IGF-1 LR3 1mg 3ml Research Peptide

IGF-1 LR3 1mg 3ml Research Peptides in UK (Insulin-Like Growth Factor-1 Long R3)

IGF-1 LR3 is a recombinant analog of human Insulin-Like Growth Factor 1 (IGF-1), engineered with an N-terminal 13-amino-acid extension and a glutamic acid substitution at position 3 (Arg→Glu). This modification substantially reduces its affinity for IGF binding proteins (IGFBPs), resulting in a significantly longer half-life compared to native IGF-1. It binds to the IGF-1 receptor (IGF1R) and activates downstream PI3K/Akt and MAPK/ERK signalling cascades.
