23 Jul DNA (deoxyribonucleic acid) aptamer GCA-5 capable of specifically identifying gastric cancer cells and application of DNA aptamer GCA-5
Abstract
The invention relates to the field of genetic engineering and in particular relates to a DNA (deoxyribonucleic acid) aptamer GCA-5 capable of specifically identifying gastric cancer cells and an application of the DNA aptamer GCA-5. A nucleotide sequence of the DNA aptamer GCA-5 is SEQIDNO.1, application of GCA-5 modified by a fluorescent substance or an enzyme substance in gastric cancer cell identification comprises auxiliary diagnosis, gastric cancer molecularly targeted diagnosis and gastric cancer biological guiding treatment which are applied to clinical gastric cancer tissue specimens, separation, purification and identification of gastric cancer cells in basic research as well as identification of gastric cancer tumour markers.
