General Information

Biological Significance Three different Streptavidin-PolyHRP (SA-PolyHRP) conjugates have made a product line of universal reagents currently available for ultrasensitive detection in ELISA and related assay methods. SA-PolyHRP conjugates are built up from on an average five identical HRP homopolymer blocks chemically coupled to multiple streptavidin molecules distributed mainly on their outer surface. The estimated average number of HRP monomer molecules in SA-PolyHRP20 conjugate is 100 (20 X 5), in SA-PolyHRP40 - 200 (40 X 5) and in SA-PolyHRP80 - 400 (80 X 5). Thus, PolyHRP brings in reaction with substrate development system much larger number of enzyme label molecules (per one bound analyte molecule) than conventional conjugates do.
