CGE is a denaturing method that separates nucleic acids according to their sizes and used for quantitative analysis of size variants like shortmers and longmers.

Spletinvolve shortmers in which the reaction was incomplete (e.g., n-1, n-2). The yield of the target ON decreases as the number of cycles increases. Alternatively, longmers (e.g., n+1) can also be formed as well as other impurities coming from deamination or depurination, oxidation (typically guanine), and other undesirable reactions. Splet09. okt. 2024 · An addition of acidic alcohol hexafluoroisopropanol (HFIP) to the mobile phase can increase ionisation efficiency by increasing the surface charge on the ESI droplet (37). Using a combination of TEA and HFIP in the mobile phase has demonstrated the ability to resolve a range of OGN impurities, such as shortmers/longmers and P=O variants.
