These B-50 ELISA kits are immunodetection tools for measuring the levels of B-50 in biological samples. B-50 is an alias of the human GAP43 gene, which encodes the protein, growth associated protein 43. Notably, B-50 is known to play a role in astrocyte differentiation, among other functions. The GAP43 protein is 238 amino acid residues in length and 24.8 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the cell membrane of the cell. This protein is known to be palmitoylated and phosphorylated. Other names for this target antigen include B-50.
