WebSep 19, 2016 · Oligonucleotides are primarily ionized via negative-ion ESI. Considering that reversed phase LC retention of these molecules is only possible with the help of basic alkylamine ion-pairing agents, acidic modifiers play a dual role in this particular case: in addition to carrying excess negative charge, they also neutralize the solution pH. WebGelatin (1 g) was dissolved in 10 mL of trifluoroethanol at a concentration of 10% weight/volume (w/v). The drugs were added to the gelatin solution so that ... were weighed and immersed in 10 mL of phosphate buffered saline (PBS) buffer (pH 7.0) with constant shaking at 37°C.
