It is produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage. When ready to transition into later clinical phases, we also offer a custom GMP protein service that tailors to your needs. We will work with you to customize and develop a GMP-grade product in accordance with your requests that also meets the requirements for raw and ancillary materials use in cell manufacturing of cell-based therapies.

Protocol
背景（Background）
Growth hormone (GH or GH-N) is also known as Somatotropin, Pituitary growth hormone. GH belongs to the somatotropin/prolactin family. Growth hormone (GH) may form monomer, dimer, trimer, tetramer and pentamer, by disulfide-linked or non-covalently associated, in homopolymeric and heteropolymeric combinations. GH can also form a complex either with GHBP or with the alpha2-macroglobulin complex. Growth hormone (GH) plays an important role in growth control. Its major role in stimulating body growth is to stimulate the liver and other tissues to secrete IGF-1. It stimulates both the differentiation and proliferation of myoblasts. It also stimulates amino acid uptake and protein synthesis in muscle and other tissues.
