What is IGF-1 DES(1-3)?
IGF-1 DES, or DES(1-3)IGF-1, is a truncated 67-amino-acid variant that lacks the first three N-terminal residues of native IGF-1. That structural distinction changes IGFBP interactions and defines DES as a separate research material.
Controlled studies examine IGF-1 receptor binding, localized pathway activation, and short-window cellular-proliferation or differentiation endpoints. DES content is intentionally separated from LR3 so each page represents one molecular identity and research profile.
DES is not the long-acting LR3 analog. See also: IGF-1 LR3 for extended-window IGF signalling research →
IGF-1 DES COA lookup and verification
Each vial carries a batch identifier for checking the analytical documentation available for that material. The public lookup supports batch-level review, while the transparency page explains the identity, purity, and documentation framework. General verification information is not presented as a compound-specific result.

IGF-1 DES research questions
+What is IGF-1 DES?
IGF-1 DES, also written DES(1-3)IGF-1, is a 67-amino-acid variant of IGF-1 lacking the first three N-terminal residues. It is studied as a distinct, truncated IGF-1 reference material in controlled receptor and cellular-signalling models.
+How is IGF-1 DES different from IGF-1 LR3?
DES is a truncated 67-amino-acid variant studied for short-window and localized IGF signalling. LR3 is an extended 83-amino-acid analog engineered for reduced IGFBP binding and longer-duration signalling. The two names do not refer to the same compound.
+Which endpoints are measured in IGF-1 DES research?
Research commonly measures IGF-1 receptor binding, IGFBP interactions, localized pathway activation, and short-window cellular-proliferation or differentiation endpoints in controlled laboratory systems.
+Why is IGF-1 DES described as a truncated variant?
DES(1-3) lacks Gly-Pro-Glu, the first three amino acids of native IGF-1. That structural difference changes its interaction with IGF-binding proteins and is the defining identity feature examined in DES research.
+How can an IGF-1 DES batch be checked?
Use the batch identifier printed on the vial in the COA lookup. The transparency page explains the identity, purity, and documentation standards used for research materials and distinguishes available batch records from general verification information.
+What purity specification applies to IGF-1 DES?
The listed release specification is ≥99% purity. Researchers should confirm the result associated with received material using its batch identifier and the analytical documentation available for that batch.
+How should sealed IGF-1 DES be stored?
Keep the sealed lyophilized vial refrigerated, dry, and protected from light. Follow the storage information supplied with the batch for controlled laboratory handling and stability work.
