NF1 Antibody in Immunofluorescence (IF) — Immunofluorescence analysis of Neurofibromin was done on 70% confluent log phase SH-SY5Y cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with Neurofibromin (McNFn27b) Mouse Monoclonal Antibody (Product # MA1-085) at 2 µg/mL in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A28175) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d is a merged image showing punctate cytoplasmic localization. Panel e is a no primary antibody control. The images were captured at 60X magnification.

NF1 Antibody in Immunofluorescence (IF) — Immunofluorescent analysis of Neurofibromin in NIH-3T3 cells. Cells were grown on chamber slides and fixed with formaldehyde prior to staining. Cells were probed without (control) or with a Neurofibromin monoclonal antibody (Product # MA1-085) at a dilution of 1:20 overnight at 4 C, washed with PBS and incubated with a DyLight-488 conjugated secondary antibody (Product # 35503). Neurofibromin staining (green), F-Actin staining with Phalloidin (red) and nuclei with DAPI (blue) is shown. Images were taken at 60X magnification.

NF1 Antibody in Immunofluorescence (IF) — Immunofluorescent analysis of Neurofibromin in Hela cells. Cells were grown on chamber slides and fixed with formaldehyde prior to staining. Cells were probed without (control) or with a Neurofibromin monoclonal antibody (Product # MA1-085) at a dilution of 1:20 overnight at 4 C, washed with PBS and incubated with a DyLight-488 conjugated secondary antibody (Product # 35503). Neurofibromin staining (green), F-Actin staining with Phalloidin (red) and nuclei with DAPI (blue) is shown. Images were taken at 60X magnification.

NF1 Antibody in Immunofluorescence (IF) — Immunofluorescent analysis of Neurofibromin in U251 cells. Cells were grown on chamber slides and fixed with formaldehyde prior to staining. Cells were probed without (control) or with a Neurofibromin monoclonal antibody (Product # MA1-085) at a dilution of 1:20 overnight at 4 C, washed with PBS and incubated with a DyLight-488 conjugated secondary antibody (Product # 35503). Neurofibromin staining (green), F-Actin staining with Phalloidin (red) and nuclei with DAPI (blue) is shown. Images were taken at 60X magnification.

NF1 Antibody in Immunohistochemistry (IHC) — Immunohistochemistry was performed on cancer biopsies of deparaffinized Human breast carcinoma tissue. To expose target proteins, heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer, microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature and probed with a Neurofibromin monoclonal antibody (Product # MA1-085) at a dilution of 1:20 or without primary antibody (negative control) overnight at 4°C in a humidified chamber. Tissues were washed with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP, followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.

NF1 Antibody in Immunohistochemistry (IHC) — Immunohistochemistry was performed on normal biopsies of deparaffinized Human stomach tissue. To expose target proteins, heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer, microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature and probed with a Neurofibromin monoclonal antibody (Product # MA1-085) at a dilution of 1:20 or without primary antibody (negative control) overnight at 4°C in a humidified chamber.

Product Specific Information

MA1-085 detects neurofibromin in human, rat, and mouse cells.

MA1-085 has been successfully used in Western blot, and immunohistochemistry procedures. By Western blot, this antibody detects a ~240-260 kDa protein.

The MA1-085 immunogen is a synthetic peptide corresponding to the N-terminal residues 27-41 of human neurofibromin.

Target Information

Neurofibromin is a member of the GTPase-activating (GAP) class of proteins. These proteins enhance the GTPase activity of signaling G-Proteins like Ras. The NF1 gene is also classified as a tumor suppressor gene, and many studies have shown that mutations at the NF1 locus produce neurofibromas, rhabdomyosarcomas, leimyosarcomas, mental retardation and memory deficiency. Neurofibromin has also been associated with the intermediated filaments of the cytoskeleton. NF1 is expressed at its highest levels during periods of desmosome formation and mutations of NF1 produce variable cell sizes and morphologies.
