General description

MAP-2 (microtubule associated protein-2) is one of several high molecular weight proteins that play an important role in brain neuron microtubule assembly. In addition to its association with microtubules, MAP-2 associates with neurofilaments and actin filaments suggesting that it may guide interaction among microtubules, other cytoskeletal elements, and cytoplasmic organelles. MAP-2 is a stringent marker for neurons. In addition, MAP-2 displays intracellular specificity. In the central nervous system, MAP-2 is confined to neuronal cell bodies and dendrites. There are exceptions, however, where some axons stain positive for small amounts of MAP-2. MAP-2 is uniformly distributed throughout the cell when first expressed in cultured neurons but becomes selectively localized as dendritic development proceeds. (Caceres, 1986; Dotti, 1987).

Specificity

MAB3418 binds specifically to MAP-2.
Expected to cross-react with human, cow, chicken, quail, and Xenopus.

Immunogen

Bovine brain microtubule protein.

Application

Research Sub Category
Neuronal & Glial Markers
Anti-MAP2 Antibody, clone AP20 detects level of MAP2 & has been published & validated for use in IH & WB.
Western Blot:
60 ng/mL. In SDS-PAGE, MAP-2 from adult rat migrates as a closely associated doublet having a molecular weight of approximately 280-300 kD representing the MAP-2A and -2B isoforms but not the 70 kDa MAP-2C isoform. However, early in brain development (postnatal day 10 in rats), MAP-2 migrates as a single band that is identical to the lower molecular weight band of the adult MAP-2 doublet (MAP-2b). Later in development (postnatal days 17-18), the mobility of MAP-2 changes to the adult doublet form. (In the spinal cord, conversion to the adult form occurs earlier). Users should run 4%-20% SDS-PAGE gradient gels.

Immunohistochemistry:
5 µg/mL (4% PFA fixed frozen sections).

Immunohistochemistry:
5 µg/mL of a previous lot was used. Anti-MAP-2 can be used to stain tissue (brain or spinal cord) fixed with paraformaldehyde.

Optimal working concentrations must be determined by the end user.

Protein A purified
Purified mouse monoclonal IgG1 in buffer containing 0.02 M Phosphate buffer, pH 7.6, 0.25 M NaCl with 0.1% sodium azide.

Storage and Stability

Stable for 6 months at 2-8°C in undiluted aliquots from date of receipt.
During shipment, small volumes of product will occasionally become entrapped in the seal of the product vial. For products with volumes of 200 µL or less, we recommend gently tapping the vial on a hard surface or briefly centrifuging the vial in a tabletop centrifuge to dislodge any liquid in the container’s cap.
