triphosphorylation of the inositol ring creates a wide range of stereochemically distinct signalling entities. For instance, inositol 1,4,5-trisphosphate (I(1,4,5)P3), is formed when the phosphoinositide phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2) is hydrolysed by a phospholipase C isozyme. An array of inositol trisphosphate (IP3) and tetrakisphosphate (IP4) molecules are synthesised by the action of various kinases and phosphatases in the cytosol. These species then transport between the cytosol and the nucleus where they are acted on by inositol polyphosphate multikinase (IPMK), inositol-pentakisphosphate 2-kinase (IPPK), inositol hexakisphosphate kinase 1 (IP6K1) and 2 (IP6K2), to produce IP5, IP6, IP7, and IP8 molecules. As a carbohydrate metabolism, inositol phosphate metabolism plays important roles in mammalians. Thus, its dysfunction is closely associated with various diseases like Joubert syndrome and Centronuclear myopathy.

Inositol phosphates contain multiple phosphorylated derivatives and individual PIPs can contain different fatty acid chains, resulting in structural complexity. Creative Proteomics has built a dedicated analytical platform to provide you with qualitative and quantitative analysis of inositol phosphates. Based on ion chromatography separation techniques, we are able to accurately determine the total amount of phosphorylated derivatives. Based on LC/MS technology, we are able to quantify phosphatidylinositol containing specific fatty acid chain structures.
