Fig. 1. Gel retardation assay for mRNA encapsulation efficiency of LNPs at various N/P ratios.
The encapsulation efficiency of various LNP formulations was determined using gel retardation assay. For each LNP, encapsulation was performed using 100 ng of mRNA at various N/P ratios for 30 min at room temperature. This was followed by gel lag on a 1.2% agarose gel at 100 V for 20 min. The mRNA bands were then stained with SYBR Green II diluted 1:10,000 in TBE buffer and measured using UV illumination.
