Immunohistochemistry / IHC Antibody CD Molecule

Background

Immunohistochemistry is the localization of antigens or proteins in tissue sections by the use of labeled antibodies as specific reagents through antigen-antibodyinteractions. Immunohistochemical antibody is widely used in the diagnosis of abnormal cells such as those found in cancerous tumors. Immunohistochemical antibody is also widely used in basic research to understand the distribution and localization of biomarkers and differentially expressed proteins in different parts of a biological tissue.
The cluster of differentiation (or cluster of designation), often abbreviated as CD, is a protocol used for the identification and investigation of cell surface molecules present on white blood cells. The cluster of differentiation nomenclature was proposed for the classification of the many monoclonal antibodies generated by different laboratories around the world against epitopes on the surface molecules of leukocytes. Since then, the use of cluster of differentiation has expanded to many other cell types.
