The ability of a drug conjugate to target both antigen-positive cells and neighbouring antigen-negative cells is called a bystander effect. To assess the bystander activity of a drug conjugate, a mixture of antigen-positive and antigen-negative cells are incubated in the presence of compound. After 6 days in culture, the remaining cell population is analysed by flow cytometry. Antigen-positive and antigen-negative viable cells are identified, counted and compared to untreated samples.
