Figure 8

Confirmatory experiments using binding assays for molecules able to interact with Plm II in the selected extracts. Affinity chromatography profiles of extracts: P31 (A); and P32 (B) with a HiTrap™ Plm II-Sepharose HP resin. Arrows indicate the addition of elution buffer. (C) Sensorgrams from the SPR biosensor-based assay for the interaction of extracts P11, P31 and P32 with Plm II. (D) Titration curve of purified PhPI with (pepstatin A-titrated) Plm II used to determine the concentration of active inhibitor. (E) Concave dose–response curve for the estimation of Kiapp of PhPI with Plm II.
