Anti-Growth-Associated Protein-43 (GAP-43) Antibody

This antipeptide IgY antibody was generated in chickens against a C-terminal sequence shared between the mouse (NP_032109) and rat (NP_05889.1) gene products. It has been validated with human, mouse and rat tissues.

Background

Growth-Associated Protein-43 is a 274 amino acid cytoplasmic protein found in neurons and various other embryonic cell types. This protein also goes by a number of alternative names, including neuromodulin and F1. In cultured neurons, GAP-43 antibodies selectively stain the growth cones of axons. As the substrate for various phosphorylation events, it is believed that GAP-43 plays a critical role in axonal growth, although its exact function is still unclear.

Synonyms

Neuromodulin, Axonal membrane protein GAP-43, Growth-associated protein 43, Neural phosphoprotein B-50, pp46)

Assay Protocol

Chickens were immunized with a synthetic peptide corresponding to the C-terminal region of mouse GAP-43 coupled to keyhole limpet hemocyanin. After repeated injections, immune eggs were collected, the IgY fractions were purified from the yolks, and the IgY concentration adjusted to 20 mg/mL. This preparation was then diluted 1:10 with PBS containing bovine serum albumin as a carrier. Finally, the antibody preparation was filter-sterilized.

Quality Control

Quality assurance analysis was performed using immunohistochemistry (at a dilution of 1:1000) using fluorescein-labeled goat anti-chicken IgY (1:1000 dilution, Aves Labs Cat.# F-1005) as the secondary reagent.
