Figure 1. MAP2 expression in cultured rat neurones visualised using HB9587.
HB9587 visualised the cell body, dendrites and axon of a cultured neurone. Method: neurones were cultured from PND2 rats following established protocols (Brewer and Torricelli, 2007. Nat Protoc 2, 1490–1498) and fixed with 4% PFA on DIV21. Cells were permeabilised with 0.1% Triton X-100 followed by blocking in 1% BSA, 300mM glycine. HB9587 was incubated overnight (4°C) at a 1:500 dilution (2µg/ml) followed by a one hour incubation with secondary antibody (Polyclonal goat anti-mouse DyLight 488 conjugated, Thermofisher 35503, 1:300 dilution). DAPI (HB0747) was used at 1µg/ml to visualise cell nuclei. For more detail please see our ICC protocol. Images were captured using a Leica SPE confocal laser scanning microscope coupled to a Leica DMi8 inverted epifluorescence microscope. The image was captured using a 63x objective (4.35x zoom), 405nm (45.6% power) and 488nm (31.2% power) laser lines in a z-stack (0.335 µm spacing). Deconvolution was carried out using Huygens Essential version (Scientific Volume Imagine) followed by the stack being flattened using a maximum Z projection in ImageJ (Schindelin et al., 2012. Nat Methods, 9(7), 676–682).

Figure 7. MAP2 expression in various tissue lysates and preparations.
HB9587 revealed a band of size greater than 250kDa only present in brain cytosol fractions. Method: mouse brain and rat brain membrane (P2) and cytosol fractions were prepared following previous work (Molnar et al., 1993. Neuroscience 53:307-326) from freshly collected adult brains. Other tissue lysates were prepared following established protocols from freshly dissected tissue. Samples were loaded (20µg / lane) onto a 5% acrylamide gel alongside a protein ladder (BioRad Precision Plus dual colour, 1610374) before being run at 60V for 41 minutes followed by 120V for 85 minutes. Wet transfer to a PVDF membrane was completed in 93 minutes using 400mA. The membrane was blocked for 2hrs in 5% non-fat dry milk before being incubated overnight at 4°C in HB9587 at a 1:1000 dilution (1µg/ml). Following washing the membrane was incubated in secondary antibody (1:10,000 dilution, Polyclonal goat anti-mouse HRP conjugated, Sigma Aldrich A3682) for 2hrs. For more detail please see our Western blotting protocol. Detection was accomplished using Clarity Western ECL substrate (BioRad, 1705061) and a Licor Odyssey Fc imaging system (ECL channel: 10 min exposure, 700nm channel: 30 sec exposure).
Figure 8. Concentration response of HB9587 staining in a rat brain cytosol preparation.
HB9587 shows consistent results with low background at dilutions as low as 1:4,000 (250 ng/ml). Method: cytosol fractions were prepared from fresh rat brains following established protocols (Molnar et al., 1993. Neuroscience 53:307-326).

Strips were blocked for 2hrs in 5% non-fat dry milk before being incubated overnight at 4°C in HB9587. Each strip was incubated separately with a separate HB9587 concentration with this ranging from 2µg/ml (1:500 dilution) to 31.3ng/ml (1:32,000 dilution). Following washing the membrane was incubated in secondary antibody (1:10,000 dilution, Polyclonal goat anti-mouse HRP conjugated, Sigma Aldrich A3682) for 2hrs. For more detail please see our Western blotting protocol. Detection was accomplished using Clarity Western ECL substrate (BioRad, 1705061) and a Licor Odyssey Fc imaging system (ECL channel: 10 min exposure, 700nm channel: 30 sec exposure).

| Amino acids | 1827 (199.5kDa) |
| Isoforms | MAP2 has 4 key isoforms: Isoform 1 (MAP2b), 1827aa, 199.5kDa; Isoform 2 (MAP2c), 471aa, 49.6kDa, missing aa152-1507 - juvenile isoform not expressed in adulthood; Isoform 3, 1823aa, 199.0kDa, missing aa152-155; Isoform 4, 559aa, 59.0kDa, multiple substitutions and missing aa230-1528. |
| Expression | Expressed highly within the brain (neuron specific) and to a lesser degree in the testes |
| Subcellular expression | Expressed as part of the cytoskeleton |
| Processing | None |
| Post translational modifications | MAP2 contains numerous phosphorylation sites however none occur with the epitope of HB9587 |
| Homology (compared to human) | Mouse and rat show 79.8% and 77.7% identity to human MAP2 respectively in a BLAST search. |
| Similar proteins | None |
| Epitope homology (between species) | Human, 100% identity Mouse, 76.2% identity Rat, 71.4% identity |
| Epitope homology (other proteins) | No significant homology with other proteins |
Storage & Handling
| Storage instructions | -20°C then use reconstitution advice |
| Reconstitution advice | We recommend reconstituting with either:
Take care when opening as the precipitate is extremely light and can easily be lost if disturbed. When reconstituting make sure that the antibody is thoroughly dissolved by pipetting up and down before giving the antibody a brief spin at <10,000g to make sure that all material is recovered and at the bottom of the tube. For more information please see our detailed guide on storing and using your antibody |
