Stratagene of La Jolla, Calif. http://www.stratagene.com, recently introduced its new Biotrek reagent which shuttles whole proteins into cells. The protein of interest is mixed with a lipid carrier to form noncovalent complexes, which then attach to negatively charged surfaces of the plasma membrane and enter the cell via fusion or endocytosis. Once inside, the complexes disassemble rapidly, releasing active protein into the cell.
