Scientific Data Images for Human/Mouse/Rat Contactin-1 Antibody
Contactin-1 in Human Dorsal Root Ganglia.
Contactin-1 was detected in immersion fixed paraffin-embedded sections of human dorsal root ganglia using 15 µg/mL Goat Anti-Human/ Mouse/Rat Contactin-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF904) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Detection of Human, Mouse, and Rat Contactin‑1 by Western Blot.
Western blot shows lysates of human brain (cortex) tissue, human brain (cerebellum) tissue, mouse brain (cerebellum) tissue, mouse brain (total) tissue, and rat brain (total) tissue. PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human/Mouse/ Rat Contactin-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF904) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for Contactin-1 at approximately 135 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of Human and Mouse Contactin‑1 by Simple WesternTM.
Simple Western lane view shows lysates of human brain tissue and mouse brain tissue, loaded at 0.2 mg/mL. A specific band was detected for Contactin-1 at approximately 158 kDa (as indicated) using 5 µg/mL of Goat Anti-Human/Mouse/Rat Contactin-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF904) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.Applications for Human/Mouse/Rat Contactin-1 Antibody

Neutralization
Measured by its ability to neutralize Contactin‑1-mediated adhesion of the C6 rat glioma cell line [Revest, J.M. et al. (1999) Adv. Exp. Med. Biol. 468:309]. The Neutralization Dose (ND50) is typically 1-5 µg/mL in the presence of 2 µg/mL Recombinant Human Contactin‑1 Fc Chimera.

Background: Contactin-1
Contactin-1 (CNTN1) is a member of the contactin subgroup within the immunoglobulin superfamily. It was originally designated contactin in human, F3 in rodents, and F11 in chicken. Other members of this family in human include Contactin-2 (TAG-1), Contactin-5 (NB-2), and Contactin-6 (NB-3). Additional family members have been described in other species. CNTN1 shares less than 50% amino acid sequence identity with the other contactins. The human and rodent CNTN1 proteins share 96% sequence identity. The 998 amino acid mature protein contains 6 Ig-like domains and 4 fibronectin type III-like domains, and is attached to the membrane by a GPI anchor. CNTN1 is differentially expressed in numerous neuronal tissues and functions in nervous system development. It associates with two other cell-surface proteins believed to participate in signal transduction, receptor protein tyrosine phosphatase beta (RPTP beta) and Contactin-associated protein (Caspr). Reported ligands include Nr-CAM and the extracellular matrix glycoprotein, tenascin.
