IGF-1 LR3 (Insulin-Like Growth Factor-1 Long R3) is a modified version of IGF-1 designed for increased stability and extended activity in research environments.
This modification allows researchers to study prolonged biological activity without rapid peptide breakdown.
Compared to standard IGF-1:
These structural changes enhance bioavailability and extend the peptide’s functional half-life.
IGF-1 LR3 interacts with the IGF-1 receptor (IGF-1R), activating intracellular signaling pathways involved in:
These pathways are essential for studying growth-related cellular responses in controlled environments.
Because of its reduced affinity for binding proteins, IGF-1 LR3 remains more bioavailable in controlled environments compared to native IGF-1.
Higher bioavailability allows for more consistent and measurable research outcomes.
In laboratory settings, IGF-1 LR3 is commonly studied for:
Its extended activity makes it suitable for long-duration experiments and advanced research studies.
