Buy IGF-1 DES 1mg
BUY IGF-1 DES 1mg is a single, non-glycosylated, polypeptide. In vitro studies demonstrate that at equal doses DES (1-3) IGF is ten times more potent than IGF-1 at stimulating hypertrophy and proliferation in cultured cells. IGF-1 DES is a cleaved form of IGF-1 and contains amino acids 4-70. The IGF-1 DES, comes from the IGF-1 family of peptides that play important roles in mammalian growth and development. IGF1 mediates many of the growth-promoting effects of growth hormone and IGF-1 DES, although shorter, pacts an equal amount of physiological altering protein physical changes. Early studies showed that growth hormone did not directly stimulate the incorporation of sulfate into cartilage.
des(1-3)IGF-1 is a naturally occurring, endogenous protein, as well as drug, and truncated analogue of insulin-like growth factor 1 (IGF-1). des(1-3). IGF-1 lacks the first three amino acids at the N-terminus of IGF-1 (for a total of 67 amino acids, relative to the 70 of IGF-1). As a result of this difference, it has considerably reduced binding to the insulin-like growth factor-binding proteins (IGFBPs) and enhanced potency (about 10-fold in vivo) relative to IGF-1.
The amino acid sequence of des(1-3)IGF-1 is TLCGAELVDA LQFVCGDRGF YFNKPTGYGS SSRRAPQTGI VDECCFRSCD LRRLEMYCAP LKPAKSA.
