Fig. 3From: Cerenkov luminescence imaging is an effective preclinical tool for assessing colorectal cancer PD-L1 levels in vivoThe subcellular localization of PD-L1 protein in LoVo, LS174T, SW620, and RKO was determined by immunofluorescence staining with anti-PD-L1 antibody (green) and DAPI nuclear staining (blue). PD-L1 protein is mainly located on the plasma membrane among the four cell lines, and a small amount of PD-L1 expression was observed in the cytoplasmBack to article page
