Immunofluorescent staining of SH-SY5Y cells (fixed with 4% PFA and permeablized with TritonX 100) with purified ab108937 at a dilution of 1/100. An Alexa Fluor® 555 goat anti-rabbit antibody was used as the secondary at a dilution of 1/200. The panel on the right shows the DAPI counter-staining.

Overlay histogram showing SH-SY5Y cells fixed in 2% PFA and stained with purified ab108937 at a dilution of 1 in 30 (pink line). The secondary antibody used was FITC goat anti-rabbit at a dilution of 1 in 50. Rabbit monoclonal IgG was used as an isotype control.

Immunohistochemical staining of Hes1 in paraffin-embedded human placenta tissue with unpurified ab108937 at 1/250 dilution.

Immunohistochemical staining of paraffin embedded human brain with unpurified ab108937 at a working dilution of 1 in 90. The secondary antibody used is a HRP polymer for rabbit IgG. The sample is counter-stained with hematoxylin. Antigen retrieval was perfomed using Tris-EDTA buffer, pH 9.0.

Immunofluorescent staining of SH-SY5Y cells (fixed with 4% PFA and permeablized with TritonX 100) with unpurified ab108937 at a dilution of 1/40. An Alexa Fluor® 555 goat anti-rabbit antibody was used as the secondary at a dilution of 1/200. The panel on the right shows the DAPI counter-staining.

Overlay histogram showing SH-SY5Y cells stained with unpurified ab108937 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab108937, 1/100 dilution) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-rabbit IgG (H+L) (ab96899) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
