Receptor Grade IGF-1 LR3

Receptor Grade IGF-1 LR3 is an 83-amino acid IGF-1 analog (vs 70 in natural IGF-1) with extended N-terminus and arginine at position 3. These modifications reduce IGFBP binding while enhancing receptor affinity. Designed for cell culture studies with high purity. Research indicates applications in tissue anabolism, metabolism, and muscle studies.
