ALB and neoplasm: Notably, 65 kDa RABiT is anticipatedto have an 8 nm hydrodynamic diameter compared to 10–15 nmfor ∼150 kDa antibody-drug-conjugates and 80–120 nmfor clinical PEGylated liposomes and, therefore, may penetrate tumortissue more uniformly.55 Albumin accumulatesvia oncogene-driven macropinocytosis in multiple cancer types,39,56 and our experiments in mice indicated its tumor uptake can approachlevels achievable with some molecularly targeted methods.
