IHC image of S100 beta staining in a section of frozen normal human cerebral cortex performed on a Leica BOND^TM system using the standard protocol. The section was fixed in 10% paraformaldehyde (10 min) prior to staining. The section was incubated with ab16659, 1/5000 dilution, 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. The inset secondary-only control image is taken from an identical assay without primary antibody.

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.

Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 A-375 (human malignant melanoma cell line) cells labeling S100 beta with purified ab52642 at 1/100 dilution, followed by Goat anti rabbit IgG (Alexa Fluor^® 488) ab150077 secondary antibody at 1/500 dilution (green). The nuclear counter stain is DAPI (blue). The negative control is as follows;

S100 beta was immunoprecipitated from human fetal brain with purified ab52642 at 1/50 dilution. Western blot was performed from the immunoprecipitate using ab52642 and Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated was used as secondary antibody at 1/1000 dilution.

Blocking and dilution buffer and concentration: 5% NFDM/TBST.

S100 beta is present in CNV lesions.

A) S100 beta expression in a normal WT mouse retina. Strong immunoreactivity is present in the astrocytes (arrow). The position of the inner nuclear layer (INL) and outer nuclear layer (ONL) are indicted. Scale bar is 50 µm.

B) S100 beta expression in WT mouse retinal at day 7 post-laser treatment. S100B was detected in the outer plexiform layer (arrowheads). Strong S100 beta expression was detected at the site of CNV. Scale bar is 50 µm.

Immunofluorescent imaging of native and acellular human peripheral nerve sections stained for the axon protein Neurofilaments (NF200), the Schwann’s cell marker S100β (ab52642) and for the extracellular matrix proteins Laminin and Collagen IV. Sections were counterstained with DAPI to confirm the removal of the cell nuclei upon decellularization (scale bar: 100 μm).

Unpurified ab52642 staining S100 beta in human spiral ganglion tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraformaldehyde and blocked with 1% BSA for 30 minutes at room temperature; antigen retrieval was by heat mediation in citrate buffer, pH 6.0. Samples were incubated with primary antibody (1/200 in PBS-T + 1% BSA) for 12 hours. An Alexa Fluor^® 488-conjugated Donkey anti-rabbit IgG polyclonal (1/500) was used as the secondary antibody.
