IGF-1 LR3 CAS NO.946870-92-4

 In fact, one substitution and additional 13 amino acids to make this variants of insulin-like proteins the most effective and stable, as well this feature prolong its half-life period and doesn’t allow binding to other proteins.

Long R3 IGF-1 (Insulin-like Growth Factor -1) is a polypeptide hormone that structurally and molecularly, shares some properties with insulin, which is where it got “Insulin-like” from in its nomenclature. IGF-1’s primary roles include long bone growth in kids, and in adults it affects the growth and repair of muscle tissue. Regular IGF has a half life of only about 20 minutes, where as the modified version called LR3 is altered some to prevent deactivation by binding proteins in the blood and extends the half life to about 20 hours making it able to be more effective.

 In fact, one substitution and additional 13 amino acids to make this variants of insulin-like proteins the most effective and stable, as well this feature prolong its half-life period and doesn’t allow binding to other proteins.
