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.

- Application
-
ICFC (test sizes) - Quality tested
ICC (µg size) - Quality tested - Recommended Usage
-
Each lot of the test-sized antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining using the test sizes, 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.
Each lot of the µg-sized antibody is quality control tested by immunocytochemistry. For immunocytochemistry using the ug size, a concentration range of 1.25 - 5.0 μg/mL is recommended. It is recommended that the reagent be titrated for optimal performance for each application.
* Alexa Fluor® 647 has a maximum emission of 668 nm when it is excited at 633 nm / 635 nm.
