Overlay Peak curve showing JK cells stained with CSB-RA017621MA1HU (red line) at 1:300. Then 10% normal goat serum was Incubated to block non-specific protein-protein interactions followed by the antibody (1microg/1*106cells) for 45 min at 4°C. The secondary antibody used was FITC-conjugated Goat Anti-Mouse IgG(H+L) at 1/200 dilution for 35 min at 4°C. Isotype control antibody (green line) was mouse IgG1 (1microg/1*106cells) used under the same conditions. Acquisition of >10, 000 events was performed.
