c-Fos Antibody

Immunocytochemistry/ Immunofluorescence: c-Fos Antibody [NBP2-50057]

Immunocytochemistry/Immunofluorescence: c-Fos Antibody [NBP2-50057] - Analysis of HeLa cells stained with rabbit pAb to c-FOS, NBP2-50057, dilution 1:5,000 in red, and mouse mAb to tubulin, dilution 1:10,000, in green. The blue is DAPI staining of nuclear DNA. HeLa cells were kept in fetal bovine serum (FBS) free media for 36 hours. Then the cells were treated with PBS (A), as a control, or stimulated with 20% FBS (B) for 30 min. c-FOS antibody labels only the nuclei of stimulated cells. Mouse hippocampus (C) or olfactory bulb sections (D) stained with NBP2-50057, dilution 1:20,000 in red, and mouse mAb to NF-L, dilution 1:5,000, in green. The blue is DAPI staining of nuclear DNA. Following transcardial perfusion of mouse with 4% paraformaldehyde, brain was post fixed for 24 hours, cut to 45uM, and free-floating sections were stained with above antibodies. The c-FOS antibody stains only nuclei of spontaneously active neurons. NF-L is expressed in axons of neuronal cells.

Western Blot: c-Fos Antibody [NBP2-50057]

Western Blot: c-Fos Antibody [NBP2-50057] - Analysis of cell lysates using rabbit pAb to c-FOS, NBP2-50057, dilution 1:5,000, in green, and mouse mAb to GAPDH, dilution 1:5,000, in red, used as a loading control. [1] protein standard (red), [2] HeLa cells grown in FBS free media, [3] HeLa cells stimulated with 20% FBS for 2 hours after being in FBS free media for 36 hours, [4] rat cortical neurons, [5] rat cortical neurons treated with membrane depolarization buffer for 5 hours. Multiple bands at 50-65 kDa in stimulated or treated cell lysates, correspond to different isoforms of the c-FOS protein
