ABSTRACT
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 (CSA).Methods:
Using 7 different types of primary antibodies and 2 tumor microarray system, we carried out En Vision, LSAB, Standard CSA, and modified CSA staining and compared their sensitivities and specificities.Results:
The modified CSA method was the most sensitive one among the 4 methods, followed by standard CSA, En Vision, and LsAB method. The sensitivity of modified CSA method was 2-3 times higher than that of standard CSA. The 4 methods had similar background staining and had exact localization of cells.Conclusion:
The modified CSA is more stable and sensitive than traditional CSA staining method.
