POLYCLONAL ANTIBODIES (pAb)
They are natural multispecific antibodies recognizing dozens of different epitopes on several antigens. They are not sensitive to individual mutations or mutation escape mechanisms. Polyclonal antibodies are different from and complementary to monoclonal antibodies, with a therapeutic advantage in the main indications where they present a different mode of action. Their broad spectrum avoids off-target toxicity and makes them ideal candidates for attacking complex or highly mutating targets.
