Mike, the comparison to antisense is IMO right on target. For therapeutic applications one has to worry about delivery issues; doesn't Sangamo have some sort of collaboration with a "protein delivery" specialist? From the S-1:
<boiler plate> Also, delivery of ZFP transcription factors into cells in these and other environments is limited by a number of technical challenges, which we may be unable to surmount.
<TGEN connection> In order to regulate a gene, the ZFP transcription factor must be delivered to a cell. We have licensed gene transfer technology from Targeted Genetics, Inc. for use with our Universal GeneTools in pharmaceutical discovery. We are evaluating this and other technologies for the delivery of ZFPs into cells.
<SAB member> George N. ("Joe") Cox, Ph.D. is President and Chief Scientific Officer of Bolder Biotech, a protein delivery biotechnology company. Dr. Cox was Vice President, Research and Development at Sangamo from March 1995 to June 1998. He spent the previous 12 years of his career at Synergen, Inc., in various positions including Group Leader, Discovery Research, Chairman of Synergen's science counsel, Director of Animal Health Care, and Senior Scientist.
