FIELD: biotechnologies.SUBSTANCE: peptide derivatives of exendin -3 (1-39) are described, having activity of glucagon-like peptides (GLP-1), modified near C-end with amine and capable of binding with their N-end to GLP-1-receptors. Application of peptide derivatives of exendin-3 is disclosed for production of an agent for diagnostics and therapy of diseases, where expression of GLP-1 receptors is important, to define density of insulin-producing cells in a tissue, in order to define expression of GLP-1 -receptors or their density.EFFECT: invention may be used to produce an agent for diagnostics and therapy of diseases, where expression of GLP-1 receptors is important.21 cl |
