Objective: To verify whether hot PBS washing after the enzymatic reaction between tyramine and horseradish peroxidase can improve the sensitivity and specificity of catalyzed signal amplification. Methods: Using 7 different types of primary antibodies and 2 tomor microarray system, we carried out EnVision, LSAB, Standard CSA, and modified CSA staining sod compared their sensitivities and specificities. Results: The modified CSA method was the moat sensitive one among the 4 methods.
