General description

GAP-43, a common marker of differentiating neurons, is expressed at elevated levels by developing or regenerating neurons during axon growth. While GAP-43 is an integral membrane protein associated with the cytoplasmic surface of axonal growth cones (and synapses), it is absent from dendritic growth cones. In adult brain, GAP-43 is found in high concentration in presynaptic areas where memory formation is thought to occur, such as frontal cortex, limbic system and hippocampus. Phosphorylation of GAP-43 by PKC (at Ser41 on human, mouse, rat, and bovine GAP-43 or Ser42 on chicken and Xenopus GAP-43) is specifically correlated with certain forms of synaptic plasticity.


AB5312 specifically recognizes GAP-43 regardless of the protein′s phosphorylation state. This antiserum has been refered to in the literature as CG-1.


Purified GAP-43 from feline brain (McIntosh and Parkinson, 1990).


Immunocytochemistry: 1:100-1:400 for mouse primary neurons, NTera2 neurons.

Immuohistochemistry: 1:2,000 on coronal sections of adult visual cortex (McIntosh and Parkinson, 1990). AB5312 has been used to stain GAP-43 in 4% paraformaldehyde-fixed paraffin-embedded tissue sections of mouse olfactory bulb (Legrier, 2001).

Western blot: 1:500 - 1:1,000. Detects a single band at approximately 50 kDa on western blots of protein extracts from adult visual cortex (McIntosh and Parkinson, 1990).


Optimal working dilutions must be determined by end user.
