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 GSK-3β Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of GSK-3β protein. A GSK-3β mouse mAb has been coated onto the microwells. After incubation with cell lysates, GSK-3β (phospho and nonphospho) protein is captured by the coated antibody. Following extensive washing, a GSK-3β rabbit mAb is added to detect the captured GSK-3β 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 the absorbance for this developed color is proportional to the quantity of total GSK-3β.Antibodies in kit are custom formulations specific to kit.

Background: Glycogen synthase kinase-3 (GSK-3) was initially identified as an enzyme that regulates glycogen synthesis in response to insulin (1). GSK-3 is a ubiquitously expressed serine/threonine protein kinase that phosphorylates and inactivates glycogen synthase. GSK-3 is a critical downstream element of the PI3K/Akt cell survival pathway whose activity can be inhibited by Akt-mediated phosphorylation at Ser21 of GSK-3α and Ser9 of GSK-3β (2,3). GSK-3 has been implicated in the regulation of cell fate in Dictyostelium and is a component of the Wnt signaling pathway required for Drosophila, Xenopus, and mammalian development (4). GSK-3 has been shown to regulate cyclin D1 proteolysis and subcellular localization (5).
