Comparison between the traditionally used TentaGel resin and our glass beads for evaluating nonspecific protein adsorption. It can be observed for peptides like EKEKEKEK that TentaGel resins are susceptible to swelling and protein entrapment, where the glass beads provide a more rigid surface that represents the chemistry of the surface more accurately.
