Product Information

Product Description

CST's PathScan^® Phospho-PTEN (Ser380) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of phospho-PTEN (Ser380) protein. A PTEN Mouse mAb has been coated onto the microwells. After incubation with cell lysates, PTEN protein (phospho and non-phospho) is captured by the coated antibody. Following extensive washing, Phospho-PTEN (Ser380/Thr382/383) Antibody is added to detect the captured phospho-PTEN (Ser380). Anti-rabbit IgG, HRP-linked Antibody is then used to recognize the bound detection antibody. HRP substrate, TMB, is added to develop color. The magnitude of absorbance for this developed color is proportional to the quantity of phospho-PTEN (Ser380) protein.

*Antibodies in kit are custom formulations specific to kit.

Protocol

Specificity / Sensitivity

CST's PathScan^® Phospho-PTEN (Ser380) Sandwich ELISA Kit detects endogenous levels of phospho-PTEN (Ser380) protein. As shown in Figure 1 using the Phospho-PTEN (Ser380) Sandwich ELISA Kit #7285 a high level of phospho-PTEN (Ser380) is detected in HeLa cells. These levels are significantly reduced in HeLa cell lysates treated with λ phosphatase. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

Human, Mouse, Monkey

Background

PTEN (phosphatase and tensin homologue deleted on chromosome ten), also referred to as MMAC (mutated in multiple advanced cancers) phosphatase, is a tumor suppressor implicated in a wide variety of human cancers (1). PTEN encodes a 403 amino acid polypeptide originally described as a dual-specificity protein phosphatase (2). The main substrates of PTEN are inositol phospholipids generated by the activation of the phosphoinositide 3-kinase (PI3K) (3). PTEN is a major negative regulator of the PI3K/Akt signaling pathway (1,4,5). PTEN possesses a carboxy-terminal, noncatalytic regulatory domain with three phosphorylation sites (Ser380, Thr382, and Thr383) that regulate PTEN stability and may affect its biological activity (6,7). PTEN regulates p53 protein levels and activity (8) and is involved in G protein-coupled signaling during chemotaxis (9,10).
