Compared with gene therapies, protein therapeutics are more convenient and safe with less probability of interfering with normal biological processes and causing adverse effects. Because of the great success in clinics, protein-based therapeutics enjoy unprecedented recognition of their potential, which has become an important growing category of biologic medicines in pharmaceutics.
