Part-Coated CEC for β2-AR Binding Constants
2026-09-20
Liu and colleagues developed a part-coated open-tubular capillary electrochromatography method for estimating binding constants between β2-adrenergic receptor and seven drug or botanical samples. By relating receptor-coating length to apparent electrophoretic mobility, the approach reduces protein consumption, avoids detection-window interference, and supports affinity screening with computational interpretation.
