Product Overview
This rabbit polyclonal antibody recognizes myocyte-specific enhancer factor 2B (gene MEF2B) in human, mouse and rat samples and is validated for Western blot, IHC and ELISA. The predicted molecular weight is 38.6 kDa, and the supplier reports an observed band at about 50 kDa.
MEF2B is a MADS-box transcription factor of the MEF2 family. Unlike its relatives, it is notably expressed in germinal-center B cells, where it regulates genes such as BCL6. Recurrent MEF2B mutations occur in diffuse large B-cell lymphoma and follicular lymphoma, so it is studied in B-cell biology and lymphoma.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human, Mouse, Rat) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): rat skeletal muscle tissue, rat brain tissue, mouse skeletal muscle tissue, mouse brain tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human hodgkin lymphoma tissue, human tonsil tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Recombinant human MEF2B fragment (Arg127–Asp352), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places myocyte-specific enhancer factor 2B in the nucleus. Tissue expression noted by UniProt (human): Expressed in skeletal and cardiac muscle and brain. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
