Insights

A new monoclonal antibody, K9BYU, successfully targets canine neural-cell adhesion molecule (N-CAM). This antibody recognizes multiple N-CAM isoforms in canine brain tissue, proving useful for N-CAM research.

Area of Science:

  • Immunology
  • Neuroscience
  • Molecular Biology

Background:

  • Neural-cell adhesion molecule (N-CAM) plays a crucial role in neuronal development and function.
  • Understanding canine N-CAM expression and function is vital for comparative neuroscience and translational research.

Purpose of the Study:

  • To generate and characterize a novel monoclonal antibody, K9BYU, specific for canine neural-cell adhesion molecule (N-CAM).
  • To evaluate the utility of K9BYU as a research tool for studying canine N-CAM.

Main Methods:

  • Generation of monoclonal antibody K9BYU using recombinant canine N-CAM extracellular domain expressed in Escherichia coli.
  • Immunoreactivity confirmation via Western blotting against insect cell-expressed canine N-CAM.
  • Analysis of canine brain tissue using Western blotting to detect N-CAM isoforms.

Main Results:

  • K9BYU demonstrated immunoreactivity to insect cell-expressed canine N-CAM.
  • Western blotting of canine brain tissue revealed that K9BYU detects three major N-CAM isoforms (N-CAM-120, -140, and -180).
  • These detected isoforms correspond to known major isoforms in human and mouse N-CAM.

Conclusions:

  • The monoclonal antibody K9BYU is a specific and effective tool for detecting canine N-CAM.
  • K9BYU facilitates the study of canine N-CAM isoforms, aiding comparative neuroscience research.
