For increased sensitivity with biotin-labeled detection antibodies in sandwich ELISA.
Ultra Streptavidin-HRP consists of streptavidin protein that is covalently conjugated to horseradish peroxidase (HRP) enzyme. Streptavidin binds to biotin and the conjugated HRP provides a high level of activity for detection using an appropriate substrate system.
