Biosimilar antibodies are research-use-only (RUO) recombinant antibodies, which incorporate the same variable region sequence as the therapeutic antibodies. Although they are not produced by the same method as for therapeutic purposes, these biosimilar antibodies are commonly used to study the effects of original therapeutic antibodies without the necessity to source costly pharmaceutical-grade reagents.
