ab68565 reacts with CD53 exclusivelly expressed on leukocytes; it is not present on platelets, red blood cells and non-hematopoietic cells. This antibody reacts also with deglycosylated molecule (molecular weight of the antigen is reduced by 15 kDa using endoglycosidase F).
Overlay histogram showing peripheral blood lymphocytes stained with ab68565 (red line). The cells incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab68565, 1 µg/1x106 cells) for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 FITC (2 µg/1x106 cells ) for 30 min at 22°C. Acquisition of >5,000 events was performed.
