Technical Data
CD45RO (Biotin)
The CD45RO antigen is present on most thymocytes, about 40% of resting peripheral blood T-lymphocytes and the majority of T-cells in skin reactive in ltrates and T-cell malignancies. CD45RO is also found on a subset of B-cells and some B-cell lymphomas. NK cells do not express the CD45RO antigen. It is also present on monocytes, macrophages and granulocytes. When activated with phytohemagglutinin (PHA), naive T-cells lose the CD45RA antigen and begin to express the CD45RO antigen. Therefore, anti-CD45RO may be a marker for memory T-cells.

Suitable for use in Immunohistochemistry and Flow Cytometry. Other applications have not been tested.

Recommended Dilutions:
Immunohistochemistry: Formalin-fixed, paraffin-embedded tissues; frozen sections; cell suspensions.
Flow Cytometry: 1ug to stain 1x10e6 cells.
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
