IGF-1 LR3 – Insulin-Like Growth Factor-1 Analog (Long-Acting Research Peptide)
Compound Name: Insulin-Like Growth Factor-1 LR3 (IGF-1 LR3)
Classification: Research Peptide – IGF-1 Analog
Description:
IGF-1 LR3 is a synthetic analog of insulin-like growth factor-1 engineered with structural modifications that extend stability and reduce binding affinity to IGF-binding proteins in laboratory research environments. These modifications make IGF-1 LR3 a commonly studied compound in controlled in-vitro and biochemical research models where sustained peptide–receptor interaction is required.
In laboratory research settings, IGF-1 LR3 is examined for its involvement in IGF-1 receptor–mediated signaling pathways, intracellular communication networks, and peptide-regulated cellular processes. Researchers frequently utilize this compound in cellular and molecular model systems to explore growth factor signaling, protein synthesis regulation, and mechanisms related to cellular growth and metabolic pathway modeling.
Due to its extended activity profile and modified structure, IGF-1 LR3 is often selected for research applications that focus on long-duration signaling studies, receptor-binding dynamics, and controlled investigation of growth factor–associated biochemical pathways.
This compound is supplied in lyophilized (freeze-dried) powder form to support stability and consistency in controlled laboratory research applications.
