FIELD: biotechnology.
SUBSTANCE: invention relates to a tumour-specific peptide. Disclosed peptide is selected by a phage peptide library and has one of the following amino acid sequences: YTYDPWLIFPAN (SEQ ID NO 1) or FIPFDPMSMRWE (SEQ ID NO 2). Peptide has high specificity toward human breast cancer cells, including the ones of triple negative phenotype.
EFFECT: address chemotherapy of human breast cancer.
