The use of cellular assays in drug screening continues to grow with over 50% of primary screens using cell-based formats in 2006. The majority of cells used in the drug discovery industry are fresh, using ‘just in time’ batch processing from in-house facilities. This process could give rise to a number of issues, namely batch variation, scheduling of cell production and capacity management. We describe the use of microcarrier technology in combination with a suitably configured bioreactor to provide a rapid, robust and reproducible approach to cell production. Cells cultured in this way can be removed from beads, cryopreserved in a single HTS batch size format and maintain assay capacity. Learn More
