IGF-1 LR3 UK — buying guide
What to check before you buy IGF-1 LR3 in the UK: the Long-R3 IGF-1 analogue, one of the larger molecules in the catalogue, verified per batch.
What is IGF-1 LR3?
IGF-1 LR3, also called Long-R3 IGF-1, is an 83-amino-acid analogue of insulin-like growth factor 1. It differs from native IGF-1 by an arginine substitution at position 3 and a 13-residue N-terminal peptide extension. It carries CAS number 946870-92-4 and a molecular weight of approximately 9117.6.
In the laboratory IGF-1 LR3 is used as a growth-factor reference material in cell-culture and preclinical research. Sova supplies it as a 1mg research vial for controlled laboratory investigation — not for human or veterinary use, and with no claim of any effect in people.
Before you buy
How to verify IGF-1 LR3 before you buy
IGF-1 LR3 is one of the largest molecules in the catalogue (~9117.6 Da), so identity confirmation by mass spectrometry against the batch matters as much as the purity figure.
Every Sova IGF-1 LR3 vial ships with a batch-linked Certificate of Analysis. Before you buy, confirm the CoA references the batch on the vial, that identity is confirmed by ESI mass spectrometry against the expected ~9117.6 Da, and that purity is measured by reverse-phase HPLC. Enter the batch at /verify to pull the certificate.
Why buy IGF-1 LR3 from Sova
- ✓HPLC (purity) + ESI mass spectrometry (identity) on every batch — no exceptions.
- ✓A batch-linked Certificate of Analysis you can verify from the code on the vial.
- ✓UK stock, same-day dispatch before 3pm, cold-chain packaged and tracked.
- ✓Supplied strictly for laboratory research use only.
