Description

Long arginine 3-IGF-1, abbreviated as IGF-1 LR3 or LR3-IGF-1, is a synthetic protein and lengthened analogue of human insulin-like growth factor 1 (IGF-1). It differs from native IGF-1 in that it possesses an arginine instead of a glutamic acid at the third position in its amino acid sequence ("arginine 3"), and also has an additional 13 amino acids at its N-terminus (MFPAMPLLSLFVN) ("long"), for a total of 83 amino acids (relative to the 70 of IGF-1).

IGF-1 LR3, commonly shorted as IGF, is a modified synthetic analog of Insulin-like Growth Factor 1. Thanks to structural optimization, it barely binds to IGFBPs and owns a prolonged half-life. It activates IGF-1R related signaling pathways to support cell proliferation and protein metabolism research. Popularly used in cell culture, tissue repair and muscle-related laboratory studies. We provide high-purity lyophilized IGF-1 LR3 powder for research purposes only.
