1_W19011B_PURE_FosB_Antibody_4_030222
IHC staining of purified anti-FosB (clone W19011B) on formalin-fixed paraffin-embedded human thymus tissue. Following antigen retrieval using 1x Tris-Buffered Saline (final concentration 0.05M) w/ Tween 20 (Cat. No. 925501), the tissue was incubated with 5 μg/mL of the primary antibody overnight at 4°C, followed by incubation with 2.5 μg/mL of Alexa Fluor® 647 goat anti-rat IgG (Cat. No. 405416) (red) for one hour at room temperature. Nuclei were counterstained with DAPI (blue), and the slide was mounted with ProLong™ Gold Antifade Mountant. The image was captured with a 20x objective. Scale bar: 50 μm

Description

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.

Immunogen
Full-length recombinant FosB protein
Formulation
Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide
Preparation
The antibody was purified by affinity chromatography.
Concentration
0.5 mg/mL
Storage & Handling
The antibody solution should be stored undiluted between 2°C and 8°C.
Application

IHC-P - Quality tested
ICC, ICFC - Verified
Recommended Usage

Each lot of this antibody is quality control tested by formalin-fixed paraffin-embedded immunohistochemical staining. For immunohistochemistry, a concentration range of 5 - 10 µg/mL is suggested. For immunocytochemistry, a concentration range of 5 - 10 μg/mL is recommended. For intracellular flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per million cells in 100 µL volume. It is recommended that the reagent be titrated for optimal performance for each application.

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.
