Questions
What is IGF-1 LR3?
IGF-1 LR3 is a recombinant analog of insulin-like growth factor 1, comprising 83 amino acids with an arginine substitution at position 3 and a 13-residue N-terminal extension. Those modifications reduce binding to IGF binding proteins, which is why it is used as a long-acting reference analog in cell-culture and receptor-signalling studies.
What purity do you supply, and can I see the data?
Every batch is assayed at ≥99% purity by third-party HPLC with mass-spectrometry identity confirmation. The certificate of analysis for the exact lot you receive is available on request before or after purchase.
How should it be stored?
The lyophilised powder is stable at -20°C protected from light. Once reconstituted, laboratories typically store aliquots at -20°C and avoid repeated freeze-thaw cycles.
What are the terms of sale?
This material is sold strictly for in-vitro laboratory research. It is not a drug, dietary supplement or medical device, and it is not for human or veterinary use. Orders ship the same business day when placed before 2:00 PM ET.
