|Detection of Rat Draxin by Western Blot. Western blot shows lysates of rat embryonic hippocampal glial cells. PVDF Membrane was probed with 1 µg/mL of Mouse/Rat Draxin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6149) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Draxin at approximately 58 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.|
|Draxin in Mouse Embryo. Draxin was detected in immersion fixed frozen sections of mouse embryo (E13) using Mouse Draxin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6149) at 5 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to neuronal cells in the midbrain. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.|
Draxin (Dorsal repulsive axon guidance protein; also neucrin) is a secreted, 58 kDa, presumable glycoprotein member of the Draxin family of molecules. In mammals, it is expressed in neurons (axons), astroglia, and likely cells of the developing somite. Draxin acts as a Wnt antagonist, apparently by binding to LRP6. The net effect is to block neural crest migration, and the organization of axons into functional tracts or bundles (fasciculation). Mature mouse Draxin is 318 amino acids (aa) in length. It contains one potential N-linked glycosylation site, followed by a Cys-rich domain (aa 268-327). Mature mouse Draxin (aa 26-343) shares 80% aa identity with mature human Draxin, and 94% aa identity with mature rat Draxin.
