Long-Arg3 insulin-like growth factor analogue

IGF-1 LR3 is a modified analogue of insulin-like growth factor 1, studied downstream of the growth-hormone axis for its extended activity and reduced binding-protein affinity relative to native IGF-1.

Research Overview

IGF-1 LR3 binds the IGF-1 receptor with reduced affinity for IGF-binding proteins, extending its activity window in research models.

Because responses in this class of research are dose- and purity-sensitive, impurity shows up directly as noise in the data. ONE% supplies IGF-1 LR3 lyophilised, batch-verified, so the signal being measured stays clean from study to study.

Mechanism In Brief

IGF-1 LR3 binds the IGF-1 receptor with reduced affinity for IGF-binding proteins, extending its activity window in research models.

Handling & Reconstitution

Every ONE% compound ships as a lyophilised powder for stability in transit. Reconstitute with bacteriostatic water to the concentration your protocol requires, store at 2–8°C protected from light, and use within your laboratory’s validated window. Each vial is batch-referenced to its Janoshik Certificate of Analysis, available on request.

Important

For research and laboratory use only. IGF-1 LR3 is supplied strictly as premium-grade research material with a batch Certificate of Analysis. It is not a drug, supplement, food, or cosmetic, and is not intended for human or veterinary use, diagnosis, treatment, or the prevention of any condition. All statements describe published research directions only.

Good To Know

Common Questions.

It ships as a lyophilised (freeze-dried) powder. In the lab it's reconstituted with bacteriostatic water to the concentration your protocol requires. Kept sealed, cold and dark, it stays stable until you need it.

Sealed at 2–8°C, protected from light. As a lyophilised powder it's stable in transit; once reconstituted, follow your laboratory's validated window.

No, every compound ships as a lyophilised vial and is reconstituted in the lab. The ONE% Pen is a separate reusable instrument for laboratories that want repeatable, graduated delivery instead of drawing by syringe each time. Buy it once; it is not tied to any one compound.

Every vial carries a batch code. Enter it on our batch verification page to pull up that batch’s Certificate of Analysis, or ask us for the certificate before you order, we would rather you check than take our word for it.

It is the target every batch of IGF-1 LR3 is held to, measured by HPLC at Janoshik and reported on the COA as a percentage of the total peptide content. Identity is confirmed separately by mass spectrometry. A purity figure without a named method and a batch reference behind it is marketing, not data.
