AlkPhos Direct Labeling and Detection Systems are based on the rapid, direct labeling of DNA or RNA probes with thermostable alkaline phosphatase. CDP-Star detection reagent allows for chemiluminescent detection of Alkaline Phosphatase labelled nucleic acids

Each system includes the following reagents, sufficient for 25 or 50 labeling reactions and detection of 2500 cm² or 5000 cm² membrane (depending on product ordered): labeling reagent, crosslinker, control DNA, reaction buffer, hybridization buffer, blocking agent, CDP-Star or ECF detection reagents.
