WebThe below protocol provides the detailed description of MBP-scFv production in E. coli utilizing two expression systems: pMalc-TNN and pMalc-NHNN. Although the MBP tag does not disrupt the most of antibody activities, the MBP-TNN-scFv product can be cleaved by TEV protease in order to obtain untagged scFv. less WebThe choice of best candidates was performed by screening various other cell lines, using flow cytometry. The selected candidates were reformatted into Cys-ScFv or Cys-diabody by addition of cysteine, and cloned in mammalian expression vectors to obtain batches of small fragments that were further used in site-specific radiolabeling tests.
