From: Transmembrane and truncated (SEC) isoforms of MUC1 in the human endometrium and Fallopian tube
Immunofluorescence of primary cultured endometrial epithelial cells (A) and HEC1B cells (B-D) stained with antibodies against MUC1/SEC (A,B; Mab 7H10/5)), MUC1 tandem repeat domain (C; Mab BC3)) and a unique determinant in the ectodomain (D; Mab 232A/1). All fields contain confluent cells and the staining in each case is heterogeneous. The cell surface association of MUC1/SEC is particularly obvious in B.
