Fig. 3From: Interleukin-6 trans-signaling increases the expression of carcinoembryonic antigen-related cell adhesion molecules 5 and 6 in colorectal cancer cellsMost colon cell lines express CEACAM5 and CEACAM6 proteins on their surface. a, The CEACAM5/6 expression of different colorectal cancer cell lines (HT29p, HT29c) and normal mucosa-derived colon cell lines (CSC1, NCM460) was analyzed by flow cytometry using specific antibodies (grey) or an unspecific isotype control (white). The amount of positive cells (b) as well as the difference in the mean fluorescence intensity (dMean) between the specific staining and the isotype control (c) was analyzedBack to article page
