Scientific Data Images for MAP2 Antibody
Immunocytochemistry/Immunofluorescence Staining of MAP2 in Mouse Primary Cultures
Mouse primary cultures stained with MAP2 antibody. ICC/IF image submitted by a verified customer review.Immunocytochemistry/Immunofluorescence Staining of MAP2 in Rat Cortical Neuron-Glial Cells
Immunofluorescent analysis of cortical neuron-glial cell culture from E20 rat stained with chicken pAb to microtubule associated protein 2 (MAP2), NB300-213, dilution 1:10,000 in red, and mouse mAb to MAP-tau, NPB2-25162, dilution 1:2,000, in green. The blue is DAPI staining of nuclear DNA. NB300-213 antibody stains dendrites and perikarya of neurons, while NBP2-25162 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.Western Blot Detection of MAP2 in Rat Brain Tissue Lysates
Western blot analysis of whole brain tissue lysates using chicken pAb to microtubule associated protein 2 (MAP2), NB300-213, dilution 1:50,000 in green: [1] protein standard (red), [2] adult rat brain, [3] embryonic E20 rat brain, [4] adult mouse brain. Strong band observed at ~280 kDa mark 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 higher concentrations.Applications for MAP2 Antibody

Background: MAP2
MAP2 isoforms are developmentally regulated and differentially expressed in neurons and some glia. MAP2c is predominantly expressed in the developing brain while the other isoforms are expressed in the adult brain. The distribution of MAP2 isoforms also varies, with MAP2a and MAP2b predominantly localized to dendrites, while MAP2c is also found in axons. Lastly, the expression of MAP2d is not limited to neurons and may be found in glia, specifically oligodendrocytes (1, 2). MAP2 isoforms associate with microtubules and mediate their interaction with actin filaments thereby playing a critical role in organizing the microtubule-actin network. In neurons, MAP2 isoforms are implicated in different processes including neurite initiation, elongation and stabilization as well as axon and dendrite formation (2). Knockout of MAP expression in animal models results in a variety of functional and structural brain defects according to the isoform affected (e.g., reduced LTP and LTD, reduced myelination, absence of corpus collosum, motor system malfunction, abnormal hippocampal dendritic morphology, abnormal synaptic plasticity) (4).
