For the cellular investigation of proliferation, cytotoxicity and certain cell functions, Lonza offers various assays. With unprecedented speed and high sensitivity, ViaLight assays provide an alternative to radioactive test methods for the experimental study of proliferation and cell death. ToxiLight assays are characterized by their non-destructive method. The adenylate kinase released from damaged cells is measured in these assays. With regard to cell function, we offer assays for the determination of phosphodiesterases (PDELight) and cyclases (PPiLight). In addition, you will find various assays for the determination of various cellular functions of primary cells and cell lines, e.g. functions of the lipid metabolism and bone structure.
