![Human peripheral blood lymphocytes stained with ab9089 (red line). Human whole blood was processed using a modified protocol based on Chow et al, 2005 (PMID: 16080188). In brief, human whole blood was fixed in 4% formaldehyde (methanol-free) for 10 min at 22°C. Red blood cells were then lyzed by the addition of Triton X-100 (final concentration - 0.1%) for 15 min at 37°C. For experimentation, cells were treated with 50% methanol (-20°C) for 15 min at 4°C. Cells were then incubated with the antibody (ab9089, 0.1μg/1x106 cells) for 30 min at 4°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgM (mu chain) (ab97007) at 1/500 dilution for 30 min at 4°C. Isotype control antibody (black line) was mouse IgM [ICIGM] (ab91545, 1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control.
