Using polymerization marking method, HRP is conjugated with secondary antibody to form huge octopus-like molecule antibody-enzyme polymer. Thus, secondary antibody and third antibody in traditional method can be replaced by the enzyme polymer. And the enzyme polymer is specially fit for immunohistochemistry analyses for its powerful nature of amplifying signal and permeating tissues and cells. Comparing with troditional SABC kits (StreptAvidin-Biotin Complex), SV Kits possess superiorities of high speed, high sensitivity, low background and ease-of-use. Kit Components: 1. 5% BSA Blocking Reagent: 10ml, for blocking tissue sections. 2. Secondary Antibody (polymerization HRP conjugated anti-goat IgG): 10ml 3. 3%H2O2: 10ml. Applications: Suitable for use in Immunohistochemistry (paraffin), Immunohistochemistry (frozen), Immunocytochemistry. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher.
