CD Antibodies Overview

CD Antibodies represent one of the most important classes of reagents in biomedical science. The term “CD,” or Cluster of Differentiation, refers to a standardized system for naming cell surface molecules recognized by monoclonal antibodies. CD markers are expressed across immune cells, stem cells, endothelial cells, epithelial cells, and cancer cells, where they regulate communication, adhesion, migration, and activation.

There are currently over 370 designated CD molecules, each serving as a marker for specific cell types, differentiation states, or functional responses. The Cluster of Differentiation Antibodies enable scientists to identify and isolate distinct cell populations, track immune responses, and classify hematological malignancies. Because of their breadth and diagnostic importance, CD Antibodies remain foundational in immunology, oncology, and translational research.
