Genemed Synthesis Inc. (GSI) We offer quality services in the area of custom peptides, custom antibodies, and custom Oligo (DNA) synthesis. Oligo (20-50 bases) can be made, quality tested and shipped within 24-hrs.  Using more sophisticated DNA synthesizers and sequencers, we can synthesize genes up to 1-2 kb and verify by DNA sequencing. It is often quicker and less expansive to synthesize short genes than to clone them. Synthetic genes can also be cloned, expressed, and recombinant proteins purified for a variety of uses including antibody production.
