| Description | ATR kinase substrate peptide (compound 45) is a potent and selective inhibitor of ATR (Ataxia Telangiectasia and Rad3 related) protein kinase (Ki=6 nM). ATR kinase substrate peptide inhibits ATR activity by competing with ATR kinase ATP-binding sites to block ATR mediated signaling. ATR kinase ATR kinase substrate peptide (compound 45) is a potent and selective inhibitor of ATR (Ataxia Telangiectasia and Rad3 related) protein kinase (Ki=6 nM). ATR kinase substrate peptide inhibits ATR activity by competing with ATR kinase ATP-binding sites to block ATR mediated signaling. ATR kinase substrate peptide can be used to study the role of ATR kinase in DNA damage response[1]... Read More | Amyloid β-Protein (3-42) TFA is a precursor of Pyr peptide.

Endomorphin 1 has antinociceptive properties[1][2][4] | Hexapeptide-11 is an anti-aging peptide that can protect fibroblasts from premature cell senescence mediated by oxidative stress. Hexapeptide-11 is also a potential stimulator of hyaluronic acid in keratinocytes, and can enhance skin barrier function by upregulating the expression of HAS2 and EGR3, Hexapeptide-11 is an anti-aging peptide that can protect fibroblasts from premature cell senescence mediated by oxidative stress. Hexapeptide-11 is also a potential stimulator of hyaluronic acid in keratinocytes, and can enhance skin barrier function by upregulating the expression of HAS2 and EGR3, and downregulating the expression of HYAL2. Hexapeptide-11 can also improve skin elasticity[1][2][3]...
