Native proteins retain the functional characteristics displayed by a protein in vivo. The process includes extracting proteins directly from the source while preserving correct protein folding, three-dimensional shape and post-translational modifications.

Yashraj Biotechnology has access to a wide range of human fluids and tissues and this is where we extract native proteins from. Our selection of high quality native proteins are available in a variety of purities and formulations. Moreover, these are linked to disease areas such as cancer, heart and kidney disease, infectious diseases and autoimmunity.
