XIAP Tracer mF-Smac

This fluorescent XIAP tracer peptide serves as an acceptor dye for TR-FRET assays when paired with a terbium-labeled BIR domain antibody, exhibiting high-affinity binding with Kd values of 4.7 nM (BIR3) and 17.9 nM. It is a critical tool for studying apoptosis regulation and IAP protein interactions in high-throughput screening and biochemical assays.
