Mouse Insulin-like Growth Factor-1 （IGF-1） is a critical polypeptide hormone that plays a vital role in growth, development, and cellular metabolism. Structurally and functionally similar to human IGF-1, it mediates the effects of growth hormone （GH） by promoting proliferation, differentiation, and survival of various cell types. Mouse IGF-1 is widely used in biomedical research to study growth regulation, tissue repair, and metabolic processes in murine models. Its applications span areas such as endocrinology, cancer research, and regenerative medicine. Recombinant mouse IGF-1, produced via E. coli or mammalian expression systems, ensures high purity and bioactivity for experimental use.
