Chromogenic substrate method
WebChromogenic detection is an economical and far less labor intensive method for the detection of target protein during a Western blot protocol. Much like chemiluminescent detection, chromogenic detection uses a secondary antibody conjugated to a reporter enzyme that is either HRP or AP. WebFour main methods of indirect chromogenic detection are widely used today. The biotin-based methods use an avidin-biotin complex (ABC) or a labeled streptavidin-biotin …
