Immunocytochemistry/ Immunofluorescence - Anti-PMP70 antibody (AB3421)

Immunofluorescence analysis of PMP70 was performed using 70% confluent log phase A431 (Human epidermoid carcinoma cell line) cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 1 hour at room temperature. The cells were labeled with ab3421 at 5 μg/ml in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Goat anti-Rabbit IgG (H+L), Superclonal™ Recombinant Secondary Antibody, Alexa Fluor 488 at a dilution of 1 : 2000 for 45 minutes at room temperature (Panel a : green). Nuclei (Panel b : blue) were stained with ProLong™ Diamond Antifade Mountant with DAPI. F-actin (Panel c : red) was stained with Rhodamine Phalloidin. Panel d represents the merged image showing cytoplasmic (peroxisomal pattern) localization. Panel e represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

Knockdown of PMP70 was achieved by transfecting A431 (Human epidermoid carcinoma cell line) cells with PMP70 specific siRNA. Immunofluorescence analysis was performed on A-431 cells (untransfected, panel a,d), transfected with non-specific scrambled siRNA (panels b,e) and transfected with PMP70 specific siRNA (panel c,f). Cells were fixed, permeabilized, and labelled with PMP70 Rabbit Polyclonal Antibody (5 μg/ml), followed by Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, Alexa Fluor® 488 (1 : 2000). Nuclei (blue) were stained using ProLong™ Diamond Antifade Mountant with DAPI, and Rhodamine Phalloidin (1 : 300) was used for cytoskeletal F-actin (red) staining. Reduction of specific signal was observed upon siRNA mediated knockdown (panel c,f) confirming specificity of the antibody to PMP70 (green). The images were captured at 60X magnification.

Flow cytometry analysis of PMP70 in HEK-293T (Human epithelial cell line from embryonic kidney transformed with large T antigen) cells (green) compared to an isotype control (blue). Cells were harvested, adjusted to a concentration of 1-5x10⁶ cells/ml, fixed with 2% paraformaldehyde and washed with PBS. Cells were blocked with a 2% solution of BSA-PBS for 30 min at room temperature and incubated with ab3421 at a dilution of 0.5 ug/test for 60 min at room temperature. Cells were then incubated for 40 min at room temperature in the dark using a Goat anti-Rabbit IgG (H+L) Secondary Antibody, Alexa Fluor 488 and re-suspended in PBS for FACS analysis.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-PMP70 antibody (AB3421)

ab3421 (2µg/ml) staining PMP70 in human duodenum using an automated system (DAKO Autostainer Plus). Using this protocol there is apical cytoplasmic staining and staining of the endoplasmic reticulum in the epithelium.
Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer EDTA pH 9.0 in a DAKO PT Link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.

ICC/IF image of ab3421 stained human HeLa (Human epithelial adenocarcinoma cell line) cells. The cells were 4% PFA fixed (10 min) and then incubated in 1% BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab3421, 1 μg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor^® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor^® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue). This antibody also gave a positive IF result in Hek293, HepG2 and MCF7 cells.
