BACKGROUND Recent studies have shown that 3'-deoxy-3'-[(18)F] fluorothymidine ([(18)F]FLT)) uptake depends on endogenous tumour thymidine concentration. The purpose of this study was to investigate tumour thymidine concentrations and whether they correlated with [(18)F]FLT uptake across a broad spectrum of murine cancer models. A modified liquid(More)
A protein activity has been identified in extracts of coated vesicles that enables purified clathrin triskelions to reassemble in vitro into coat structures of uniform size. Coats formed in the presence of this preparation, regardless of the buffer system employed, are uniform in size with a mean diameter of 78 nm (+5 nm SD) and a sedimentation coefficient(More)
