IHC image of MMP3 staining in a section of formalin-fixed paraffin-embedded human colon adenocarcinoma*. The section was pre-treated using pressure cooker heat mediated antigen retrieval with sodium citrate buffer (pH6) for 30mins, and incubated overnight at +4°C with ab194716 at a working dilution of 1/500. DAB was used as the chromogen (ab103723), diluted 1/100 and incubated for 10min at room temperature. The section was counterstained with haematoxylin and mounted with DPX. The inset negative control image is taken from an identical assay without primary antibody.For other IHC staining systems (automated and manual) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.*Tissue obtained from the Human Research Tissue Bank, supported by the NIHR Cambridge Biomedical Research Centre
