Catalyzed Signal Amplification, or CSA as it is called by DAKO, is a method for adding successive layers of biotin to a sample hybridized with biotinylated probes through a catalytic process, rather than the more common sandwiching of layers of biotin/avidin molecules. By using catalysis, the potential for amplification is ...
