Target
- FunctionThis protein is associated with nerve growth. It is a major component of the motile "growth cones" that form the tips of elongating axons.
- Sequence similaritiesBelongs to the neuromodulin family.
Contains 1 IQ domain. - Post-translational
modificationsPhosphorylation of this protein by a protein kinase C is specifically correlated with certain forms of synaptic plasticity. - Cellular localizationCell membrane. Cell projection > growth cone membrane. Cell junction > synapse. Cytoplasmic surface of growth cone and synaptic plasma membranes.

Immunocytochemistry/ Immunofluorescence - Anti-GAP43 antibody - Neuronal Marker (ab16053)This image is courtesy of an anonymous abreview.ab16053 staining GAP43 in murine dorsal root ganglia by Immunocytochemistry/ Immunofluorescence.
Cells were fixed with methanol, permeabilized using 0.1% saponin/PBS, blocked with 4% BSA for 30 minutes at 25°C and then incubated with ab16053 at a 1/500 dilution for 14 hours at 4°C. The secondary antibody used was a DyLight 488 conjugated goat anti-rabbit polyclonal used at a 1/100 dilution. -

Secondary
Dako Goat polyclonal to Rabbit IgG (HRP) at 1/2000 dilution
Performed under reducing conditions.
Predicted band size : 43-53 kDa
Observed band size : 43 kDa (why is the actual band size different from the predicted?)
Additional bands at : 90 kDa (possible multimer). -
Immunohistochemistry (PFA fixed) - Anti-GAP43 antibody - Neuronal Marker (ab16053)This image is courtesy of Sophie Pezet, Univ London Kings Coll, United KingdomImmunofluorescent staining obtained with ab16053 Rabbit polyclonal to GAP43 in rat dorsal root ganglion, 2 weeks after a spinal nerve injury. The staining is localised in the cytoplasm of some lesioned neurons (arrow in B) and in many axons (arrow heads in B). Image B (X40 objective) is a higher magnification of A (X20). The staining disappeared completely when the antibody was pre-incubated with the immunising (blocking) peptide (ab16379).
Protocol details: Rats were intracardially perfused with 4% paraformaldehyde, DRG tissue was post-fixed overnight in the same fixative, cryoprotected in 20% sucrose and frozen in OCT. IHC free floating was performed on the fixed, frozen and cut (20µm sections) rat tissue. Primary antibody ab16053 was incubated overnight at toom temperature at 1/300. Secondary antibody Alexa fluor 488 was incubated at 1/1000 for 2 hours at room temperature.
