BD Pharmingen™ Purified Mouse Anti-MAP2
Clone Ap20 (RUO)
Western blot analysis of MAP2. Rat brain lysate was probed with anti- MAP2 at concentrations of 4.0 (lane 1), 2.0 (lane 2), and 1.0 µg/ml (lane 3). MAP2 is identified as a band of ~280 kDa.

Preparation And Storage
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. Store undiluted at 4°C.
Recommended Assay Procedures
Applications include western blot analysis (1-2 µg/ml), immunoprecipitation, and immunohistochemistry of paraformaldehyde-fixed tissue cultured cells, and frozen tissue sections. T98G human glioblastoma cells (ATCC CRL-1690) and rat brain enriched microtubule protein preparations are suggested as positive controls.
Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.

Antibody Details
Ap20
Microtubule-associated protein 2 (MAP2) is a neuronal cytoskeletal protein that binds to tubulin and stabilizes microtubules. It is expressed in the cell body and dendrites of neurons, but is absent in neuronal processes. The expression of MAP2 is developmentally regulated, and there are multiple high and low molecular weight isoforms, all derived from one MAP2 gene. MAP2a, MAP2b, and MAP2c are the three major MAP2 isoforms. The high molecular weight MAP2 isoforms, MAP2a and MAP2b consist of a large projection arm and a short microtubule binding domain. The low molecular weight MAP-2 isoform, MAP2c, lacks most of the projection arm of the high molecular weight isoforms. MAP2c is the earliest expressed MAP2 and is derived by alternative splicing MAP2a and MAP2b are considered to be adult expressed MAPs, with MAP2a expression occuring later in development than MAP2b expression. MAP2a is thought to result from a post-translational modification of MAP2b. High molecular weight MAP2 isoforms (2a and 2b) migrate as a doublet at a molecular weight of >300 kDa. The low molecular weight MAP2 isoform 2c migrates at 70 kDa.
The Ap-20 antibody recognizes high molecular weight MAP2 isoforms MAP2a and MAP2b. Specifically, it has been shown to recognize MAP2a and MAP2b from human, bovine, rat, frog, and quail cells and tissues. Ap-20 does not recognize the low molecular weight MAP2 isoforms (MAP2c) or other microtubule proteins. Ap-20 reacts with an epitope between amino acids 997-1332 of high molecular weight MAP2 isoforms.4 Bovine MAP2 was used as immunogen.

Format Details
Purified
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
