UV-Vis spectroscopy is widely used for measuring sample concentrations in gene therapy development, although it poses challenges such as dilution errors and lengthy sample preparation. Variable pathlength technology (VPT), also known as slope spectroscopy, is a UV-Vis-based technique that can be utilized to overcome these hurdles by measuring absorbance changes over variable pathlengths, eliminating dilution and baseline correction requirements. In this article, three case studies are explored to confirm the specificity, accuracy, reproducibility, and linearity of SoloVPE® for encapsulated mRNA analysis.
