Figure 2From: Generation and characterization of a SIVmac239 clone corrected at four suboptimal nucleotidesProtein analysis of SIVmac239Opt. Coomassie blue stain (a) and Western immunoblots (b) prepared from SDS-page gels of purified SIVmac239WT (239WT) or optimized SIVmac239 (239Opt). Western blots were generated by probing for gp41, gp120, and capsid p27.Back to article page
