About IGF-1 LR3
IGF-1 LR3 is a recombinant analogue of IGF-1: a single-chain polypeptide of eighty-three amino acid residues. Recombinant means the chain is produced by expression in a host organism and then purified, rather than assembled residue by residue through solid-phase synthesis like most compounds in this catalogue. Its name refers to an arginine at position 3 and a lengthened N-terminus, and at eighty-three residues it sits at the boundary between peptides and small proteins.
Polypeptides of this length are characterised by reversed-phase HPLC and by electrospray mass spectrometry, in which the molecule appears as a series of multiply charged ions deconvoluted to a single neutral mass; SDS-PAGE is often used alongside to show apparent molecular mass. Each presentation is supplied as a lyophilised powder in a sealed vial.

Questions about IGF-1 LR3
IGF-1 LR3 is a recombinant analogue of insulin-like growth factor 1, a single-chain polypeptide of eighty-three amino acid residues. It is supplied in a sealed vial as a white to off-white lyophilised powder, in a 1 mg presentation.
Yes. Long R3 IGF-1 is the longer form of the same name: a recombinant single-chain polypeptide of eighty-three residues with an arginine at position 3 and a lengthened N-terminus.
L stands for the lengthened N-terminus and R3 for the arginine at position 3. Together they describe how the eighty-three-residue chain is built.
Eighty-three, in one continuous chain. At that length it sits at the boundary between peptides and small proteins, so it is analysed with the methods used for both.
Because a chain of eighty-three residues suits expression in a host organism followed by purification, rather than built residue by residue through solid-phase synthesis like the shorter peptides in the catalogue.
Order IGF-1 LR3 directly from British Peptide Labs, a UK-registered company. It is supplied in a sealed 1 mg vial at £85.00 (£85.00 per mg). Every vial is ≥99% purity (HPLC), with independent third-party testing by PeptideVerify. Orders placed before 3pm Mon–Sat leave the same day by Royal Mail Tracked 24 for next-day tracked delivery.
IGF-1 LR3 comes in one sealed vial: 1 mg at £85.00 (£85.00 per mg). Delivery is free on every order.
IGF-1 LR3 is catalogued in the GHRH, GHS-R & IGF-1 Analogues research area, where compounds are grouped by molecular class. The research area page lists each of them with its identifiers.
GHRH, GHS-R & IGF-1 Analogues research areaIGF-1 LR3 has independent third-party testing by PeptideVerify: reversed-phase HPLC measures purity, at ≥99% (HPLC), and LC-MS confirms identity against the expected mass.
