General description

The microtubule-associated protein 2 (MAP2) is an abundant neuronal cytoskeletal protein that binds to tubulin and stabilizes microtubules. (Herzog and Weber, 1978). MAP2 is essential for the development and maitenance of neuronal morphology (Matus, 1991). In neurons MAP2 occurs as three primary isoforms, the high molecular weight MAP2a, MAP2b, and the low molecular weight MAP2c, that result from alternative splicing of the MAP2 gene (Chung et al., 1996). The low molecular weight isoform, MAP2c, is expressed in developing brain and is down-regulated during brain maturation, whereas the high molecular weight MAP2b is expressed in both developing and adult brain. The MAP2a appears only after brain maturation (Tucker, 1990). All these forms bind to microtubules through a domain near the carboxyl terminus that contains either three or four similar repeats of a 31-amino-acid motif (Lewis et al., 1988). MAP2 together with MAP4 and tau proteins belong to the family of thermostable proteins associated with microtubules.

Specificity

Reactivity with other species has not been determined.
Specific for Microtubule-associated protein 2 (MAP2). The antibody recognizes all MAP2 isoforms (MAP2A, MAP2B, MAP2C and MAP2D). It shows greatest immunoreactivity with the HMW-MAP2 (MAP2A and MAP2B).

Immunogen

Purified Microtubule-associated protein from rat brain.

Application

Detect Microtubule-Associated Protein 2 (MAP2) using this Anti-Microtubule-Associated Protein 2 (MAP2) Antibody validated for use in ELISA, IC, IH, IH(P) & WB with more than 55 product citations.

Immunocytochemistry:
1:1,000 dilution of a previous lot was used on primary neurons.

Immunohistochemistry:
1:1,000 dilution on 4% paraformaldehyde / PBS fixed tissue sections.

Immunoblot:
1:2,000 dilution was used on a previous lot. Recognizes MAP2A (280-300kDa, and MAP2B (270-280KDa), and to a lesser extent MAP2C (70kDa) and MAP2D (70-75kDa).

ELISA:
greater than or equal to1:2,000 dilution of a previous lot was used.

Optimal working dilutions must be determined by the end user.

Quality

Immunohistochemistry(paraffin) Analysis:
MAP2 (cat. # AB5622) staining on Normal Cerebellum. Tissue pretreated with Citrate, pH 6.0. This lot of antibody was diluted to 1:500, using IHC-Select Detection with HRP-DAB. Immunoreactivity is seen as fiber-like- staining (brown) on microtubule.
