Vector Laboratories offers a comprehensive range of Avidin/Biotinylated Reagents designed to enhance protein detection and visualization across various applications, including immunohistochemistry (IHC), in situ hybridization (ISH), enzyme-linked immunosorbent assays (ELISA), and Western blotting. These reagents leverage the strong affinity between biotin and avidin/streptavidin to provide sensitive and specific detection methods.
Biotinylated Reagents—These are biomolecules, such as antibodies or proteins, conjugated to biotin, facilitating their detection through avidin or streptavidin binding.
Enzyme-Conjugated Avidin/Biotin Reagents—These reagents are conjugated to enzymes like horseradish peroxidase (HRP) or alkaline phosphatase (AP), enabling chromogenic or chemiluminescent detection.
