DiI labelled human low densitiy lipoprotein has been used for monitoring Ac-LDL uptake by monocytes/ macrophages in conjunction with excess unlabelled Ac-LDL 5685-3404 (Rahman et al. 2008).
Sample lots of DiI labelled human low densitiy lipoprotein are individually evaluated for the labelling of human skin fibroblasts or P-388D cells grown in lipoprotein deficient medium for 48 hours.
Purified from human serum - liquid
Purified LDL is labelled with the fluorescent probe Dil (1,1'-dioctadecyl-3,3,3',3'-tetramethyl-indocarbocyanine perchlorate). The resultant product is then dialysed against 0.15 M NaCl, 0.05 M TRIS (pH 7.4) and 0.3 mM EDTA, sterilised by filtration and aseptically packaged.
