Later, they used two monoclonal antibodies to the ectodomain of L1CAM (L1-11A and L1-14.10) and two to the C-terminal part of L1CAM (2C2 and 745H7), but neither the expression of every different antibody nor the cutoff value for positivity are explained—in 10 normal endometria and in 296 endometrial carcinomas, corresponding to 272 endometrioid adenocarcinomas, 20 serous carcinomas, and 4 clear cell carcinomas [21]. The gene discussed is L1CAM; the disease is serous adenocarcinoma.
