Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of CD-1 mice testes tissue sections labeling Notch2 with ab8926 at 1/100 dilution. CD-1 mice testes were fixed in 4% neutral phosphate buffered formalin at room temperature for 24 h and, after subsequent dehydration in ethanol, were embedded in paraffin. Tissue sections were stained by haematoxylin and identification of cell types was done through histology; The antigen retrieval step was performed in citrate buffer (10 mM, pH 6.0), Blocking was performed in PBS with 2% w/v bovine serum albumin for one hour at room temperature. Tissue sections were incubated overnight at 4°C with anti-Notch2 (ab8926). Positive immunostaining in brown color. Notch2 is expressed in germ cells entering meiosis.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human liver tissue sections labeling Notch2 with ab8926 at 1/500 dilution. No pre-treatment of sample was required. The image shows the localization of antibody as the precipitated red signal, with a hematoxylin purple nuclear counter stain.
