W20103F_PURE_JunB_Antibody_1_021122
ICC staining of purified anti-JunB (clone W20103F) on NTERA-2 (negative control, panel A) and HeLa (positive control, panel B) cells. The cells were fixed with 4% PFA and permeabilized with Triton X-100, and blocked with 5% FBS for 1 hour at room temperature. The cells were then stained with 5.0 µg/mL of the primary antibody, followed by incubation with 2.5 µg/mL of Alexa Fluor® 594 goat anti-rat IgG (Cat. No. 405422) for 1 hour at room temperature. Nuclei were counterstained with DAPI, and the image was captured with a 60X objective. Predicted protein expression was obtained from Human Protein Atlas and confirmed with an independent antibody against JunB.

Description

JunB is a member of the AP-1 family of transcription factors, which also includes c-Jun, c-Fos, Fra1, and JunD. JunB can form dimers with other Jun and Fos proteins, as well as members of the ATF transcription factor family, to form a functional AP-1 transcription factor complex. AP-1 complexes containing JunB can exert both activator and repressor function depending on the interacting partner and promoter sequence context. JunB displays both tumor suppressor and oncogenic activity, inducing genes involved in cell senescence and repressing genes involved in proliferation. JunB is required for T helper type 2 (Th2), T helper 17 (Th17) cell and regulatory T cell (Treg) differentiation. Multiple cancers display aberrant JunB expression and function. In some lymphomas, notably Hodgkin’s lymphoma, JunB expression is elevated and the protein functions as an oncogenic transcription factor. Conversely, loss of JunB is observed in chronic myeloid leukemia.

Partial recombinant human JunB 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

Application

ICC - Quality tested
ICFC - Verified
Recommended Usage

Each lot of this antibody is quality control tested by immunocytochemistry. For immunocytochemistry, a concentration range of 5.0 μg/mL is recommended. For flow cytometric staining, the suggested use of this reagent is ≤ 0.06 µg per million cells in 100 µL volume. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

When using this clone for ICC, we recommend 4% PFA + Triton X-100 for fixation and permeabilization. Other methods tested (4% plus methanol and methanol only) fixation and permeabilization methods produced high non-specific staining.

This clone failed to detect JunB by WB and IHC-P.
