Elements of antibody validation for immunofluorescence including (A) representative images showing CD40 expression in positive cell lines SKBR3 and THP-1 (DAPI in blue, CD40 in red), (B) representative images showing lack of CD40 expression in negative cell lines JURKAT and MOLT-4, (C) regression between EPR20540 and a different CD40 antibody clone, D8W3N, and (D) regression of EPR20540 staining between 2 operators
