IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a modified, longer-acting analog of IGF-1, a hormone central to growth and cellular development. It is a widely used research compound in cell-growth and metabolic studies. This primer is for educational reference only.
What is IGF-1 LR3?
IGF-1 LR3 is an 83-amino-acid analog of IGF-1, engineered with modifications that extend its half-life and reduce binding to IGF-binding proteins. This makes it a useful, longer-acting tool for studying IGF-1 signaling in research models. It is supplied as a lyophilized powder.
Research focus areas
- Cell growth and proliferation: studied in cell-culture and tissue-development models.
- Differentiation: examined for its role in cellular maturation pathways.
- Metabolic signaling: investigated alongside insulin and growth-factor research.
