At what passage do PromoCell supply the cell pellets?
The majority of PromoCell cell pellets (C-14**) are prepared 1 passage after thawing the cryopreserved cells. Examples: HUVEC and HUAEC correspond to P1 after thawing; therefore the pellets are frozen in P2. SMC or keratinocytes or epithelial cells correspond to P2 after thawing; therefore the pellets are frozen in P3. In contrast, our blood cells are cryopreserved directly after cell isolation. These pellets are prepared after thawing the cryovials with no further cultivation step.
