Automated, high-resolution cellular retention and uptake studies in vitro

• This report describes an automated method for the measurements of cellular retention and uptake of radiolabeled proteins interacting with cell-surface receptors on intact cancer cells. A complete uptake and retention measurement was performed in one cell dish using a rotating radioimmunoassay (RIA) principle. Compared to common manual measurements, rotating RIA saved both labor time and reagents and provided real-time binding traces with superior time-resolution. The rotating RIA retention profiles for different interactions agreed with retention times reported in the literature.
