PathScan® Phospho-Akt1 (Ser473) Sandwich ELISA Kit #7160
Figure 2: Treated and untreated NIH/3T3 lysates are assayed on #7160 Phospho-Akt1 (Ser 473) and #7170, Total Akt1 Sandwich ELISA kits. Total Akt1 levels can be detected in both treated and untreated lysates. Phospho-Akt1 (Ser 473) is detected only in the PDGF treated cells. The corresponding Western blots probing with #4058 and #9272 are shown in the bottom figure.Learn more about how we got this image

CST's PathScan® Phospho-Akt1 (Ser473) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of phospho-Akt1 (Ser473) protein. Phospho-Akt (Ser473) Rabbit mAb has been coated on the microwells. After incubation with cell lysates, phospho-Akt (Ser473) protein is captured by the coated antibody. Following extensive washing, Akt1 Mouse Antibody is added to detect the captured phospho-Akt1 (Ser473) protein. 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 absorbance for this developed color is proportional to the quanitity of phospho-Akt1 (Ser473) protein.
Antibodies in kit are custom formulations specific to kit.
CST's PathScan® Phospho-Akt1 (Ser473) Sandwich ELISA Kit #7160 detects endogenous levels of phosphorylated Akt1 at Ser473. Inhibition of phosphorylation of Akt1 (Ser473) by LY294002 in Jurkat cells is shown in Figure 1. Treatment of NIH/3T3 cells with PDGF to induce phosphorylation of Akt1 (Ser473) is also shown in Figure 2. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.
Akt, also referred to as PKB or Rac, plays a critical role in controlling survival and apoptosis (1-3). This protein kinase is activated by insulin and various growth and survival factors to function in a wortmannin-sensitive pathway involving PI3 kinase (2,3). Akt is activated by phospholipid binding and activation loop phosphorylation at Thr308 by PDK1 (4) and by phosphorylation within the carboxy terminus at Ser473. The previously elusive PDK2 responsible for phosphorylation of Akt at Ser473 has been identified as mammalian target of rapamycin (mTOR) in a rapamycin-insensitive complex with rictor and Sin1 (5,6). Akt promotes cell survival by inhibiting apoptosis through phosphorylation and inactivation of several targets, including Bad (7), forkhead transcription factors (8), c-Raf (9), and caspase-9. PTEN phosphatase is a major negative regulator of the PI3 kinase/Akt signaling pathway (10). LY294002 is a specific PI3 kinase inhibitor (11). Another essential Akt function is the regulation of glycogen synthesis through phosphorylation and inactivation of GSK-3α and β (12,13). Akt may also play a role in insulin stimulation of glucose transport (12). In addition to its role in survival and glycogen synthesis, Akt is involved in cell cycle regulation by preventing GSK-3β-mediated phosphorylation and degradation of cyclin D1 (14) and by negatively regulating the cyclin dependent kinase inhibitors p27 Kip1 (15) and p21 Waf1/Cip1 (16). Akt also plays a critical role in cell growth by directly phosphorylating mTOR in a rapamycin-sensitive complex containing raptor (17). More importantly, Akt phosphorylates and inactivates tuberin (TSC2), an inhibitor of mTOR within the mTOR-raptor complex (18,19).
