Solubility: Soluble in water to 5 mg/mL
Glucagon-like peptide-1 (GLP-1) is an incretin produced primarily in ileal L cells. GLP-1 secretion by these cells is dependent on the presence of nutrients in the lumen of the small intestine. GLP-1 promotes satiety and sustained GLP-1-receptor activation correlates with weight loss. The biologically active forms of GLP-1 are GLP-1 (7-37) and GLP-1 (7-36)NH2 (cat # 471-39 and 471-28, respectively) which are produced as a result of selective cleavage of proglucagon.
Each peptide comes complete with the following information:
a QC summary sheet
two reverse phase HPLC profiles to verify purity
mass spectrometry to verify molecular weight
amino acid analysis to verify composition
We use outside laboratories to provide the amino acid analysis and mass spectrometry. This third-party verification allows us to remain objective and has helped us achieve an excellent record of delivering top quality peptides since 1993.
