Lonza Accelerated Clonal Cell Line Constructions

March 10,2009 Basel, Switzerland

Lonza scientists have developed a new cell line construction process that delivers cGMP material in 14 months from the receipt of DNA sequence, using rapid methods for generating clonal cell lines. Called “One-Step,” this customer-tailored cell line construction process uses chemically defined, non-animal origin components. It includes cell line stability testing, stringent selection to isolate high-yielding cell lines, procedures and datapack to support monoclonality, regulatory support, and the same Lonza quality customers trust.

“This new clonal cell line construction process is a breakthrough that gives customers high-quality results faster than ever before” said Allison Vernon, Head of Lonza Biopharmaceuticals Mammalian R&D Services. “The One-Step program, as well as Lonza’s other cell line construction services, offers customers flexible solutions that meet their immediate needs.”

Leveraging the strengths of Lonza’s proprietary GS Gene Expression SystemTM, the 14-month One-Step program can be further tailored to suit customers’ project and timeline requirements. Lonza also offers cGMP material from uncloned cell lines for early phase use in 11 months from receipt of DNA sequence and material for proof-of-concept studies from pooled transfectants in 4 months.
