Novel Method for Creating and Modifying Stable Cell Lines for Enhanced Proteomic Analysis
Unmet Need Characterizing the composition and function of protein complexes can facilitate the understanding of key cellular processes. Indeed, the global proteomics market was estimated to be USD 25.9 billion in 2021. However, the analysis…
Methods and compositions to sense m6A RNA modifications using a genetically encoded sensor
Unmet Need Gene expression is highly regulated through the addition of chemical modifications to RNA molecules. One such modification is methylation of adenosine residues to form m6A, a modified nucleotide which is found in thousands…
