Three in One: Concentration, Size & Zeta Potential measured on sub-visible protein suspensions
The preparation of high-value biological material, such as proteins, requires a multi-step procedure of separation and purification. Each step must be optimized to reach full efficiency of yield. Two key parameters for monitoring yield are protein size distribution and aggregate concentration. Both measures must be monitored over wide ranges. The combination of two powerful techniques, DLS & NTA, gives valuable information for biological formulation.
