Figure 1From: Characterization of humoral responses to soluble trimeric HIV gp140 from a clade A Ugandan field isolateAnalysis of the gp140 94UG018 protein. (A) The trimeric form of recombinant gp140 protein was verified and purified by a size-exclusion chromatography. (B) Fractions corresponding to the gp140 trimer were pooled and analyzed by Coomassie stained denaturing SDS PAGE to confirm the purity of the product.Back to article page
