Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for optimizing chromatographic purification processes for biomolecules on an industrial scale are inefficient, requiring extensive trial-and-error approaches and lacking systematic optimization, leading to suboptimal results due to the complexity of varying parameters such as pH, salt content, and buffer usage, which complicates the removal of impurities and contaminants while maintaining biological activity and yield.
Innovation Solution
A partial batch process is employed on a small scale, where the chromatography material is suspended during loading but not during elution, allowing for the optimization of loading, washing, and elution conditions, which are then reproducible on a larger scale, enabling simultaneous variation of multiple parameters to determine optimal chromatography conditions for biomolecule purification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional trial-and-error methods are used to optimize chromatographic purification processes, then comprehensive parameter testing can be performed, but the process requires extensive time and numerous preliminary tests
Solution Approach 1:
The patent creates a simplified copy model using multi-well plates that replicates the essential chromatographic purification process at a reduced scale. This copying approach allows systematic optimization of purification parameters without requiring extensive time and resources for full-scale trials, directly resolving the contradiction between achieving manufacturing precision and reducing time loss.
2Manufacturing precision
If multiple parameters are varied simultaneously in traditional optimization, then comprehensive optimization can be achieved, but the complexity of the process increases significantly
Solution Approach 1:
The patent segments the optimization process by dividing it into distinct phases: first optimizing binding conditions, then elution conditions, and finally polishing conditions. Each phase focuses on specific parameters rather than varying all parameters simultaneously, thereby achieving comprehensive optimization while maintaining manageable process complexity.
Solution Approach 2:
The patent introduces a new dimension of optimization by implementing a multi-stage sequential approach that adds temporal structure to the parameter optimization process. This dimensional change allows systematic exploration of parameter space without overwhelming complexity, as each stage builds upon the previous optimization results.
3Loss of substance
If small-scale screening is used to optimize chromatography conditions, then material usage is minimized, but the results may not be reproducible on larger industrial scale
Solution Approach 1:
The patent performs preliminary optimization actions on a small scale using multi-well plates to establish optimal conditions before scaling up to industrial production. The segmented optimization approach ensures that conditions are systematically determined in advance, making the results reliably transferable to larger scales while minimizing material consumption during the optimization phase.

AI summary
The invention relates to a process for finding suitable parameters for the chromatographic purification of biomolecules. The process consists of equilibration, loading, washing and elution steps, wherein this sequence of steps is carried out in the partial batch process. The parameters determined in small, preferably a plurality, of parallel batches give information on the chromatography conditions under which a given biomolecule may be optimally purified by column chromatography, if appropriate even on a relatively large scale.
