About Growth & Recovery Research

Insulin-like growth factor (IGF) research focuses on the downstream effectors of the growth hormone axis. Our growth factor catalog includes IGF-1 LR3 (Long R3) with extended half-life and IGF-1 DES, a truncated variant with enhanced receptor binding for advanced research protocols.

Research Applications

Researchers study IGF-1 receptor signaling, enhanced receptor binding kinetics, extended half-life pharmacokinetics, and downstream growth factor pathways.

Key Compounds in This Category

Our growth factor catalog includes IGF-1 LR3 (extended half-life variant) and IGF-1 DES (enhanced receptor binding, five times more potent than standard IGF-1).

FAQ

Growth & Recovery Research — Frequently Asked Questions

What is IGF-1 LR3?

IGF-1 LR3 (Long R3) is a modified form of IGF-1 with extended half-life due to reduced binding to IGF-binding proteins. This allows for longer research protocols with fewer administrations.

Why is IGF-1 DES more potent?

IGF-1 DES is a truncated variant missing the first three N-terminal amino acids. This modification enhances receptor binding, making it approximately five times more potent than standard IGF-1 in receptor binding studies.
