Figure 7. sCLU is expressed in CD68+ mature macrophages but not in CD33+ immature myeloid cells in invasive ductal carcinoma.
Immunohistochemical fluorescent analysis of a paraffin-embedded section of invasive ductal carcinoma tissue was conducted by dual staining with primary rabbit anti-human CD68 and mouse anti–human sCLU, or rabbit anti-human CD33 and mouse anti-human sCLU, followed by anti-mouse Alexa-647 and anti-rabbit Alexa-488.
