Used in immunological research and therapeutic development targeting the TLR2 (Toll-like receptor 2) pathway. It modulates innate immune responses by blocking TLR2 activation, which is involved in inflammation triggered by bacterial components like lipoproteins. Investigated for treating autoimmune diseases, chronic inflammatory conditions, and certain cancers where TLR2 signaling contributes to disease progression. Enables selective immune modulation, making it a candidate for targeted biologic therapy. Also used as a reference standard in assay development and antibody validation.
