Anti-MAP2A Antibody, AP20

产品说明

一般描述

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).

特异性

MAP2a & b. Does not recognize other variants.

免疫原

Bovine MAP2

应用

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-AP20). 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.

储存及稳定性

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.
