Objective:
To compare the performance of a modified PAS staining, traditional PAS staining, Lyon's PAS staining, and Tsunahico Watanabe staining for staining sections of renal biopsy tissue.
Methods:
The sections of the renal biopsy tissue were stained with the 4 methods and their staining performance was compared.
Results:
The modified PAS staining method produced a better contrast and a higher resolution and showed a greater stability after repeated use than the other 3 methods for staining the renal tissue sections (P<0.05).
Conclusion:
The modified PAS staining method shows a better applicability than the other 3 PAS methods for staining sections of renal biopsy tissue.
