Opti-MEM I Reduced Serum Media
Gibco™ Opti-MEM™ I Reduced Serum Media is a modification of Eagle's Minimum Essential Media, buffered with HEPES and sodium bicarbonate, and supplemented with hypoxanthine, thymidine, sodium pyruvate, L-glutamine, trace elements, and growth factors.
Most cells grown in serum-supplemented media can be transferred to Opti-MEM media with a minimum of 50% reduction in serum.
Opti-MEM I Reduced Serum Media is ideal for use during cationic lipid transfections — especially Lipofectamine™ transfection reagents.

Need help selecting a transfection reagent?
Reagent-mediated transfection is a fast, simple, and reproducible means of introducing DNA, RNA, siRNA, or oligonucleotides into eukaryotic cells. Selecting a transfection reagent depends on the cell type, its adhesion properties, plating confluency, what you're transfecting, and other factors.
