The Right Kit For Solubility Screening

By Beryl Dalton


Protein solubility kits are designed to help you in identifying the formulation that will protect your target proteins from aggregation. Solubility screening kits are also used to solubilize aggregated protein samples. The results you get from your tests will largely depend on the choice you make on the kit.

Some of the uses for the kit include quick aggregation behavior based on PH, salt and the presence of additives. It also assesses numerous conditions in a label free and parallel form. The processes require simple mixing and spinning without the use of centrifuge. This simplifies your tasks and allows you to get desired results in whichever condition.

The results obtained using the screening kits enable you to rescue reversibly aggregated protein samples. Your proteins will also not aggregate under stress. This makes them available for different tests and functions. You are provided with a dashboard with trends that make it easy to interpret results from the tests. The dashboard makes it easier to relate the results and make inferences.

Protein aggregation hinders availability of proteins for certain functions and is therefore undesirable. The main causes of aggregation include prolonged storage, vigorous stirring, elevated temperatures and the presence of ligands or protein binding partners. The best way to avoid aggregation is to make the right decision on PH, stabilization additives and salt.

The testing kit comes with buffers of PH that ranges from three to ten. You will also get solubility enhancers like polyols, amino acids, salts, reducing agents and sugars. These enhancers give precise results on the conditions in which your proteins will aggregate or de-aggregate.

A single label free experiment can test more than ninety formulations. The other six experiments are used as positive and negative control tests. Soluble proteins will go through filters while the aggregated ones will not. This is a feature that is under examination during the filtration process.

The tests using the protein solubilization kit help you to establish the conditions under which your target proteins will remain in solution form. If a well contains soluble proteins during a test, the filtration process will yield proteins. There will be no traces of proteins if they aggregate during the experiment.

The choice of conditions is determined by the results of screening. Since you can identify the conditions that facilitate the right behavior and the proteins in question, you can make an informed decision. It is used to confirm if the target substances are right for the expected results.

The benefits of using screening kits over other testing methods are numerous. Results obtained are clear and easy to interpret based on the information available in the field. The results leave no room for doubt. It takes as little as one hour to get your results. These results are certain and not based on trial and error.

The experiment does not consume large amounts of proteins and is therefore ideal for large scale testing. Reduction in protein use allows it to be matched with assay agents. A detailed report allows more conclusions and inferences to be drawn. There is no restriction on the assay that can be used.
