Searching for carrier-free proteins

Use the Formulation filter to find carrier-free proteins

When purchasing some proteins from vendors, they may include a protein like BSA to improve stability. However, carrier proteins may interfere with some experiments and applications (e.g. positive control on a Western Blot), so you can filter for products that vendors label Carrier Free in the Formulation filter. To expand your results, you can also consider evaluating products and formulations that are BSA-free too, depending on your experiment needs.
