Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-FOXP3 antibody [221D] - BSA and Azide free (ab255942)
Immunohistochemical analysis of paraffin-embedded human tonsil tissue labeling FOXP3 with ab253297 at 1/1000 dilution (1.514 µg/ml) followed by a ready to use secondary. Nuclear staining on the human tonsil. The section was incubated with ab253297 for 30 mins at room temperature. The immunostaining was performed on a Leica Biosystems BOND® RX instrument. Counterstained with Hematoxylin.
Secondary antibody only control: Secondary antibody is a ready to use secondary.
