Antibody with five example conjugation sites indicated. Each site represents a different conjugation strategy, 1) lysine 2) cysteine 3) carbohydrate 4) sequence modifications 5) protein-protein interactions.
Schematic summarizing the problem with species on species immunohistochemistry. The schematic is titled Species on Species Staining - The Problem and shows a cell membrane with a target protein and an endogenous IgG. A primary antibody is bound to the target and secondary antibodies conjugated with fluorophores are bound to both the primary antibody and the endogenous IgG.
