Total quenching of peroxidase and pseudoperoxidases, in RBC's

From:Carl Hobbs

 I used the original Glucose oxidase method  used by Eidie Heyderman(
remember her?) and found it OK but not superior to 3% H2O2, in pwax
sections. BUT addition of azide did, then , give complete quenching. So
azide is essential for blocking , not just preservative.
