CD45RO is a splice variant of tyrosine phosphatase CD45, a type I transmembrane glycoprotein. It is used to subdivide T cell populations based on their expression. The CD45RO isoform is expressed on activated and memory T cells, some B cell subsets, activated monocytes/macrophages, and granulocytes. It has also been reported to bind galectin-1 and CD22.

Each lot of antibody has been tested by flow cytometry staining. Researchers are recommended to further titrate this antibody at the optimal concentration for each specific application.
