Native Proteins

native proteins banner

Native proteins are proteins purified from its natural source which includes whole blood, serum, and plasma from human, animal or reptiles. In addition, microbes and non-microbial substances such as egg white, animal skin are also good source of native proteins. Native proteins undergo the natural in-vivo modifications such as cleavage of precursor proteins, disulfide bond formation, glycosylation or phosphorylation and maintain their complex 3-D structure, hence their behavior pattern is similar to their in-vivo behavior which makes it an ideal candidate for many applications.
