METHOD OF PREPARING OF RECOMBINANT PLASMIDS pC(Sp)S ENCODING CHIMERIC PROTEIN WITH SOMATOSTATIN SEQUENCE Russian patent published in 1995 - IPC

Abstract RU 2031121 C1

FIELD: genetic engineering. SUBSTANCE: recombinant plasmid DNA ДНК pC(Sp)nS is constructed which determines synthesis of chimeric protein containing part of chloramphenicol acetyltransferase, spacer (Sp)n-type and somatostatin-14. Spacer with values from 1 to 8 provides exhibition of somatostatin-14. Water insoluble enzymatically inactive chloramphenicol acetyltransferase without 10 terminal amino acids operates as carrier for somatostatin. Purified and renaturated chimeric protein synthesized in protease-defficient strain of bacterium Escherichia coli reacts with antibodies to somatostatin and induces synthesis of antistomatostatin antibodies at animal immunization. EFFECT: improved method of recombinant plasmid preparing. 5 cl, 2 tbl
