What Does IGF-1 Dissolve In? Solvents Explained
Solubility behaviour is where compounds in this library differ most sharply from one another. For IGF-1, the determining factors are structural: 70-residue single-chain protein (native igf-1), three disulfide bonds.
Overview
Poorly soluble at neutral acidity — undissolved bits in plain water are expected, not a bad vial. Acidic liquid first is the fix.
What IGF-1 actually is
The natural growth factor the body produces after growth hormone acts — a folded protein, not a simple peptide, studied for muscle and tissue signalling. This is the native form, different from the longer-acting LR3 version.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

How IGF-1 behaves in solution
As a folded protein, IGF-1 dissolves poorly at neutral pH and is conventionally taken up first in a mildly acidic solvent, then diluted into the working buffer. A carrier protein is commonly used to limit adsorptive loss. Direct dissolution in plain water or PBS can leave incomplete dissolution — expected chemistry, not a defective vial.
Worked at low concentrations; a carrier protein matters more than the ceiling.

Structural basis
IGF-1 is 70-residue single-chain protein (native igf-1), three disulfide bonds. IGF-1 is the native insulin-like growth factor — a folded 70-amino-acid protein stabilised by three internal disulfide bonds. It is the downstream messenger produced after growth hormone acts, and it is handled as a protein rather than a short peptide. This is the native sequence, distinct from the long-acting LR3 analogue.
What IGF-1 is studied for
Studied as the native ligand for the IGF-1 receptor and its downstream proliferation and survival pathways.
Examined in muscle research models for its role in satellite-cell behaviour and anabolic signalling.
Compared with IGF-1 LR3, whose reduced binding-protein affinity gives a longer active window — a contrast studied directly in the literature.
