Product Overview
This rabbit polyclonal antibody targets microtubule-associated protein 2 (gene MAP2) in human, mouse and rat samples and is validated for Western blot, IHC and ELISA. The predicted molecular weight is 199.5 kDa, and the supplier reports an observed band at about 280 kDa.
Microtubule-associated protein 2 (MAP2) is a neuron-specific protein concentrated in dendrites and cell bodies. It binds and stabilizes microtubules and helps shape dendrites, and MAP2 immunostaining is one of the most widely used methods to identify neurons and visualize dendritic arbors.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Mouse, Rat) |

Samples with a confirmed band (WB): human HeLa cells, human U-87MG cells.
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): mouse brain tissue, rat brain 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 MAP2 fragment (Ala360–Glu1101), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places microtubule-associated protein 2 in the cytoplasm and cell projection. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
