Gene expression correlates with protein expression.

Gene and protein expression of CD markers known to be differentially expressed during B-cell differentiation were compared between the MM cell line CAG (left panel) and the EBV-transformed B-lymphoblastoid line ARH-77 (right panel). In both panels, the 8 CD markers are listed in the left column of each panel. Flow cytometric analysis of protein expression is presented in the second column; the AD and AC values of gene expression, in the third and fourth columns. Note the strong expression of both the gene and protein for CD138 and CD38 in the CAG cells but the low expression in the ARH-77 cells. The opposite correlation is observed for the remaining markers.
