Axl/UFO (Extracellular region) Antibody

The Axl/UFO receptor tyrosine kinase (RTKs) family includes Axl/UFO/Tyro7, Sky/Tyro3, and c-Mer/Tyro12. These RTKs have a conserved intracellular tyrosine kinase domain and extracellular domains that include immunoglobulin-like and fibronectin-type moieties similar to those found in cell adhesion molecules. The ligand for these receptors is the vitamin Kdependent protein growth-arrest-specific 6 (Gas6), which is structurally related to the protein S anticoagulation factor. Upon binding to its receptor, Gas6 activates phosphatidylinositol 3- kinase (PI3K) and its downstream targets Akt and S6K, as well as NF-κB. Axl is overexpressed in several cancers, including breast, lung, liver, colon, gastric, ovarian, pancreatic, and glioblastoma. The Axl/Gas6 signalling pathway has been shown to drive cancer cell survival, proliferation, migration and invasion, and several therapeutic strategies are being developed to regulate Axl cell signaling.

Clone M047 mouse monoclonal antibody detects a 140 kDa* protein on SDS-PAGE "Native" or denatured immunoblots of human A549, NCI-H1915, and MDA-MB-231 carcinomas. The antibody detects Axl in membranes and cytoplasm in MDA-MB-231 cell after immunocytochemical labeling. The antibody works for western blot, immunoprecipitation, immunocytochemistry, and ELISA capture.
