Targeting accuracy

Definition

Targeting accuracy refers to the precision with which therapeutic agents, such as genes or drugs, are delivered to specific cells or tissues in the body. High targeting accuracy is crucial in gene therapy, as it ensures that the intended cells are treated without affecting surrounding healthy tissues, minimizing side effects and maximizing therapeutic efficacy.

5 Must Know Facts For Your Next Test
