Can RIA be used for modern drug discovery?
Indeed. The principles underlying RIA—precise quantification of specific molecular interactions—are foundational to many modern techniques, including those used in drug discovery. While newer technologies like ELISAs have become more prevalent for routine screening, the core concept of using labeled molecules and specific binding agents to detect and quantify targets remains. Understanding the precise binding affinity and concentration of drug candidates or biomarkers is paramount. If you can't measure it accurately, how can you possibly understand its effect or optimize its development? The need for precision never diminishes.
