FRA-1/FOSL1 Antibody (JE33-20)

Western Blot: FRA-1/FOSL1 Antibody (JE33-20) [NBP3-32350] - Western blot analysis of FRA-1/FOSL1 on different lysates with Rabbit anti-FRA-1/FOSL1 antibody (NBP3-32350) at 1/1,000 dilution. Lane 1: MDA-MB-231 cell lysate Lane 2: U-87 MG cell lysate Lane 3: A431 cell lysate Lane 4: HeLa cell lysate (negative) Lane 5: HEK-293 cell lysate (negative) Lysates/proteins at 20 ug/Lane. Predicted band size: 29 kDa Observed band size: 37 kDa (40 kDa unknown) Exposure time: 35 seconds; 4-20% SDS-PAGE gel. Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (NBP3-32350) at 1/1,000 dilution was used in 5% NFDM/TBST at room temperature for 2 hours. Goat Anti-Rabbit IgG - HRP Secondary Antibody at 1:100,000 dilution was used for 1 hour at room temperature.

Immunohistochemistry: FRA-1/FOSL1 Antibody (JE33-20) [NBP3-32350] - Immunohistochemical analysis of paraffin-embedded human cervical carcinoma tissue with Rabbit anti-FRA-1/FOSL1 antibody (NBP3-32350) at 1/3,000 dilution. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 2 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (NBP3-32350) at 1/3,000 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Immunocytochemistry/ Immunofluorescence: FRA-1/FOSL1 Antibody (JE33-20) [NBP3-32350] - Immunocytochemistry analysis of U-87 MG cells labeling FRA-1/FOSL1 with Rabbit anti-FRA-1/FOSL1 antibody (NBP3-32350) at 1/100 dilution. Cells were fixed in 100% methanol for 10 minutes, permeabilized with 0.1% Triton X-100 in PBS for 15 minutes, and then blocked with 1% BSA for 30 minutes at room temperature. Cells were then incubated with Rabbit anti-FRA-1/FOSL1 antibody (NBP3-32350) at 1/100 dilution in 2% negative goat serum overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (iFluor™ 488) was used as the secondary antibody at 1/1,000 dilution. Nuclear DNA was labelled in blue with DAPI. Beta tubulin (red) was stained at 1/100 dilution overnight at +4℃. Goat Anti-Mouse IgG H&L (iFluor™ 594) was used as the secondary antibody at 1/1,000 dilution.

Flow Cytometry: FRA-1/FOSL1 Antibody (JE33-20) [NBP3-32350] - Flow cytometric analysis of U-87 MG cells labeling FRA-1/FOSL1. Cells were fixed and permeabilized. Then stained with the primary antibody (NBP3-32350, 1ug/ml) (red) compared with Rabbit IgG Isotype Control (green). After incubation of the primary antibody at +4℃ for an hour, the cells were stained with a iFluor™ 488 conjugate-Goat anti-Rabbit IgG Secondary antibody at 1/1,000 dilution for 30 minutes at +4℃. Unlabelled sample was used as a control (cells without incubation with primary antibody; black).

Background

The Fos gene family consists of 4 members: FOS, FOSB, FOSL1, and FOSL2. These genes encode leucine zipper proteins that can dimerize with proteins of the JUN family, thereby forming the transcription factor complex AP-1. As such, the FOS proteins have been implicated as regulators of cell proliferation, differentiation, and transformation.
