Glucagon gene and the glucagon like peptide or GLP1 gene are peptide hormones, produced by alpha cells of the pancreas to raise the concentration of glucose in the blood as opposite of insulin, which lowers the glucose. Anti human glucagon and glp1 antibodies are used to study diabetes.Peptides short amino acid chains or epitopes or blocking antagonists. The shortest peptides are dipeptides, consisting of 2 amino acids joined by a single peptide bond, followed by tripeptides, tetra peptides, ... till polypeptides that are long, continuous, and unbranched synthetic peptide chains. These biological oligomers and polymers can be Solid-phase peptide synthesis (SPPS), or in continue produced for custom peptide synthesis projects. The High-efficiency solid phase peptide synthesis (HE-SPPS) is give very low production costs.
