Design Notes

Choosing nanobody as the ideal antibody in our project aims to avoid the disadvantage of traditional antibodies, among which the most difficult is the large sequence amount of these antibodies that may influence the transfection or the expression of the part. Linking the recombinate scFv of erbB3 and the hIgG1-Fc makes a promising recombinant antibody that is both recognizable by trim21 and small enough to be inserted into the plasmid. P2A in our design aims to achieve the automatic cleavage of two peptides , offering a convenient way to express two proteins only with one promoter. 3XGS is the improvement we made this year, based on a 2XGS linker(BBa_K1486004). Besides the increased length, we made changes on the sequence of the middle GGGGS, so that the 3XGS could be more flexible and more specific in PCR and other aspects.
