Figure 4

The relationship between lipid quantity and the pKa value of the LNP membrane.

Notes: (A) The relationship between the YSK12-C4 ratio in total lipids (X/70) and the pKa value for the YSK05/12-LNP membrane, theoretically simulated or experimentally measured using Equation 1 or TNS assay, respectively. (B) Determination of Y value (contribution factor) of YSK12-C4 lipid in the modified Equation 2.

Abbreviations: LNP, lipid nanoparticle; TNS, 6-(p-toluidino)-2-naphthalenesulfonic acid; pKa, acid dissociation constant.
