Reports from R.I. Stefan-van Staden and Co-Researchers Add New Data to Findings in Oligopeptides

June 27, 2014

By a News Reporter-Staff News Editor at Science Letter -- Current study results on Peptides have been published. According to news reporting originating in Bucharest, Romania, by NewsRx editors, the research stated, "A novel enantioselective surface plasmon resonance (SPR) sensor based on a self-assembled monolayer of C-60 fullerene as the chiral selector is proposed."

The news reporters obtained a quote from the research, "A binding assay, apparent affinity constant, and apparent dissociation binding constant were used to analyze and study the enantioselectivity of C-60 fullerene-glutathione film for L-histidine, which was chosen as the model analyte. The apparent affinity constant for the complex formed by L-histidine with C-60 fullerene-glutathione film was 5.2 x 10(9)M(-1)."

According to the news reporters, the research concluded: "The proposed SPR sensor can be used for the assay of L-histidine in the 10(-10) - 10(-7)mol/L concentration range. Chirality 26:129-131, 2014."
