Ultrapure, unconjugated reagents for purification and detection of biotinylated macromolecules
Avidin and streptavidin are proteins that bind biotin irreversibly, each with four biotin-binding sites. Use these ultrapure, inconjugated forms of avidin and streptavidin to detect antigens, glycoconjugates, and nucleic acids in a range of research applications.
- Choose Avidin D for detection of biotinylated proteins in immunohistochemistry, immunocytochemistry, immunofluorescence, Elispot, and ELISAs
- Choose Avidin DN for detection of biotin-labeled DNA or RNA probes for in situ or nitrocellulose hybridization techniques
- Choose Streptavidin for solid-phase assays and immunohistochemical applications when sequential addition of reagents (sandwich technique) is employed as well as in subtractive hybridization procedures
