Immunocytochemistry/ Immunofluorescence - PARK7/DJ1 antibody (ab18257)

ICC/IF image of ab18257 stained human HeLa cells. The cells were methanol fixed (5 min) and incubated with the antibody (ab18257, 5µg/ml) for 1h at room temperature. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Image-iT^TM FX Signal Enhancer was used as the primary blocking agent, 5% BSA (in TBS-T) was used for all other blocking steps. DAPI was used to stain the cell nuclei (blue). Alexa Fluor® 594 phalloidin was used to label F-actin (red).

ab18257 staining PARK7/DJ1 in Human parathyroid. The paraffin embedded  tissue was incubated with ab18257 (1/22000 dilution) for 30 mins at room temperature. Antigen retrieval was performed by heat induction in citrate buffer pH 6. ab18257 was tested in a tissue microarray (TMA) containing a wide range of normal and cancer tissues as well as a cell microarray consisting of a range of commonly used, well characterised human cell lines.
