Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - HRP Anti-GST3 / GST pi antibody [EPR8263] (AB202930)

IHC image of GST3/GST pi staining in a section of formalin-fixed paraffin-embedded normal human placenta tissue*, performed on a Leica BOND^TM. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab202930, 1/625 dilution, for 15 mins at room temperature. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset negative 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.

Western blot - HRP Anti-GST3 / GST pi antibody [EPR8263] (AB202930)

ab202930 was shown to specifically react with GST3 / GST pi in wild-type HAP1 cells as signal was lost in GSTP1 (GST3 / GST pi) knockout cells. Wild-type and GSTP1 (GST3 / GST pi) knockout samples were subjected to SDS-PAGE. ab202930 and ab184095 (Mouse monoclonal [mAbcam 9484] to GAPDH - Loading Control (Alexa Fluor^® 680) loading control) were incubated overnight at 4°C at 1/5000 dilution and 1/1000 dilution respectively. The loading control was imaged using the Licor Odyssey CLx prior to blots being developed with ECL technique.

Western blot - HRP Anti-GST3 / GST pi antibody [EPR8263] (AB202930)

This blot was produced using a 4-12% Bis-tris gel under the MES buffer system. The gel was run at 200V for 35 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin before being incubated with ab202930 overnight at 4°C. Antibody binding was visualised using ECL development solution ab133406.
