Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Pax2 antibody [EP3251] (AB79389)

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human renal cancer tissue labelling Pax2 with ab79389 at 1/100 dilution. Positive staining on human renal cancer. The section was incubated with ab79389 for 30 minutes at room temperature. Slides were incubated with 3% Hydrogen Peroxide for 10 mins at room temperature after secondary antibody incubation to reduce the background. The immunostaining was performed on a Leica Biosystems BOND^® RX instrument. A Rabbit specific IHC polymer detection kit HRP/DAB (ab209101) was used as the secondary antibody (Ready-to-use). Counterstained with hematoxylin. Negative control using PBS instead of primary antibody.

Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution 2) for 20 mins.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Pax2 antibody [EP3251] (AB79389)

Immunohistochemical analysis of Pax2 expression in tissue sections of human benign nevi and malignant melanoma using ab79389 at 1/100 dilution. All specimens were fixed in 4% formaline (pH 7.4), embedded in paraffin followed by cutting with a microtome (3 µm thickness). The slides were deparaffinized in xylol for 20 minutes and then rehydrated in descending series of ethanol (100%, 100%, 96%, 96%, 70%, and 70%). For antigen retrieval the slides were boiled in citrate buffer (pH 6.0) for 40 min, and then allowed to cool down for 15 min. After washing with PBS buffer the endogenous peroxidase was blocked with H2O2 for 15 min at room temperature. After washing in PBS the slides were incubated with the antibody against PAX2 (dilution 1/100) for 60 min at room temperature and washed in PBS again. The secondary antibody was incubated for 20 min at room temperature and after washing the slides in PBS the biotin streptavidine label was incubated for 20 min at room temperature. A detection kit including horseradish peroxidase and diaminobenzidine as chromogene was applied for 5 min. Counterstaining was performed with hematoxilin for 6 min. (A) In normal sweat glands, Pax2 is expressed in gland epithelial cells (black arrows) while intermingled stromal cells only show very weak or absent nuclear Pax2 expression (green arrow) Bar represents 100 µm. (B, C) Normal appearing epidermal cell layers adjacent to (B, bar represent 100 µm) nevi or (C, bar represent 200 µm) malignant melanoma show a differentially Pax2 expression with strongest Pax2 levels in germinal basal cell layers (black arrows) decreasing in higher differentiated keratinocytes and finally being absent in corneocytes (green arrows). (D) Malignant melanoma cells - heterogeneous nuclear Pax2 expression. Strongest expression in large atypical nuclei with prominent nucleoli (black arrows). (E, F) Pax2 expression in intradermal nevi was heterogeneous and did not correlate with histological features.

Immunocytochemistry/ Immunofluorescence - Anti-Pax2 antibody [EP3251] (AB79389)

Pax2 is expressed in melanocytes of benign nevi (A) and melanoma cells of patients with malignant melanoma (B). Cells were grown on coverslips and fixed with 4% paraformaldehyde/PBS. After washing the cells with PBS, cells were permeabilized and blocked with 0.1% Triton X-100/PBS containing 5% BSA. Pax2 (green) was examined by immunofluorescent analysis using ab79389 at 1/100 dilution (incubated for 1 hour at room temperature). Following 3 times washing, bound antibodies were deteced by Alexa 488 conjugated goat anti-mouse or Cy3 conjugated goat anti-mouse secondary antibodies. Following PBS-washing nuclei were stained with 4'6-diamidino-2-phenylindole (DAPI, Blue) and cells were mounted in Fluoromount-G™ and examined by fluorescence microscopy. White arrows in the higher magnified insets indicate PAX2 expression in nucleoli of melanocytes of benign nevi (A), yellow arrows in the higher magnified insets specify PAX2 expression in nucleoli of melanoma cells (B).
