Overview
The development of novel gene-editing approaches goes beyond the treatment of diseases or their symptoms. However, analytical solutions for CRISPR/Cas9 analysis need to keep up with the demands of these new approaches.
Leverage highly sensitive techniques for characterizing large synthetic guide RNAs and in vitro transcribed RNA products, and understand low-abundance post-translational modifications (PTMs) of Cas9 proteins and CRISPR/Cas9 effects on the proteome. With dedicated analytical solutions, personalized medicine is only a step away.

pegRNA analysis with CGE
More sophisticated, chemically synthesized gRNAs are in development with the goal of increasing efficiency and specificity of CRISPR/Cas9 gene editing. One of these newly emerging classes is pegRNA with sizes ranging from around 120–250 nucleotides (nt).
The length and associated risk of secondary structure formation, however, pose challenges for the analytical assessment of its purity.
Move beyond these boundaries of CRISPR/Cas9 analysis and confirm size and purity for large pegRNA with confidence. Rely on high resolving power and repeatability to separate your products from impurities with similar properties.
