Our Anti-Growth Associated Protein 43 (GAP-43) rabbit polyclonal primary antibody detects bovine, human, mouse, and rat Growth Associated Protein 43 (GAP-43), and is affinity-purified. It is validated for use in ICC, WB.

A: Western blot analysis of GAP43 expression in cow cerebellum. R-1651-100 detects a single band at ~43 kDa, which corresponds to full-length GAP43 protein.B: Immunofluorescence analysis of mixed neuron-glia cultures with GAP43 rabbit antibody R-1651-100 (red). DNA is stained blue.

Left: Analysis of cortical neuron-glial cell culture from E20 with rabbit antibody to GAP43 (green, 1:2,000) by Immunocytochemistry. Cells were co-stained with a mouse antibody to vimentin (red). Blue: DAPI nuclear stain. The GAP43 antibody labels protein expressed in the axonal membrane of neuronal cells, while the vimentin antibody stains intermediate filaments in fibroblasts and other non-neuronal cells. Right: Western blot analysis of tissue and cell lysates using rabbit antibody to GAP43 (green, 1:20,000). [1] protein standard, [2] rat brain, [3] rat spinal cord, [4] mouse brain, [5] mouse spinal cord, [6] SH-SY5Y cells, [7] C6. The single band at 43 kDa corresponds to GAP43 protein. The GAP43 protein is detected only in the lysates of neuronal origin. Rat glioblastoma C6 cells do not express GAP43 protein (lane 7).

Growth Associated Protein 43 (GAP-43)

Scientific Background

GAP43 is very abundant protein which is found concentrated in neurons. One group discovered it as one of three proteins which becomes unregulated during the regeneration of the toad optic nerve (1). Three GAPs (Growth associated proteins) were discovered, and the number 43 comes from the apparent SDS-PAGE molecular weight of the one named GAP43. The HGNC name for this protein is, not surprisingly, GAP43. Later work showed that GAP43 does not run on SDS-PAGE in a fashion which accurately reflects its molecular weight, and that GAP43 proteins from different species may run at different apparent molecular weights. Partly due to these features GAP43 were independently discovered by several different groups and therefore has several alternate names, such as protein F1, pp46, neuromodulin, neural phosphoprotein B-50 and calmodulin-binding protein P-57. In each case the number reflects the apparent SDS-PAGE molecular weight, and underlines the unusual properties of this molecule. Mammalian GAP43 proteins contains only 226-243 amino acids, and so the real molecular weight is 23.61-25.14 kDa. GAP43 has been extensively studied and is known to be a major protein kinase C substrate and to bind calmodulin avidly. GAP43 is anchored to the plasma membrane by palmitoylation modifications.

Storage

Spin vial briefly before opening. Reconstitute with 100 µL sterile-filtered, ultrapure water. Centrifuge to remove any insoluble material. Store lyophilized, unopened vial at 2-8°C or lower. After reconstitution, prepare aliquots and store at -20°C to -80°C for a higher stability. Avoid freeze-thaw cycles.

Physical State

Lyophilized

Buffer

Lyophilized from PBS buffer pH 7.2-7.6 with 0.1% trehalose, and sodium azide

Dilution Ranges

WB: 1:5000-1:20000
ICC: 1:500-1:2000

Conjugate

Unconjugated

Specificity

The antibody reacts with a 43 kDa band by Western blot on bovine cerebellum homogenate. The molecular weight of the protein recognized can vary (~43-57 kDa) depending on the species and the percentage acrylamide used in the SDS-PAGE gel. It has also been used successfully for immunocytochemistry.
