The invention relates to a histidine-containing oligopeptide comprising an amino acid sequence selected from the group consisting of: HHHNSWDHDINR (SEQ. ID No. 1), HTNIHQDQHNHFHR (SEQ. ID No. 2), HAMLDRAHDHGTR (SEQ. ID No. 3), SLHEHHSGDNLR (SEQ. ID No. 4), THY-NAVHSHNTLQ (SEQ. ID No. 5), DIHHWTDHLQSSTH (SEQ. ID No. 6), and LYNHYSHTAHVNHL (SEQ. ID No. 7), a polypeptide which is a fusion protein comprising a protein molecule of interest fused at its amino terminus or carboxy terminus to said oligopeptide, a polypeptide obtainable by cultivating a host cell comprising a polynucleotide construct encoding said polypeptide in an appropriate growth medium under conditions allowing expression of said polypeptide and recovering said polypeptide from the culture medium, a polynucleotide construct encoding said polypeptide, a host cell comprising said polynucleotide construct and a method for producing said polypeptide.
