title: Fast chemiluminescent measurement of RNA polymerase activity based on photon counting technology.
abstract: A fast and simple assay for T7 RNA polymerase based upon chemiluminescent detection of the synthesized, digoxigenin-labeled RNA on a nylon membrane with anti-digoxigenin coupled alkaline phosphatase and CSPD as substrate is described. Activity of RNA polymerase is determined with high sensitivity by quantifying the emitted light of the microplate-formatted dot-blot membrane with a photon counting microplate luminometer and a specially designed filter adapter. The described method is one example for the application of this new adapter to measure luminescent membrane filters.
