CARRIER FOR TARGETED DELIVERY OF NUCLEIC ACIDS TO CELLS EXPRESSING RECEPTOR CXCR4

摘要

FIELD: biotechnology.;SUBSTANCE: carrier is proposed for targeted delivery of nucleic acids to cells expressing the receptor CXCR4, which consists of a sequence-ligand to the receptor CXCR4 with the amino acid sequence KPVSLSYRSPSRFFESH, the linker part of two molecules of ε-aminohexanoic acid linking the sequence-ligand to the sequence for compaction of nucleic acids, the sequence providing compaction of nucleic acids and the complex output from endosomes CHRRRRRRHC.;EFFECT: invention can be used for targeted delivery of genetic structures into cells with the receptor CXCR4 on the surfaces, such as malignant tumour and stem cells, in order to correct genetic defects, influence on processes of implementation of the genetic information and prevention of diseases.;3 cl, 7 dwg, 4 ex
