• 

  IP experiment of rat brain using 87612-1-RR (same clone as 87612-1-PBS)

  IP result of anti-CNTN1 (IP:87612-1-RR, 4 ug; Detection: 87612-1-RR 1:5000) with rat brain tissue lysate 1720 ug. This data was developed using the same antibody clone with 87612-1-PBS in a different storage buffer formulation.

• 

  Affinity of 87612-1-RR

  Biolayer interferometry (BLl) kinetic assays of 87612-1-RR against Human CNTN1 were performed. The affinity constant is 1.72 nM.

Background Information

Contactin-1 (CNTN1), also known as Glycoprotein gp135 or Neural cell surface protein F3, is a neuronal cell adhesion molecule of the immunoglobulin superfamily (PMID: 3049624). It consists of six Ig domains, four fibronectin-like motifs, and a glycosylphosphatidylinositol (GPI)-moiety. Expressed by the central and peripheral neurons, CNTN1 contributes to the formation and function of neuronal connections. It plays a role in axon extension and formation of septate-like junctions between axons and myelinating glial cells (PMID: 23724143). In addition, acting as a ligand for Notch, CNTN1 initiates a NOTCH/DTX1 signaling pathway that promotes oligodendrocyte maturation and myelination (PMID: 14567914).
