  • Scientific Background Microtubules are 25nm diameter protein rods found in most kinds of eukarytic cells. They are polymerized from a dimeric subunit made of one a subunit and one b tubulin subunit. Microtubules are associated with a family of proteins called microtubule associated proteins (MAPs), which includes the protein t (tau) and a group of proteins referred to as MAP1, MAP2, MAP3, MAP4 and MAP5. MAP2 is made up of two ~280 kDa apparent molecular weight bands referred to as MAP2a and MAP2b. A third lower molecular weight form, usually called MAP2c, corresponds to a pair of protein bands running at ~70 kDa on SDS-PAGE gels. All these MAP2 forms are derived from a single gene by alternate transcription, and all share a C-terminal sequence which includes either three or four microtubule binding peptide sequences, which are very similar to those found in the related microtubule binding protein t (tau). MAP2 isoforms are expressed only in neuronal cells and specifically in the perikarya and dendrites of these cells. Antibodies to MAP2 are therefore excellent markers on neuronal cells, their perikarya and neuronal dendrites.

    Images, Protocols & SDS

  • View of mixed neuron/glial cultures stained with Chicken polyclonal antibody to Microtubule Associated Protein 2 C-1382-50 (red). The perikarya and dendrites of neurons are strongly and specifically stained with this antibody while the axons of the neurons and the processes of all other cell types in these cultures (astrocytes, oligodendrocytes, microglia, endothelia and fibroblasts) are all negative. Cell nuclei are visualized with DAPI DNA stain.

  • View of a thin section of adult rat cerebellum stained with Chicken polyclonal antibody to Microtubule Associated Protein 2 C-1382-50 (green), Rabbit polyclonal to GFAP R-1374-50 (red) and DNA (blue). The image shows the molecular layer (outside of lobe) and granular layer; blue since its full of small neurons and the white matter in the middle.


    Left: Analysis of MAP2 expression in cortical neuron-glial cell culture from E20 rat by Immunocytochemistry with chicken anti-MAP2 (1:10,000, red), co-stained with a mouse antibody to MAP-tau (green). Blue: DAPI nuclear stain. The MAP2 antibody stains dendrites and perikarya of neurons, while the MAP-tau antibody labels neuronal perikarya, dendrites and also axonal process. As a result perikarya and dendrites appears orange-yellow, since they contain both MAP2 and tau, while axons are green. Right: Western blot analysis of whole brain tissue lysates using chicken antibody to MAP2 (1:50,000). [1] protein standard, [2] adult rat brain, [3] embryonic E20 rat brain, [4] adult mouse brain. A strong band at around 280 kDa corresponds to two major isoforms of MAP2 protein referred to as MAP2A and MAP2B. Smaller fragments of these isoforms are also detected if the antibody is used at lower dilutions.
