Dear Ray, Active Motif (Carlsbad, CA) has a reagent called "Chariot" that they claim can introduce proteins (including antibodies) into live cells. Tel. 877 222-9543 (toll free) or 760 431-1351. I have not tried it yet, but if anyone out there has, I would like to know if it really works. Best regards. Greetings, A recent discussion on the Confocal Listserv, concerning DAPI staining of viable cells, prompts me to send the following from a colleague: Is there a way to deliver antibodies, or their fragments, into viable cells? We have heard of using liposomes, but wondered if perhaps newer techniques have emerged. Thanks. Ray Hester Univ. of South Alabama Mobile, AL 36688 rhester@jaguar1.usouthal.edu Dr. Susan J.
