At BPS Bioscience we hold our products to rigorous QC standards—only those proteins ≥90% purity as measured by gel filtration receive the HiP™ status. The data below demonstrates the importance of checking aggregation levels. While both of these PD-1 proteins are over 90% pure by SDS-PAGE and Coomassie staining, they exhibit very different profiles by FPLC. The protein on the left shows significant aggregation, while the protein on the right is less than 5 % aggregated. Only the protein on the right would earn BPS’s HiP™ distinction.
With HiP™ proteins from BPS, you can be confident in your binding assays knowing that you are working with soluble, functional, native protein. View our full line of HiP™ proteins or request a quote today.
