Biotin (Long Arm) Maleimide is designed for biotinylating proteins, nucleic acids, or other molecules containing one or more thiol groups. It reacts under mild acid or neutral pH conditions with free sulfhydryl groups such as those of cysteine residues or sulfhydryls introduced chemically into proteins or other macromolecules. A 6-aminohexanoate spacer arm between the maleimide group and biotin reduces the possibility of steric hindrance and ensures that the biotin is fully accessible to avidin or streptavidin detection systems. The extraordinary affinity of avidin and streptavidin to biotin and the many biotin-avidin/streptavidin systems available make the biotin label ideal for a variety of applications including in situ hybridization, blotting, and affinity binding.
Streptavidin Poly-HRP Conjugate is streptavidin biotin-binding protein that is conjugated with polymers of horseradish peroxidase, enabling signal amplification and detection of biotinylated antibodies for IHC and other methods. This poly-HRP conjugate is designed to deliver the highest sensitivity and low background in immunoassays where sample volume is limited or when the target molecule is present at low levels. 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.
