Current methods for finding the equilibrium dissociation constant, Kd, of protein-small molecule complexes have inherent sources of inaccuracy.We introduce “Accurate Kd via Transient Incomplete Separation” (AKTIS), an approach that is free of kno

The measured quantum yield of Yb-2,4-dimethoxyhematoporphyrin (Yb-DMHP) in DMSO was 0.8%. It was found that molecular oxygen did not quench luminescence of the metal ion in Yb-DMHP, which was a diagnostic advantage while using this complex in practic

Accurate quantitation of microRNA (miRNA) in tissue samples is required for validation and clinical use of miRNA-based disease biomarkers. Since sample processing, such as RNA extraction, introduces undesirable biases, it is advantageous to measure m
