Profile: CPC Scientific, Inc. specializes in providing peptides. We are an ISO 9001:2000 certified company. Our biologically active peptides and their analogs are synthetically made and packed inside amber glass vials. Super majority of peptides are pre-made with minimum 95% purity and comes with HPLC, MS, AAA and peptide solubility information. Angiotensin converting enzyme inhibitor is a nonapeptide capable of inhibiting the conversion of angiotensin I to angiotensin II, in vitro and in vivo. Phospho peptides are essential tools to study phosphorylation by protein kinases in many eukaryotic cellular processes. Use of such peptides can determine how a cell responds to extracellular signals and how they produce intracellular responses. The specificity of the post-translational phosphorylation is critical in this kind of research.
