Avidin and streptavidin reagents are powerful tools to detect or purify biotinylated proteins, nucleic acids, and other macromolecules.
Vector Laboratories enzyme-conjugated avidin and streptavidin are produced with the highest specific activity enzymes in optimal ratios. Specific covalent linkages are chosen to provide stable, highly active conjugates.
This Horseradish peroxidase streptavidin preparation (HRP-Sav; SA-5014) is optimized for use in solid-phase assays such as ELISAs and blotting applications.
For horseradish peroxidase streptavidin (Sav-HRP) that is optimized for use in tissue/cell staining applications, see the following product:
