IGF-DES Receptor Binding Specificity Competitive binding and receptor cross-linking experiments confirmed that both IGF-1 and des-(1-3)IGF-1 bind exclusively to the type 1 IGF receptor in L6 myoblasts, rat vascular smooth-muscle cells, and human lung fibroblasts with des-(1-3)IGF-1 demonstrating greater apparent potency in these assays, attributable to its low affinity for the competing 38 kDa IGFBP rather than differences in intrinsic receptor affinity
IGF-1 LR3's non-selective receptor activation affects muscle, adipose, cartilage, and connective tissue equally
Degraded GHK-Cu = less active peptide than the label suggests
