New Products: Apr 2, 2009


Invitrogen, a division of Life Technologies, this week introduced the Gibco OptiCho Protein Express Kit for developing serum-free, stable cell lines for biotherapeutic development.

The kit is the first of its kind to provide cells banked under cGMP conditions, the company said in a statement.

The kit incorporates all reagents, protocols, and documentation required to go from gene to stable cell clones "expressing the protein of interest within a completely serum-free environment," Invitrogen said.

The kit is available for use in research but laboratories interested in pursuing regulatory filings and in need of a documentation package can purchase a commercial use license for a one-time fee, and with no maintenance fees or royalties required, the company added.
