Competing interests The authors declare that they’ve no competing interests. Authors’ contributions AL and PDC, obtained the scFv optimized construct and performed IT expression and purification. MCa and SUF performed in vitro characterization of recombinant fusion proteins and cytotoxicity assays. LDL, IK, FG, EB and GT worked on the preparation of IT expressing constructs and on the purification of recombinant proteins. DJF, MCo, MSF, AC and RI contributed equally in designing experiments, analyzing and interpreting the information andThe Cathepsin S Storage & Stability stability of the anti-CD22 mAb and of the derived scFv was evaluated by incubation on the antibodies at 37 for the same occasions as in the internalization experiment (see beneath). The two antibodies have been diluted at concentrations of 0.5 gmL (mAb) and ten gmL (scFv) and incubated for up to 60 minutes at 37 within a water bath. At each and every time point the corresponding tube was transferred in ice and analysed by flow cytometry as described above.Della Cristina et al.
