Ammonium sulfate solutions are commonly used in protein purification workflows, particularly for salt-induced precipitation (e.g., “salting out”). By increasing ionic strength, ammonium sulfate reduces protein solubility, enabling selective fractionation and concentration of target proteins.

These solutions are widely used in biochemistry, molecular biology, and bioprocessing applications, including protein purification, enzyme stabilization, and sample preparation. Because ammonium sulfate is highly soluble and doesn’t greatly perturb protein structure, it remains a standard reagent for maintaining protein activity during purification workflows.

We supply ammonium sulfate solutions as ready-to-use formulations, eliminating in-house preparation and reducing variability across protein purification workflows. Each solution is manufactured to precise specifications to ensure consistent ionic strength and reliable precipitation performance.

Our off-the-shelf ammonium sulfate solutions, including saturated, 7.5M, 25%, 3.8M, and 1M solutions, are designed to integrate seamlessly into laboratory and manufacturing operations, from small-scale protein purification to method development and process optimization. All products are manufactured under strict quality control standards to ensure concentration accuracy and lot-to-lot consistency. We can also efficiently produce custom ammonium sulfate solutions to your exact specifications, including modified concentrations and container formats to meet specialized research or manufacturing requirements.
