H1299 (human lung epithelial-like adenocarcinoma line) cells, Hela (human cervical carcinoma cell line) cells, and BEAS2B (immortalized non-tumorigenic lung cancer cell line) cells were used as controls for antibody reactivity for Mertk, Axl, and Tyro3, respectively, based on previous observations in our laboratory. The gene discussed is TYRO3; the disease is cervical carcinoma.
