Native Proteins


The demand for proteins for research purposes has significantly increased over the years. They are the central machinery in all cells and organisms and form one of the most sought after diagnostic targets. Native proteins form a large part of such research due to their unhampered activity, untagged status and wild type condition. They are of great use especially when the possibility of getting a recombinant version is compromised due to multiple reasons. United States Biological is delighted to offer numerous human/bovine/porcine origin native proteins from multiple sources like plasma, serum, erythrocytes, neutrophils, platelets and other tissues. These proteins are highly pure and can be used for multiple applications.
