Background:

Separating intact proteins from proteolytic fragments presents significant challenges due to shared properties.
Existing purification methods are often time-consuming and prone to non-specific binding, allowing further protein degradation and aggregation.

Purpose of the Study:

To develop a rapid and efficient method for separating full-length proteins from their proteolytic degradation products.
To address the limitations of conventional protein purification techniques in preserving protein integrity.

Main Methods:

Investigating the aggregation behavior of proteolytic products for two distinct proteins.
Implementing a filter flow-through purification strategy to exploit differential aggregation.

Main Results:

Demonstrated that proteolytic fragments aggregate for the studied proteins.
Achieved rapid separation of full-length protein from proteolytic products via filter flow-through purification.
Observed substantial enhancement in protein purity using this novel approach.

Conclusions:

Filter flow-through purification is an effective method for separating intact proteins from aggregated proteolytic fragments.
This rapid technique offers significant advantages over traditional methods, particularly for sensitive proteins.
The approach shows promise for purifying intrinsically disordered proteins prone to aggregation.
