About IGF-1 LR3 Peptide UK

IGF-1 LR3 is a modified analogue of insulin-like growth factor 1 containing an extended N-terminus and an arginine substitution. These changes reduce binding to several IGF-binding proteins and create a research profile distinct from native IGF-1.

IGF-1 LR3 Research

IGF-1 LR3 is used in experimental work on IGF-1 receptor signalling, PI3K-AKT and MAPK pathways, cell growth, differentiation, protein-synthesis signalling and nutrient metabolism. The analogue’s reduced interaction with binding proteins (Learn more) makes it useful for studying IGF-receptor biology under conditions that differ from endogenous IGF-1 regulation, alongside related growth-factor research such as [Tesamorelin] and [AOD-9604].

IGF-1 LR3 Frequently Asked Questions

What is IGF-1 LR3?
IGF-1 LR3 is a modified long-acting research analogue of insulin-like growth factor 1, supplied by Crown Peptides at 1mg strength.

What does LR3 mean?
The name refers to the extended analogue containing an arginine substitution at position 3 together with an additional N-terminal sequence.

What is IGF-1 LR3 researched for?
Research includes IGF-1 receptor signalling, cell growth, differentiation, protein synthesis and nutrient-related signalling.

Why do researchers distinguish IGF-1 LR3 from native IGF-1?
Its structural modifications alter interactions with IGF-binding proteins, so its experimental behaviour differs from endogenous IGF-1.

How should IGF-1 LR3 identity be confirmed?
Because it is a larger peptide analogue, the batch-specific analytical documentation should be used to confirm exact sequence identity, molecular mass and purity.
