Figure 5From: Production and characterisation of monoclonal antibodies against RAI3 and its expression in human breast cancer Competitive RAI3 Immunohistochemistry on cancerous breast tissue. Immunohistochemical staining of cancerous breast tissue (A, B) in comparison to a competitive immunohistochemical approach (C, D). Strong staining of tumourous tissue was observed using a 1:50 dilution of anti-RAI3 Mab 24 2.3 (A, B). Staining is inhibited by pre-incubation of the antibody with 200-fold molar excess of recombinant RAI3 protein (C, D). Magnifications: A, C: 200×; B, D: 400×.Back to article page
