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.

Western blot of human MDA-MB-231 breast carcinoma (lane 1), PC-3 prostate adenocarcinoma (lane 2), A549 lung carcinoma (lane 3), NCI-H1915 lung carcinoma (lane 4), and A431 epidermoid carcinoma (lane 5). The blot was probed with mouse monoclonal anti-Axl (AM0471) at 1:1000.

Immunocytochemical labeling of Axl in aldehyde fixed human MDAMB-231 breast carcinoma cells. The cells were labeled with mouse monoclonal anti-Axl (AM0471). The antibody was detected using goat anti-mouse DyLight® 594.

Representative Standard Curve using mouse monoclonal anti-Axl (AM0471) for ELISA capture of human recombinant Axl extracellular region with a His-tag. Captured protein was detected by suitable anti-His-tag antibody followed by appropriate secondary antibody HRP conjugate.

Clone (M047) was generated from a recombinant protein that included the extracellular region of human Axl protein.

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.

*All molecular weights (MW) are confirmed by comparison to Bio-Rad Rainbow Markers and to western blot mobilities of known proteins with similar MW.
