ARC ‐ assay ready cells have been developed to release you from preparatory cell culture work and to provide you with a better flexibility to schedule your experiments. ARCs are cryopreserved at a highly functional state and can be used instantly after thawing like other reagents you are using in your assay. There is no need to further expand or passage the cells before. Simply dispense the recovered ARCs into an assay plate and proceed as usual. The high consistency of the pre‐validated cells helps to increase the reproducibility and reliability of any cell based assay. ARCs of different cell lines are provided at 10 million cellls per vial ready‐to‐use with recovery buffer and assay medium and can be applid for various types of assays.
