GMP refers to "Good Manufacturing Practice," which is a set of
mandatory standards for pharmaceutical, food, and other industries
to ensure the quality and safety of products. It requires companies
to take care of raw materials, personnel, facilities and equipment,
production processes, packaging and transportation, quality
control, etc. All must meet mandatory standards. GMP stable cell
lines refer to stable cell lines obtained under conditions that
comply with GMP standards and are used to produce high-quality
pharmaceuticals, especially biopharmaceuticals. GMP stably
transduced cell lines need to go through screening, identification,
and quality control to ensure that their performance is stable,
reproducible, and in compliance with GMP requirements. During the
GMP cell line construction process, comprehensive virus detection,
cell bank establishment, cell line identification, and other steps
are also required to ensure the safety and quality of the
product.
