R3afts resemble cholesterol- and glycosphingolipid-enriched, liquid-ordered plasma membrane microdomains, showing resistance to nonionic detergents, and are involved in various cellular processes. in the present study, we have tested Surface antigens oil testing and lipopolysaccharide (LPS)-stimulated human peripheral blood monocytes for their detergent resistance (i.e. raft-association), by flow cytometry Constitutive (CD14, CD32, CD55), or LPS-induced (CD81) raft-association, and detergent solubility (i.e. exclusion of rafts) (CD71) of monocyte antigens in the presence of 0.01% Triton X-100 are clearly demonstrated. Flow cytometric detergent insolubility is a powerful tool for rapid screening the raft-association of monocyte antigens in a whole-blood assay. (c) 2006 International Society for Analytical Cytology.
