Description: This LN-1 monoclonal antibody reacts with human CD75, a cell surface carbohydrate determinant produced by alpha-2,6-sialytransferase. CD75 is expressed predominantly on mature B cells in peripheral blood and germinal centers, as well as several B cell lines (e.g., Raji, Ramos). CD75 is also expressed on non-immune tissues such as breast, prostate, colon, liver, and kidney. Reports demonstrate that CD75 is a ligand of CD22.
Studies have shown that, depending on fixation and tissue processing, the LN-1 antibody also recognizes astrocytes and microglia in the human brain.
