Description_x000D_ General description_x000D_ Microtubule-associated protein 2 (MAP2) is a neuronal protein. It belongs to the MAP2/Tau family. This gene is located to human chromosome 2q34-q35. MAP2 is present in neurons. 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 280kDa (MAP2a and MAP2b) and the third with a lower molecular weight of 70kDa (MAP2c)._x000D_ Specificity_x000D_ 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._x000D_ Immunogen_x000D_ rat brain microtubule-associated proteins (MAPs)._x000D_ Application_x000D_ Monoclonal Anti-MAP2 (2a+2b) antibody has been used in immunohistochemistry, immunostaining and western blotting._x000D_ Physical form_x000D_ Supplied as ascites fluid with 15 mM sodium azide as a preservative._x000D_ Storage and Stability_x000D_ For continuous use, store at 2-8 °C for up to one month. For extended storage, the solution may be frozen in working aliquots. 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._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ Microtubule-associated protein 2 (MAP2) interacts with microtubules to maintain the structure of dendrites. It plays a major role in supporting the actin cytoskeleton in spines, binding and nucleating filamentous actin (f-actin) to modulate spine morphology.
