Vector for the expression of membrane receptors from mammals in unicellular organisms and method for the examination of ligand, which can be seen, these receptors

摘要

the invention relates to a vector replicable in cultures of organizations univellulaires, this vector containing a gene encoding a protein having the biological activity of eukaryotic membrane receptor and interacting with a regulatory protein, expressed as g protein, which set molecules of guanosine triphosphate (gtp).;the invention relates to cellular organisms transformed by such vectors described above.;it also refers to the ability of the detection methods in a molecule to behave as a ligand with a receptor and a procedure for studying the affinity of a receptor with a ligand, and a kit for the detection of ligand affinity towards a receiver.
