Lipid nanoparticle (LNP)-formulated mRNA vaccines were rapidly developed and deployed in response to the SARS-CoV-2 pandemic. Due to the labile nature of mRNA, identifying impurities that could affect product stability and efficacy is crucial to the long
An aliquot (20 μL) of the aqueous peptide stock solution (10 mg/mL) was added to 1 mL of 25% solution of fresh human blood plasma in water at 37 °C. Aliquots (50 μL) were withdrawn and added to 5 μL of pure trifluoroacetic acid (TFA) at different time intervals...

:ammonium hydroxide, to elute peptides. The SCX SPE removes the detergent (i.e., CHAPS) but the ammonium salts still need to be removed before iTRAQ labeling. C-18 SPE columns (SUPELCO Discovery, 50 mg) were then employed to remove the salts, using a 0.1% trifluoroacetic acid (TFA)...
The obtained peptides were cleaved from the resin using a trifluoroacetic acid (TFA)/phenol/ triisopropylsilane/H2O mixture (88:5:2:5,v/v) [38]. The purity of the synthesized peptides was checked on RP-HPLC Jasco LC System (Jasco, Japan) equipped with Supelco Wide Pore C8 column (8 ...
