Trade Name

Description Anti-MAP2A Antibody, 2B
Alternate Names
  • Microtubule Associated Protein 2
Background Information MAP-2 (microtubule associated protein-2) is on of several high molecular weight proteins that play an important role in brain microtubule assembly. In addition to its association with microtubules, MAP-2 associates with neurofilaments and actin filaments suggesting that it may guide interaction among microtubules, other cytoskeletal elements, and cytoplasmic organelles (Binder, 1984).

MAP-2 is a stringent marker for neurons. In addition, MAP-2 displays intracellular specificity. In the central nervous system, MAP-2 is confined to neuronal cell bodies and dendrites. There are exceptions, however, where some axons stain positive for small amounts of MAP-2 (Caceres, 1984; Binder, 1986). MAP-2 is uniformly distributed throughout the cell when first expressed in cultured neurons but becomes selectively localized as dendritic development proceeds (Caceres, 1986; Dotti, 1987).

Product Information
Format Ascites
Control
  • Brain tissue
  • Cultured neurons
Presentation Unpurified mouse monoclonal IgG1 ascites fluid in buffer containing 15 mM sodium azide
Applications
Application Detect MAP2A using this Anti-MAP2A Antibody, 2B validated for use in IH & WB.
Key Applications
  • Immunohistochemistry
  • Western Blotting
Application Notes Immunohistochemistry:
1:50-1:200. AP20 stains dendrites and neuron cells bodies but not neuronal processes and axons. A previous lot of this antibody was used in immunohistochemistry.

Western blot:
SDS-PAGE Profiles: In SDS-PAGE MAP-2 from adult rat migrates as a closely associated doublet having a molecular weight of approximately 300 kD. However, early in brain development (postnatal day 10 in rats), MAP-2 migrates as a single band that is identical to the lower molecular weight band of the adult MAP-2 doublet (MAP-2b). Later in development (postnatal days 17-18), the mobility of MAP-2 changes to the adult doublet form. (In the spinal cord, conversion to the adult form occurs earlier).

Western blot: A 1:500 dilution was used in a previous lot.

Optimal working dilutions must be determined by end user.

Entrez Gene Number
Entrez Gene Summary This gene encodes a protein that belongs to the microtubule-associated protein family. The proteins of this family are thought to be involved in microtubule assembly, which is an essential step in neurogenesis. The products of similar genes in rat and mouse are neuron-specific cytoskeletal proteins that are enriched in dentrites, implicating a role in determining and stabilizing dentritic shape during neuron development. A number of alternatively spliced variants encoding distinct isforms have been described.
Gene Symbol
  • MAP2
  • MAP2B
  • MAP-2
  • MAP2C
  • DKFZp686I2148
  • MAP2A
Purification Method Unpurified
UniProt Number
UniProt Summary FUNCTION: SwissProt: P11137 # The exact function of MAP2 is unknown but MAPs may stabilize the microtubules against depolymerization. They also seem to have a stiffening effect on microtubules.
SIZE: 1827 amino acids; 199539 Da
PTM: MAP2A/c is phosphorylated. Phosphorylated upon DNA damage, probably by ATM or ATR.
SIMILARITY: SwissProt: P11137 ## Contains 3 Tau/MAP repeats.
Molecular Weight ~ 300 kDa

Storage and Shipping Information
Storage Conditions Stable for 1 year at -20ºC in undiluted aliquots from date of receipt.
Handling Recommendations: Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variability in freezer temperatures below -20°C may cause glycerol containing solutions to become frozen during storage.
