The DeNovix DS-11 Series Spectrophotometer / Fluorometer offer best-in-class limits of detection, the broadest dynamic range, intuitive ease of use and powerful networking features that are superior to the Thermo Fisher NanoDrop™ One spectrophotometer. This note presents a comparison of features and side-by-side instrument performance

Fluorometric sample quantification is a routine application in molecular biology labs however it is important to employ a number of best practices to ensure reliable results. This document outlines some of the key considerations.

The DeNovix DS-11 Series Peptide app enables protein or peptide concentration determinations based upon absorbance values at either 215 nm or 205 nm. Data is presented for polymyxin B demonstrating the DS-11 can be used to determine the concentration of peptides over a wide dynamic range.

Purity ratios are routinely used to identify contamination in samples when quantifying using UV-Vis. Understanding their utility and threshold values is essential to correct interpretation.
