Detection of Recombinant Human DSCAM by Western Blot. Western blot shows 25 ng of Recombinant Human DSCAM (Catalog # 3666-DS) and Recombinant Human DSCAM‑L1 (Catalog # 3315-DL). PVDF Membrane was probed with 0.1 µg/mL of Goat Anti-Human DSCAM Long Isoform Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3666) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for DSCAM at approximately 250 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 3.
DSCAM in A172 Human Cell Line. DSCAM was detected in immersion fixed A172 human glioblastoma cell line using 10 µg/mL Goat Anti-Human DSCAM Long Isoform Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3666) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue).

Human DSCAM is a member of the Ig superfamily that maps to a region in chromosome 21 associated with Down Syndrome mental retardation. It encodes a 230 kDa type I membrane protein with a large extracellular domain comprising ten C2 type Ig like domains and six fibronectin type III repeats. The intracellular domain of human DSCAM does not share significant sequence homology with Drosophila DSCAM. Human DSCAM is expressed in axonal and dendritic processes of the central and peripheral nervous system. It is involved in hemophilia interactions and has been implicated in neurogenesis. By alternative splicing, a soluble form of human DSCAM that is identical to the transmembrane form through residue 1571 has been described. The extracellular domain of human and mouse DSCAM share 98% amino acid sequence homology.
