How to Reconstitute IGF-1: A Step-by-Step Guide
Reconstituting IGF-1 is not identical to reconstituting any other compound in this library. 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.
Overview
It does not go into plain water well. Dissolve it first in a mildly acidic liquid, then dilute into your working liquid, usually with a protein additive so it does not stick to the tube.
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.

Diluent selection for IGF-1
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.
Common reconstitution reference
A 1 mg vial in 1 mL yields 1 mg/mL. Dissolve first in dilute acetic acid, then dilute; aliquot for single use.
Open the IGF-1 calculatorMethod notes for this compound
- Dissolve first in dilute acetic acid, then dilute into the working buffer — never expect plain water to take it up fully.
- Use a carrier protein and low-bind labware to prevent adsorptive loss.
- Aliquot for single use; do not re-freeze reconstituted protein.
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.
