Background: CD45RO is an isoform of CD45, a protein tyrosine phosphatase that regulates T cell receptor and B cell receptor signaling pathways. CD45RO is the shortest of the eight isoforms and is expressed on activated and memory T cells and is absent from naive T cells, making CD45RO a useful marker for differentiating T cell subsets. CD45RO is also expressed on B cell subsets, activated monocytes and macrophages. CD45RO may have prognostic value in certain cancers, including non-small cell lung cancer.

Validation: Each lot of conjugated CD45RO antibody is quality control tested by MIBIscope™ analysis of stained tissue microarrays using the appropriate positive and negative tissue field of views and are pathologist verified.

Recommended Usage: 1 uL of CD45RO antibody per 100 uL staining volume using the MIBI™ Staining Protocol.
For optimal results, antibody should be titrated for each desired application.  Suggested starting range is 1:100.
