Overview

  • Aggregation is a major challenge in biologics development, and can be assessed using isothermal chemical denaturation.
  • Gibbs Free Energy values determined for different concentrations of protein using SUPR-CM.
  • High-throughput capabilities of SUPR-CM allowed for rapid processing of samples.
  • Aggregation propensity measured for the same protein in two different buffers (phosphate and acetate).
  • Evidence showing phosphate significantly increases propensity for the unfolded protein to aggregate.
  • Acetate buffer showed no statistically significant change in ΔG° values, with over 4x reduction in aggregation propensity when compared to the phosphate samples.
