Pharmaceutical Sciences

Background:

Protein-based biologics offer low toxicity and high target specificity, making them ideal for drug development.
Elevated concentrations are often required for therapeutic applications, but insufficient protein solubility presents a significant challenge.
Current methods for protein solubility screening are time-consuming and require substantial protein amounts.

Purpose of the Study:

To develop an ultrahigh-throughput microfluidic platform for rapid protein solubility screening.
To enable quantitative comparison of formulation excipients and their combinatorial effects on protein solubility.
To facilitate the screening of large protein libraries, including the impact of mutations and pH on solubility.

Main Methods:

An ultrahigh-throughput microfluidic platform was designed for protein solubility screening.
The platform integrates sample preparation, incubation, and measurement within minutes.
The system requires minimal protein input (20 microg) and generates a high volume of data points (10,000).

Main Results:

The microfluidic platform demonstrated a >10-fold improvement in protein reduction and a 1000-fold increase in data points compared to previous methods.
Quantitative comparisons of various formulation excipients (e.g., sodium chloride, polysorbate, histidine, arginine, sucrose) were performed.
The study successfully assessed the combinatorial effects of multiple additives, optimal pH, and the impact of mutations on protein solubility.

Conclusions:

The developed microfluidic platform significantly accelerates protein solubility screening.
This approach reduces material and time costs, enabling comprehensive multidimensional solubility optimization.
The platform streamlines biotherapeutic drug development and enhances understanding of protein solubility and excipient interactions.
