Scfv mammalian expression
WebBatch conversion of scFv to full-length human IgG for SiPF. We used a 2-step strategy for the scFv batch conversion. In step 1, the (G 4 S) 3 scFv linker was replaced by a DNA segment coding for the hinge and constant domains for (HC) and the promoter and signal sequence for (LC). This was achieved by PCR of the phagemid library using 3′ primers annealing to … WebTGEX-SCblue is a mammalian expression vector especially designed for the conversion of scFv phage clones into scFv-Fc fusion proteins that can be quickly expressed by transient expression into HEK293 cells with yields between 10 mg/l and 100 mg/l or more in just a few days. The bivalent Fc fusions are secreted in the supernatant and in most ...
