How many donors are pooled to create the pooled human cell products?


When preparing Lonza’s pooled human cell products, at least three donors are pooled, but there is not an upper limit. Historically, Lonza has as many as six donors to create a single lot, but not higher. The vast majority of lots for Lonza’s pooled human cell products are pooled from three donors. These cells are pooled just prior vialing/cryopreservation. Each strain is handled individually until final trypsinization and then the cells are pooled and vialed.
