Used in targeted cancer therapies, particularly for ovarian and non-small cell lung cancers that overexpress the folate receptor alpha (FOLR1). This antibody serves as a key component in antibody-drug conjugates (ADCs), where it delivers cytotoxic agents directly to cancer cells, minimizing damage to healthy tissues. Its high specificity enables improved therapeutic efficacy and reduced side effects. Also utilized in diagnostic applications to detect FOLR1 expression in tumor tissues, aiding in patient selection for FOLR1-targeted treatments. Plays a role in research settings for studying folate receptor biology and drug internalization mechanisms.
