Cell viability is an essential measurement for cell therapy products. One of the most common tests is Trypan blue (TB) dye exclusion where blue-stained cells are counted via imaging. Typically, live and dead cells are counted based on pixel intensities of

The mRNA COVID-19 vaccines developed by Pfizer/BioNTech and Moderna represent a triumph of vaccine development. The core mRNA component of these vaccines is now almost a household name. Unbeknownst to most people, however, is that each of the two mRNA
The Nuclear Magnetic Resonance Spectral Measurement Database (NMR-SMDB) was developed for the purpose of organizing and searching NMR spectral data of protein therapeutics, linking spectra to corresponding sample information and enabling quick access to
In a rapidly growing global probiotic market, end-users have difficulty distinguishing between high quality and poor quality products. This threatens consumer and healthcare provider trust in probiotic products. To address this problem, we recommend that
We investigated using gradient elution moving boundary electrophoresis (GEMBE) and capacitively- coupled contactless conductivity detection (C4D) to assay total protein concentration using the BCA reaction. We chose this format because GEMBE is

Traditional testing methods have helped to elucidate and correlate the structure-function relationship of natural tissues and have guided the development of promising tissue-engineered medical products. From a manufacturing standpoint, such assays have
