Thermo Scientific Pierce ABC Staining Kits include reagents for the avidin-biotin complex (ABC) technique, a highly sensitive method for immunohistochemical detection with biotinylated secondary antibodies.
Pierce ABC Staining Kits are highly sensitive, produce very low background staining and have rapid avidin-biotin interactions. Standard Kits contain 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 are approximately five times more sensitive than the regular-senstivity kit, enabling 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 block serum for use with mouse or rabbit antibodies, respectively.
