IGF-1 DES is a truncated IGF-1 variant studied for potent local IGF-receptor signalling in research models.
IGF-1 DES (DES(1-3) IGF-1) is a truncated variant of insulin-like growth factor 1, missing the first three N-terminal amino acids. This modification reduces binding to IGF-binding proteins, and it is studied in research for potentially potent, localized IGF-receptor signalling compared to full-length IGF-1.
IGF-1 research generally examines effects on cellular growth signalling, tissue-specific activity, and receptor interaction. The DES variant is investigated for its heightened local potency and reduced binding-protein interference, with data drawn primarily from in vitro and preclinical studies.
Studied for potent, localized IGF-receptor activation compared to full-length IGF-1 in research.
Investigated for lower IGF-binding-protein affinity, associated with increased local activity.
Examined for potential effects on cell-growth and proliferation signalling in experimental models.
Characterized through assays defining its IGF-receptor binding and potency profile.
Bring the vial (2 mg) and bacteriostatic water to room temperature.
Add bacteriostatic water slowly along the glass wall — the volume you add sets the concentration.
Swirl gently (do not shake) until fully clear, then refrigerate at 2–8 °C.
Studied together examining local IGF signalling alongside GHRH-driven growth-axis activity.
Explored in research combining local IGF-receptor activity with GH-secretagogue signalling.

IGF-1 DES is a truncated IGF-1 variant missing three N-terminal amino acids. This reduces binding-protein affinity and is studied for potent, localized IGF-receptor signalling in research.
The truncation lowers its affinity for IGF-binding proteins, so it is studied for heightened local potency and activity compared to full-length IGF-1 in research models.
It is studied in the context of cellular-growth signalling, tissue-specific IGF-receptor activity, and receptor interaction within in vitro and preclinical research models.
