CD45RO antibodies, human

CD45RO antibodies, human

Clone: REA611 | Dilution: 1:11
Clone REA611 recognizes the human CD45RO antigen, a 180 kDa single-chain membrane glycoprotein, which is an isoform of CD45. CD45RO is expressed by most thymocytes, activated and memory T cells, granulocytes, B cell subsets, and monocytes. CD45RO binds to galectin-1 and CD22. CD45RO antibodies are commonly used in combination with antibodies against CD45RA to discriminate memory T cells from naive T cells.
Additional information: Clone REA611 displays negligible binding to Fc receptors.

REAfinity clone is tested against different known clones, in a blocking experiment, to identify whether they recognize completely overlapping (++), partially overlapping (+), or completely different epitopes (-). In a blocking experiment, cells are incubated with an excess of purified unconjugated REAfinity clone followed by staining with conjugated form of the other known clones.
