SignaTECT® Protein Kinase Assay System

DNA-PK activity measured in HeLa cell nuclear extract using the SignaTECT(R) DNA-PK Assay in the presence (circles) or absence (squares) of activator.These assays contain the proprietary SAM Biotin Capture Membrane. These streptavidin-coated membranes possess high binding capacity and high specificity characteristics, resulting lower backgrounds and higher signal-to-noise ratios compared to the traditional P81 phosphocellulose assays. The high binding capacity allows use of the SignaTECT® Systems for kinetic studies.

PDE-Glo™ Phosphodiesterase Assay

The PDE-Glo™ Assay using PDE V and a PDE inhibitor, zaprinast.PDEs have been implicated in a variety of diseases, such as erectile dysfunction, asthma, chronic obstructive pulmonary disease and learning and memory disorders. The availability of selective inhibitors for PDEs has paved the way to investigate their role in cellular and tissue pathologies. This luminescent, high-throughput screening method allows for identification of lead candidates for PDE inhibitors.
