Pre-adsorbed antibodies

Pre-adsorbed (cross-adsorbed) secondary antibodies have gone through an extra purification step to eliminate antibodies that may cross-react with other species, minimizing non-specific binding and high background. We offer more than 1,000 pre-adsorbed secondaries conjugated to diverse molecules including HRP and Alexa Fluor® dyes.
