Western blot analysis of MAP2B on rat brain lysate. Lane 1: 1:2500, lane 2: 1:5000, lane 3: 1:10000 dilution of MAP2B.
Immunofluorescent staining of undifferentiated (left) and differentiated (right) SH-SY5Y cells. Cells were seeded in a collagen coated 384 well imaging plate (Material # 353962) at ~ 8,000 cells per well. After overnight incubation, cells were stained using the methanol fix/perm protocol (see Recommended Assay Procedure) and the anti-MAP2B antibody. Differentiated cells were seeded in a 96 well, collagen coated imaging plate (Material # 353219) at ~ 5,000 cells per well. Cells were incubated with 50 mM ATRA (Sigma, R2625) for 5 days, followed by 50 ng/ml BDNF (Sigma, B3795) for 5 days. Differentiated cells were fixed and stained using the methanol fix/perm protocol, and the anti-MAP2B antibody. The second step reagent in both cases was Alexa Fluor® 488 goat anti mouse Ig (Invitrogen). The images were taken on a Pathway 855 or 435 imager using a 20x objective. This antibody also stained undifferentiated SK-N-SH cells using both the Triton X100 and methanol fix/perm protocols (see Recommended Assay Procedure).

Recommended Assay Procedures
Methanol Procedure for a 96 well plate:
Remove media from wells. Add 100 µl/well fresh 3.7% Formaldehyde in PBS. Incubate for 10 minutes at room temperature (RT). Flick out and add 100 µl/well 90% methanol. Incubate for 5 minutes at RT. Flick out and wash twice with PBS. Flick out PBS and add 100 µl/well blocking buffer (3% FBS in PBS). Incubate for 30 minutes at RT. Flick out and add diluted antibody (diluted in blocking buffer). Incubate for 1 hour at RT. Wash three times with PBS. Flick out PBS and add second step reagent. Incubate for 1 hour at RT. Wash three times with PBS. Image sample.
Triton-X 100 Procedure for a 96 well plate:
Remove media from wells. Add 100 µl/well fresh 3.7% Formaldehyde in PBS. Incubate for 10 minutes at room temperature (RT). Flick out and add 100 µl/well 0.1% Triton-X 100. Incubate for 5 minutes at RT. Flick out and wash twice with PBS. Flick out PBS and add 100 µl/well blocking buffer (3% FBS in PBS). Incubate for 30 minutes at RT. Flick out and add diluted antibody (diluted in blocking buffer). Incubate for 1 hour at RT. Flick out and wash three times with PBS. Flick out and add second step reagent. Incubate for 1 hour at RT. Flick out and wash three times with PBS. Image sample.
Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.

- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

Microtubule-associated proteins (MAPs) play a crucial role in the development and morphology of neurons. MAP2, specifically localized in dendrites, has four known isoforms that are produced by alternative splicing of the transcript and are expressed at various stages of neuronal development. MAP2B is a 280-kDa protein that is expressed throughout brain development. It contains functional domains that interact with the regulatory subunit of the cAMP-dependent kinase II and microtubules. Experimental monitoring of its presence, along with GFAP and nestin, may be utilized to quantify neuronal development.
