Analysis of the bioengineered DOXMS2 silk. a The amino acid sequence of the DOXMS2 construct. The protein consists of 15 repeats of a monomeric unit derived from MaSp2 silk from the spider N. clavipes and a peptide DOX with affinity towards doxorubicin (indicated in italics). b SDS-PAGE analysis of purified DOXMS2. 1 Precision Plus Protein â„¢ Kaleidoscope â„¢ molecular weight marker; 2 DOXMS2 silk
