Caption: Gel electrophoresis used for protein analysis in the production of VaxSyn, an experimental AIDS vaccine. VaxSyn is based on a genetically- engineered, recombinant form of the HIV protein gp160, a precursor to one of HIV's outer surface proteins. Here, the scientist is loading recombinant protein samples onto the top of the gel. Application of an electric field causes the proteins to migrate differentially according to their size, and provides a means of identification. The vaccine is being developed by MicroGeneSys and is undergoing trials as a treatment of HIV-positive patients & as a potential vaccine against HIV infection.
