Biolegend, 600857, PE anti-FosB Antibody, 25tests

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.

Verified Reactivity: Human
Antibody Type: Monoclonal
Host Species: Rat
Immunogen: Full-length recombinant FosB protein
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and BSA (origin USA)
Preparation: The antibody was purified by affinity chromatography and conjugated with PE under optimal conditions.
Concentration: Lot-specific (to obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.)
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light. Do not freeze.
Application: ICFC - Quality tested
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. ICFC: Cells were fixed and permeabilized using True Phos Buffer system.
RRID: AB_2941601 (BioLegend Cat. No. 600857) AB_2941601 (BioLegend Cat. No. 600858)
Structure: FosB is a 338 amino acid protein with a predicted molecular weight of 36kD.
Distribution: FosB is widely expressed in developing and adult tissues, including the brain, thyroid, bladder and adipose tissue.
Function: FosB heterodimerizes with proteins of the Jun family to form the transcription factor AP-1 to regulate cell proliferation, survival, and differentiation.
