- Description
- Description: This SDRNR monoclonal antibody recognizes human and mouse AKT (also known as Protein Kinase B (PKB)) when phosphorylated on S473. AKT is a serine/threonine protein kinase that plays a key role in multiple cellular processes including metabolism, proliferation, apoptosis/survival, and migration. There are three homologous isoforms of AKT: AKT1, AKT2, and AKT3. AKT is activated by binding of its pleckstrin homology (PH) domain to membrane phospholipids and by phosphorylation. Phosphorylation of AKT at T308 by PDK1 and at S473 is required for full activation of this kinase. AKT promotes cell survival by inhibiting apoptosis via phosphorylation and inactivation of several targets including Bad, Foxo1, c-Raf, and caspase-9. Deregulation of AKT has been implicated as a major contributing factor in many types of cancer. AKT is negatively regulated by the phosphatase PTEN as well as by the chemical inhibitor LY294002. Specificity of this SDRNR clone was determined by ELISA, flow cytometry, and western blotting.

- Figure 1 N-803 increased the viability and proliferation of exPBNK with enhanced p-Stat3, p-Stat5, pAKT, p-p38MAPK and NK activating receptors. PBMNCs were stimulated with irradiated genetically modified K562-mbIL21-41BBL cells for 2-3 weeks. (A) Purified exPBNK cells were cultured in complete medium with 0.35 ng/mL (low) or 3.5 ng/mL (high) N-803 or molar equivalent dose of IgG for 3 days. NK viability and proliferation were monitored by MTS assays. The amount of 490 nm absorbance is directly proportional to the number of living exPBNK cells in the culture. The exPBNK cells with N-803 at 0.35 ng/mL or 3.5 ng/mL have significantly higher viability as compared with IgG or medium controls (p
