Description
IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is an 83-amino-acid recombinant analog of IGF-1, modified with an additional 13-amino-acid N-terminal extension and an Arg-3 substitution that reduces binding to IGF-binding proteins relative to native IGF-1. Molecular formula: C400H625N111O115S9; molecular weight: approximately 9,111-9,117 Da; CAS 946870-92-4.
Research on IGF-1 LR3 has examined its prolonged bioactivity at the IGF-1 receptor due to decreased IGFBP sequestration, and its downstream PI3K/Akt and MAPK signaling pathways in cell culture and animal models.
Supplied as a lyophilized powder for reconstitution, each batch is analyzed by HPLC to confirm purity and identity.
For laboratory research use only. Not for human or veterinary use, and not intended for diagnostic or therapeutic application.
