Cultured ROR1+ JeKo-1 cell line and 3 ROR1+ primary CLL patient samples were harvested and incubated at 4°C with UC-961 or VLS-101 followed by a fluorophore-conjugated secondary antibody and viability staining, and then analyzed by flow cytometry. The table provides the EC50 of the viable cell population. Comparable data were obtained from at least 3 independent experiments.
