Background/Objectives: Protein aggregation, particularly the aggregation of antibody-based drugs, has long been a significant challenge in downstream processes and formulation. While inhibitory effects excipients on have extensively studied using early experimental characterization methods, complete formulation research requires amounts antibodies time, resulting high costs. Methods: This study proposed quick small-scale position-restrained simulation method which elucidated mechanism reversible self-association (RSA) influence RSA under different conditions. We also validated rationality rapid simulations through long-term (>1 μs) large-scale (>1,000,000 atoms) simulations. Results: Through combing with simple stability characterization, monomer residual content trend shown concentration changes after thermal incubation were found to be similar those observed Additionally, by was characterization. Conclusions: Simulations experiments revealed showed consistent trends, providing better understanding for research.

Abstract Over the years, production of eggs has increased tremendously, with an estimated global egg 9.7 billion by 2050. Further processing shell to products gained growing popularity. Liquid yolks, innovative form replacement, still suffer from short shelf‐life issues, and freezing been applied maintain freshness. An undesirable phenomenon called “gelation” was found during frozen which attracted numerous scholars study its mechanism quality control methods. Therefore, we comprehensively reviewed history studies on including procedure, fundamentals freezing, gelation mechanism, factors affecting behaviors, techniques behaviors yolks. Reporting procedure yolks will give readers a better understanding science technological aspects Furthermore, comprehensive summary yolk gel formation induced freeze–thawing relevant provide insights researchers manufacturers in field processing.

Protein formulation development relies on the selection of excipients that inhibit protein–protein interactions preventing aggregation. Empirical strategies involve screening many excipient and buffer combinations by physicochemical characterization using forced degradation or temperature-induced stress, mostly under accelerated conditions. Such methods do not readily provide information inter- intramolecular responsible for effects excipients. Here, we describe a combined experimental computational approach investigating effect protein–excipient stability, which allows identification preferential interaction sites thus can aid in to be experimentally screened. Model systems composed two marketed therapeutic IgG1 monoclonal antibodies with identical Fc domain sequences, trastuzumab omalizumab, were investigated commonly used arginine, glutamate, equimolar arginine/glutamate mixtures. Protein–excipient studied all-atom molecular dynamics (MD) simulations, show accumulation at specific antibody regions. Preferential excipient-interaction particularly found charged aromatic residues complementary-determining regions, more pronounced arginine contacts omalizumab than trastuzumab. These findings are line stabilizing observed long-term storage stability study. Furthermore, aggregation solubility propensity predicted silico tools align identified MD suggesting different mechanisms play.
