Figure 6From: Role of the long cytoplasmic domain of the SIV Env glycoprotein in early and late stages of infectionLipid raft association of the SIV Env protein. The interaction of the Env protein of SIVmac239 (A), SIVmac239-EnvT (B), and SIVmac239-EnvC787S (C) with lipid rafts was analyzed in a discontinuous sucrose gradient. CEMx174 (A, B, C) cells were infected with 2 pfu/cell of respective vaccinia recombinant viruses. The infected cells were labeled with 35S-methionine/cysteine, disrupted by detergent TX-100 and a discontinuous sucrose gradient of 5 to 30% sucrose was used to obtain 11 fractions as described in Methods.Back to article page
