GMP mRNA Manufacturing

The Signification of GMP Manufacturing

Good manufacturing practice (GMP) is an aspect of quality assurance consisting of processes, procedures and documentation. GMP ensures medicinal products are consistently produced and controlled to the quality standards appropriate to their intended use for humans or animals.

A stable and reliable supply of GMP-grade biologics is vitally important to all phases of a product’s lifecycle, including the preclinical, phase 1, phase 2, phase 3 and commercial stages.
