Improving biosensor assay development by determining sample quality with Tycho NT.6

Abstract

Surface plasmon resonance (SPR) is an optical methodology widely used to detect and quantify molecular interactions. SPR is considered the gold standard for quantification of protein interactions, but SPR assay optimization can be technically challenging, time-consuming and costly. Tycho NT.6 quickly analyzes different conditions typically tested during optimization of an SPR assay. The Tycho NT.6 system is simple to use and enables researchers to make better-educated decisions in developing and optimizing their binding-interaction assays.
