Invitrogen™ MAP2 Monoclonal Antibody (M13) 

Description

This antibody reacts with a 300 kD cytoskeletal protein (MAP2A and MAP2B) primarily expressed in the somatodendritic domain of the neuron but is also found in the glia. Reactivity is not affected by phospohorylation state of MAP2. Abnormal expression of MAP2 may cause cytoskeletal abnormalities and impair signal transduction in dendrites. This antibody is suitable for immunohistochemical staining of alcohol-fixed paraffin embedded or frozen tissue sections.

MAP2 (Microtubule Associated Protein 2) exists in two high molecular weight forms (MAP2a & MAP2b) and a low molecular weight form. The expression of MAP2 is developmentally regulated and its multiple forms arise by alternative splicing of a single gene. MAP2 is involved in microtubule assembly, which is an essential step in neurogenesis. The products of similar genes in rat and mouse are neuron-specific cytoskeletal proteins that are enriched in dendrites, implicating a role in determining and stabilizing dendritic shape during neuron development. MAP2 is useful in studies of neuron structure in normal and malignant brain tissue as well as in degenerative diseases such as Alzheimer's Disease (AD).
