Anti-Avidin/Streptavidin Reagents

Amplify avidin and streptavidin signals in a range of applications

Use Anti-Avidin or Anti-Streptavidin amplification reagents to increase sensitivity in streptavidin or avidin/biotin detection systems. Anti-avidin does not bind streptavidin, and anti-streptavidin does not recognize avidin. Avidin or streptavidin amplification reagents can amplify signals in many applications, including:

  • Immunohistochemistry 
  • In situ hybridization
  • Microarray assays
  • ELISAs
  • Blots

Vector offers anti-avidin and anti-streptavidin antibodies in biotinylated, fluorophore-conjugated, or unconjugated formats. The biotinylated formats are unique in that they allow binding to streptavidin or avidin through both of their antigen-binding sites and the covalently-attached biotin residues.
