CST's PathScan® Cleaved Caspase-3 (Asp175) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of cleaved caspase-3 protein. A Cleaved Caspase-3 (Asp175) Rabbit mAb has been coated onto the microwells. After incubation with cell lysates, the cleaved caspase-3 protein is captured by the coated antibody. Following extensive washing, a Biotinylated Caspase-3 Rabbit Antibody is added to detect the captured cleaved caspase-3 protein. HRP-linked streptavidin is then used to recognize the bound detection antibody. HRP substrate, TMB, is added to develop color. The magnitude of optical density for this developed color is proportional to the quantity of cleaved caspase-3 protein.Antibodies in kit are custom formulations specific to kit.

Background: Caspase-3 (CPP-32, Apoptain, Yama, SCA-1) is a critical executioner of apoptosis, as it is either partially or totally responsible for the proteolytic cleavage of many key proteins, such as the nuclear enzyme poly (ADP-ribose) polymerase (PARP) (1). Activation of caspase-3 requires proteolytic processing of its inactive zymogen into activated p17 and p12 fragments. Cleavage of caspase-3 requires the aspartic acid residue at the P1 position (2).

The PathScan® Total PTEN Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenously expressed PTEN. A PTEN rabbit antibody has been coated onto the microwells. After incubation with cell lysates, PTEN is captured by the coated antibody. Following extensive washing, a PTEN mouse detection antibody is added to detect the captured PTEN. Anti-mouse IgG, HRP-linked antibody is then used to recognize the bound detection antibody. HRP substrate (TMB) is added to develop color. The magnitude of the absorbance for this developed color is proportional to the quantity of PTEN.Antibodies in kit are custom formulations specific to kit.

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).

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) Antibody is added to detect the captured phospho-PTEN (Ser380) protein. 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.

The PathScan® Phospho-Src (Tyr416) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of phospho-Src (Tyr416). A phospho-Src rabbit antibody has been coated onto the microwells. After incubation with cell lysates, phospho-Src (Tyr416) is captured by the coated antibody. Following extensive washing, a Src mouse detection antibody is added to detect the captured phospho-Src (Tyr416). Anti-mouse, HRP-linked antibody is then used to recognize the bound detection antibody. The HRP substrate, TMB, is added to develop color. The magnitude of the absorbance for this developed color is proportional to the quantity of phospho-Src (Tyr416).Antibodies in kit are custom formulations specific to kit.

Background: The Src family of protein tyrosine kinases, which includes Src, Lyn, Fyn, Yes, Lck, Blk, and Hck, are important in the regulation of growth and differentiation of eukaryotic cells (1). Src activity is regulated by tyrosine phosphorylation at two sites, but with opposing effects. While phosphorylation at Tyr416 in the activation loop of the kinase domain upregulates enzyme activity, phosphorylation at Tyr527 in the carboxy-terminal tail by Csk renders the enzyme less active (2).
