Total 174 AA, MW: 19.82 kDa (calculated). C-terminal His-tag, 7 extra AA (highlighted). E280 = 26150 M-1cm-1. The amino acid sequence of this product corresponds to the UniProtKB/Swiss-Prot entry P05090 (Human ApoD). Following modifications were made: Four amino acid exchanges were introduced at the surface of ApoD (Trp99His, Cys116Ser, Ile118Ser, Leu120Ser) to enhance the solubility of the recombinant protein and another three (Leu23Pro, Pro133Val, Asn134Ala) to facilitate its genetic manipulation (highlighted).
