SARS-CoV S palmitoylation is necessary for partitioning into detergent-resistant membranes. At 24 h post-transfection, detergent-resistant membranes (DRMs) were extracted from HEK293T cells expressing SARS-CoV S or SPN using cold Triton. DRMs were isolated using discontinuous density ultracentrifugation, and fractions were collected from the top. S protein was identified by Western blotting (upper and middle panels) and DRMs were identified using HRP-cholera toxin B, which binds ganglioside GM1 (bottom panel). A representative image of 3 independent experiments is shown.
