Abstract
Tyramide signal amplification (TSA) is an enzyme-mediated method to enhance the immunohistochemical detection of protein, nucleic acid, or other molecules in situ.Here we describe immunofluorescent detection of a low-abundance cytokine receptor, interleukin-17 receptor B (IL17RB) in U2OS cells, using tyramide signal amplification. In addition, we present a tyramide signal amplification compatible double-color immunostaining protocol using primary antibodies from thesame host species. Those applications allow detection of cellular proteins with enhanced sensitivity and add flexibility on primary antibody selection in double- or multicolor immunofluorescence staining assays.
