Composition figures above are derived arithmetically from the published sequence for the unmodified free peptide. Salt forms (commonly trifluoroacetate or acetate), amidation, and other modifications shift the observed mass — always reconcile against the current lot certificate of analysis.
Volumes for a 1 mg vial of IGF-I (1-3) at common working concentrations. Add solvent slowly down the vial wall and swirl — do not vortex or shake.
Reference standards in the Growth Factors class are typically shipped as lyophilized powder and stored desiccated at −20 °C protected from light. Once reconstituted in bacteriostatic water or the assay-appropriate buffer, aliquot and store at −80 °C to minimize freeze–thaw cycles. Confirm handling requirements against your institutional biosafety and radiation protocols before use.
IGF-I (1-3) sits within the Growth Factors research class (CPC reference ILGF-003). Growth-factor peptides activate receptor tyrosine kinases (EGFR, FGFR, VEGFR, IGF-1R) and downstream RAS–MAPK and PI3K–AKT pathways that drive proliferation, migration, and survival. Investigators typically incorporate IGF-I (1-3) as a reference standard, tool ligand, or substrate in the assay contexts listed above. Phospho-ERK and phospho-AKT Western blots or AlphaLISA assays are the standard readouts.
IGF-I (1-3) (CPC catalog code ILGF-003) is a synthetic growth-factor / mitogen peptide in the growth factors category. It is provided as a lyophilized ~1 mg vial for in-vitro research use only.
Published and internal research programs use IGF-I (1-3) as a reference standard in growth factors workflows — for example, proliferation and brdu / edu assays and wound-healing and scratch-closure models. Human clinical evidence is not established.
No. IGF-I (1-3) is a research-grade reference peptide and is not approved by the FDA or any national regulator for human or veterinary therapeutic use. It is offered exclusively for in-vitro laboratory research and does not ship to the United States for consumer use.
In a growth factors workflow, IGF-I (1-3) is reconstituted in sterile buffer or DMSO (solubility-dependent) and applied in the researcher's chosen assay format. Phospho-ERK and phospho-AKT Western blots or AlphaLISA assays are the standard readouts.
Other reference standards in the same class — commonly cross-referenced during assay design and comparator selection.
