IGF-1 LR3 | Long-Acting Analogue for Research

We offer high-purity, recombinant IGF-1 LR3 (Insulin-like Growth Factor-I Long Arginine 3), a potent, long-acting analogue of human IGF-1. This protein is supplied as a lyophilized powder to ensure maximum stability and bioactivity for use in a wide range of in-vitro research applications.

IGF-1 LR3 is an 83-amino acid peptide that has been modified to include an N-terminal 13-amino acid extension and a substitution of Arginine for Glutamic Acid at position 3. These alterations significantly reduce its affinity for Insulin-like Growth Factor Binding Proteins (IGFBPs). This characteristic makes IGF-1 LR3 an invaluable tool for scientists studying the IGF-1 receptor signaling pathway, cellular proliferation, and differentiation in a controlled laboratory environment, with a greater and more consistent bioavailability compared to standard IGF-1.

Storage and Handling

For optimal integrity, it is recommended to store lyophilized IGF-1 LR3 in a freezer at -20°C. Once reconstituted, the protein solution should be stored in a refrigerator at 2-8°C for short-term use. For long-term storage, it is best to aliquot the reconstituted solution and store it in a freezer at -20°C or -80°C. Avoid repeated freeze-thaw cycles.
