General description

MAP2 is the major microtubule associated protein of brain tissue. There are three forms of MAP2; two are similarly sized with apparent molecular weights of 280 kDa (MAP2a and b) and the third with a lower molecular weight of 70 kDa (MAP2c). In the newborn rat brain, MAP2b and MAP2c are present while MAP2a is absent. Between postnatal days 10 and 20, MAP2a appears at levels equal to that of MAP2b. At the same time, the level of MAP2c drops by 10-fold. This change happens during the period when dendrite growth is completed and neurons have reached their mature morphology.
MAP2 is known to promote microtubule assembly and to form side arms on microtubules. It also interacts with neurofilaments, actin and other elements of the cytoskeleton.

Specificity

Reacts with all known forms of MAP2, namely MAP2a, MAP2b and MAP2c. Does not cross-react with other MAPs or tubulin. By immunohistochemical staining of formalin-fixed, paraffin-embedded brain tissue, the antibody shows selective labeling of dendritic trees throughout the brain.

Immunogen

rat brain microtubule-associated proteins (MAPs).

Application

Anti-MAP2 antibody has been used in immunofluorescence. It has also been used in immunohistochemistry.
May be used in various immunochemical techniques including immunoblotting, immunohistochemistry, and immunocytochemistry. Monoclonals antibodies to MAP2 are used to study the cytoskeleton structure in cells.
By immunoblotting, a working antibody concentration of 1-2 μg/ml is recommended using a rat brain extract.

Biochem/physiol Actions

MAP2 (microtubule-associated protein 2) expression is monitored to predict the disease progression in glioma. MAP2 is critical in the formation of dendritic protrusions in astrocytes and oligodendrocytes. In eukaryotes, MAP2 is essential for spindle assembly and chromosome segregation.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, and 15 mM sodium azide.

Storage and Stability

For continuous use, store at 2-8 C for up to one month. For extended storage, freeze in working aliquots at 20 C. Repeated freezing and thawing, or storage in frost-free freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.
