METHOD AND SET FOR DETECTING GENE ENCODING MEMBRANE-BOUND PROTEIN, VECTOR (VARIANTS)

FIELD: genetic engineering, molecular biology. ^ SUBSTANCE: invention proposes a method for detecting genes encoding membrane-bound transmembrane proteins. Method involves expression of the nucleic acid chimeric sequence in the cell-host consisting of DNA fragment encoding secreting protein that is able to bind antigen and DNA fragment to be tested; interaction of cells expressing the fused protein with antigen; selection of cells on surface of that indicated antigen is bound; isolation of recombinant vector containing in selected cells of DNA fragment to be tested and, if necessary, determination of its sequence. Also, invention proposes the developed vector constructions and comprising their sets designated for realization of the proposed method. Invention provides significant simplifying the screening process of libraries and cloning genes encoding transmembrane proteins. Invention can be used for detecting and preparing genes encoding any membrane-bound proteins used in different branches of science and practice. ^ EFFECT: improved isolating method, valuable biological properties of protein. ^ 27 cl, 7 dwg, 1 tbl, 8 ex
