instaCELL IL-2 potency assay kit
The proliferation of cells which depend on the presence of cytokines is a very sensitive and robust method to determine the potency of recombinant interleukin-2 (IL-2) formulations. CTLL-2, a mouse cytotoxic T-cell line, fully arrest in the absence of IL-2 and resumes to proliferate in a dose-dependent manner when Il-2 is added.
The instaCELL IL-2 potency assay kit includes pre-arrested cryopreserved CTLL-2 which can be used in an IL-2 proliferation assay instantly like a reagent, without prior cultivation or starving. Besides the cells the validated kit also includes media, reagents, reference standard, and a 96-well plate.
