HeLa cells untreated (negative control, open histogram) or treated with 100 ng/ml PMA for 4 hours (positive control, filled histogram) were fixed and permeabilized using the True Phos™ Fix/Perm Buffer Set (Cat. No. 425401), and intracellularly stained with PE anti-FosB (clone W19011B) or PE rat IgG2a, κ isotype control (open histogram, dashed line) (representative histogram for untreated and treated cells) (Cat. No. 400507).

FosB is a member of the FOS family of proteins that dimerizes with proteins of the Jun family to form the AP-1 transcription factor complex. As part of AP-1, FosB plays a critical role in regulating cell differentiation, proliferation, and apoptosis. FosB is expressed in most tissues and has been particularly well-studied in the CNS. ΔFosB, a truncated splice variant of the FOSB gene, plays a critical role in the brain’s reward circuit plasticity, with significant impact on both natural and pathological behavior. FosB also functions as a tumor suppressor, and dysregulation of FosB activity or levels has been found in numerous cancers, including gastric, prostate and colorectal cancer.

- Recommended Usage
-
Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µL per million cells in 100 µL staining volume or 5 µL per 100 µL of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.
- Excitation Laser

Blue Laser (488 nm)
Green Laser (532 nm)/Yellow-Green Laser (561 nm)
- Application Notes
-
For ICC, we recommend fixation in 4% PFA and permeabilization for 6 minutes in 0.5% Triton-X.
Methanol only and PFA + Methanol fix/perm methods were tested and produced inferior signal.
