The Right Kit For Solubility Screening

By Beryl Dalton


Protein aggregation affects their availability for certain functions. This calls for solubility screening to establish the formulations or conditions that will protect your proteins. The choice of kit will determine the comprehensiveness or intensity of the results you obtain. The protein samples are solubilized during testing depending on expectations.

Aggregation properties and capabilities are easily detected by using PH, salt and other additives. A label free form and a parallel form will give an idea about the conditions being examined. Testing does not require the use of centrifuges. The desired results are obtained through simple mixing and spinning of the agents being tested. This increases the range of circumstances that can give desired results.

Screening kits allow you to rescue protein samples that are reversibly aggregated. The kit also performs incredibly well in protecting proteins from aggregating when under stress. This means that they will be available in the form desired. The trends used on such kits are easily found on the dash board. Your results are easily related to what is conventionally known.

The process of protein aggregation is undesirable because it hinders certain functions. Some of the conditions that lead to aggregation include addition of ligands, protein binding partners and elevated temperatures. Prolonged storage and vigorous stirring also cause aggregation. When the right decision on salt, PH and stabilizing additives is made, aggregation can be avoided.

With a PH range between 3 and 10, the screening kit offer sufficient buffer. It also comes with solubility enhancers such as sugars, salts, amino acids, reducing agents and polyols, among others. The results are clear and precise which allows you to identify aggregating and non-aggregating proteins.

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.

Protein solubilization tests give the conditions under which your proteins will not aggregate. From such tests, it is observed that filtration processes yield proteins when they are in soluble form. They are available in aggregated form if the test does not show any traces of proteins.

The results of screening tell of the best conditions that the proteins will perform. It gives you an opportunity to isolate proteins that behave well for your intended purpose and those that cannot fit your intentions. With such results, you can scale up the use without fear since you have confirmed the results.

You stand to enjoy numerous benefits using this kit than other methods available in the market. It produces clear results that are easy to interpret based on the conditions you are testing. It also is fast which allows you to get results within an hour. This places it at a better position compared to the trial and error methods used in other quotas.

The approach substantially reduces protein consumption during experiments. Because of this reduction, it is easy to match the target proteins with the assay. A detailed report is received allowing you to make many more inferences and conclusions. The kits do not restrict the assay that may be used during testing.
