Antiserum to PTEN,    

Prod.# P-1191-I  

From Rabbit.   Immunogen: Raised against a fusion protein containing the C-terminal human PTEN sequence. Specificity: Detects a ~60 kDa band of human, mouse and rat PTEN by Western Blot 

Research Applications: Immunoblotting:1:1000 Dilution, Immunoprecipitation: 1-2 ul/sample, Lipid Phosphatase Assay: Details available, IP-Phosphatase Assay: Details available.

PTEN plays an important role in the modulation of the 1-phosphatidylinositol 3-kinase pathway, by catalyzing the degradation of the PtdIns(3,4,5)P3 generated by PtdIns 3-kinase. This inhibits downstream functions mediated by PtdIns 3-kinase pathway.

Phosphoinositides play a central role in the regulation of numerous cell signaling processes. Their invovlement in cytoskeletal remodeling, vesicle trafficking, cell survival, mitogenesis, DNA repair, transcription regulation, exo-endocytosis, ion channel modulation, phagocytosis, and apoptosis have been reported.

Phosphoinositides are a form of lipids that have two fatty acid chains that insert into the membrane, and a water-soluble inositol ring head group that sticks out of the membrane into the cell. This inositol ring can be quickly modified via phosphorylation or dephosphorylation. This phosphorylation-dephosphorylation of phosphoinositides represents a mechanism for regulation signaling complexes and for the regulation of membrane proteins. The inositol ring can be phosphorylated at numerous positions and each of the resulting molecules can be recognized by specific proteins, enabling swift and accurate communication in the cell. is pleased to offer the most comprehensive offering of phosphoinositides, inositols and related products to the scientific community.
