Various methods of cell counting exist for quantifying the total number of cells in solution and calculating sample viability.
Most microvolume spectrophotometers rely on surface tension to bridge an air gap when measuring samples. Erroneous results will occur if the sample surfaces are not bridged. This note describes how the DS-11 Series eliminates these concerns using SmartPath™ technology with Bridge Testing™ verification.
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.
This blog post compares the protein concentration capabilities of Thermo Fisher NanoDrop™ One spectrophotometers and the DeNovix DS-11 Series.
