ABC Staining Kits include reagents for the avidin-biotin complex (ABC) technique, a highly sensitive method for immunohistochemical detection with biotinylated secondary antibodies.

• Very low background staining
• Rapid avidin-biotin interaction

Standard Kits containing only the two essential reagents (avidin and biotinylated HRP) can be used with nearly any species of biotinylated secondary antibody. The Ultra-sensitive ABC Peroxidase Staining Kits enable more dilute primary antibodies to be used while producing equal staining intensity. Ultra-sensitive kits are offered as a standard kit and as complete kits, which contain biotinylated secondary antibodies and appropriate blocking serum for use with mouse or rabbit antibodies.
