CRP and cancer: In this study, we have assessed the potential of KT2440 for the soluble production of different recombinant scFvs namely, the model murine anti-hen egg-white lysozyme scFv, D1.3 [11,16-19], and two phage display-selected human scFvs: TOB5-D4 [[11], Al-Halabi et al. in preparation], directed against C-reactive protein (CRP) [20], an inflammation indicator in human blood, and HT186-D11 [21], directed against mucin1 (MUC1), a diagnostic marker and potential therapeutic target of cancer [22,23].
