General description

These kits comprise universal reagents for use with primary antibodies in immunohistology, ELISA, and immunoblotting.
ExtrAvidin® is a unique form of avidin, available only from Sigma, that combines the high specificity and affinity of avidin for biotin with low non-specific binding at physiological pH. ExtrAvidin® peroxidase exhibits high sensitivity with low background.

Features and Benefits

  • Use in immunohistology, ELISA, and immunoblotting assays.
  • Affinity Isolated Antibodies have been adsorbed with human IgG and IgM to minimize cross-reactivity.
  • Biotinylated antibodies contain a spacer which improves accessibility for the ExtrAvidin® conjugates.


• 3 mL ExtrAvidin®-Peroxidase
• 3 mL Biotinylated Secondary Antibodies
