Do you offer a protocol for titering virus in OptiPRO SFM?
For virus titering in OptiPRO SFM we recommend using Falcon or equivalent 96-well plates and plating cells at a concentration of 1 X 10^6/mL. If you are having trouble growing cells for virus titration in OptiPRO SFM in the 96-well plates, we suggest switching to the EMEM with 5%FBS or DMEM with 5% FBS.
Is there a recommended protocol for culturing cell lines in OptiPRO SFM that require sequential adaptation?
The sequential adaptation process is a multi-subculture of cells. We recommend the following passaging sequence:
• First passage: use 25% OptiPRO SFM:75% original stock medium
• Second passage: use 50% OptiPRO SFM:50% original stock medium
• Third passage: use 75% OptiPRO SFM:25% original stock medium
• Fourth and subsequent passages: use 100% OptiPRO SFM
