Prime editing (PE) is a next-generation gene editing technology that utilizes a Cas9 protein fused to a prime editing guide ribonucleic acid (pegRNA) to achieve high CRISPR/Cas9 editing efficiency and precision. However, the length requirement of pegRNAs at 120–250 nucleotides (nt) and their high level of secondary structure formation present analytical challenges for the purity analysis of chemically synthesized pegRNAs during development and quality control (QC).

Certain next-gen vaccines and gene therapy applications rely on the usage of adeno-associated viruses (AAV) as a delivery vehicle. To ensure the safety and efficacy of viral vector drugs, multiple critical quality attributes (CQAs) need to be well characterized.

Allergy policies for nut-free commercial flights and nut-free childcare settings are not a rare occurrence nowadays—the reason is a rise in food allergies. Nuts are the most potent allergenic foods in terms of the amount that is required to elicit an allergic reaction and the severity of those reactions.
