Anti-FOXP3 antibody [mAbcam 22510] (ab22510)

IHC image of FOXP3 staining in a section of formalin-fixed paraffin-embedded normal human tonsil* performed on a Leica BOND^TM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with EDTA buffer (pH9, epitope retrieval solution 2) for 20mins. The section was then incubated with ab22510, 10ug/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

ab22510 staining cultured rat OCPs by ICC/IF. The cultured cells were fixed with 4% paraformaldehyde for 5 minutes, permeabilized 30 minutes with 0.1% PBS-0.3% TritonX and blocked with 10% donkey serum in 0.1% PBS-0.3% TritonX for 30 minutes at 24°C. The cultured cells were then stained with ab22510 at 1/1000 in 0.3% TritonX with 0.1% PBS and 10% donkey serum for 4h at 24°C. An Alexa Fluro 568 donkey anti-mouse polyclonal antibody at 1/1000 was used as the secondary antibody. Nuclei were stained with 1.43µM Hoechst and can be observed in blue.

Clone mAbcam 22510 used to stain formalin-fixed paraffin-embedded sections of human tonsil. Antigens were heat retrieved with pH9 Tris-EDTA buffer.

These images were produced with neat supernatant produced with this clone (the stock of this antibody is purified from supernatant).
