ABC–NiDAB |
1 |
Most sensitive; strongest staining at lowest concentration |
Direct tagged secondary antibody |
20- to 100-fold higher concentration of primary antibody to get maximal staining |
Least sensitive of the fluorescence methods |
ABC–streptavidin fluorescence |
10- to 30-fold higher concentration of primary needed to obtain maximal staining |
Approximately 3 times more sensitive than the direct tagged secondary fluorescence |
Biotinylated TSA-amplified streptavidin fluorescence |
2-fold higher concentration of primary antibody yields equal sensitivity to the NiDAB method |
Most sensitive of the fluorescence methods |
