Polyclonal Rabbit Affinity Purified E B
PTEN (also know as MMAC1) was recently identified as a candidate tumor suppressor gene. Deletions or mutations within the PTEN gene have been observed in a variety of tumor cell lines and cancer cell types. Based on PTEN’s structural features, the protein was originally thought to be a protein tyrosine phosphatase. However, recent evidence indicates that PTEN is actually a lipid phosphatase rather that a protein tyrosine phosphatase. In fact, the target substrate for PTEN is phosphatidylinositol-3,4,5-triphosphate (Ptd-Ins(3,4,5)P3). Ptd-Ins(3,4,5)P3 is a critical second messenger involved in cell signaling and growth control. Ptd-Ins(3,4,5)P3 is produced by phosphorylation of Ptd-Ins(4,5)P2 by PI 3-kinase in response to stimulation by various ligands. By dephosphorylating Ptd-Ins(3,4,5)P3, PTEN functions to “turn off” the Ptd-Ins(3,4,5)P3 pathway and thereby suppress cellular proliferation.
Catalog #P9182-02
ApplicationsSuitable for use in ELISA, Western Blot. Other applications not tested.
Recommended DilutionELISA: 0.1–1.0ug/ml
Western Blot: 1–3ug/ml
Optimal dilutions to be determined by the researcher.
Storage and StabilityMay be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Freeze at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
