Overview

IGF-1 LR3 — Long R3 IGF-1 analog

What is IGF-1 LR3? IGF-1 LR3 (Long R3 IGF-1) is an 83-residue analog of insulin-like growth factor 1. An arginine substitution and an N-terminal extension reduce its binding to IGF-binding proteins, which extends its activity relative to native IGF-1 — the reason it is a common tool in cellular-signalling and cell-culture research.

Research context The "long-acting" profile is precisely why researchers reach for the LR3 variant over native IGF-1 in many culture protocols. REPRIME supplies it in lyophilized 100 mcg and 1 mg vials; because IGF-1 LR3 is potent and used at low concentrations, accurate identity and purity data matter.

Quality and verification Every batch is HPLC-verified at ≥99% purity with a public COA, and each vial carries a unique REP-XXXX-XXXX-X code confirmable at /verify. For laboratory and research use only — not for human consumption.

Storage

FAQ

Frequently asked questions.

How does IGF-1 LR3 differ from native IGF-1?+

IGF-1 LR3 (Long R3) carries an arginine substitution and an N-terminal extension that reduce IGF-binding-protein binding, giving it a longer-acting profile used in cell-culture research.

What strength and purity is REPRIME's IGF-1 LR3?+

Lyophilized 100 mcg and 1 mg vials, HPLC-verified at ≥99% purity, each with a batch-specific COA on the product page.

How is this product shipped within Egypt?+

Orders ship in temperature-controlled packaging via insulated courier. Standard delivery is 1–3 business days from Cairo, within Egypt only.

How do I verify the product is authentic?+

Each vial's insert carries a unique code in the format REP-XXXX-XXXX-X. Enter it on the /verify page — the first scan stamps it verified; a later scan warns the code has already been used.
