CAR_library
As we have mentioned in BBa_K4421003, we designed a scFv library with 10 individual colonies. This composite part is formed of 10 kinds of unique CAR constructs based on BBa_K4421003.
Structure of CAR_library
Our design is based on second-generation CAR, consisting of 1)endodomain: CD28 and CD3ζ 2)transmembrane domain: CD8TM
3)ectodomain: CD8 hinge and the scFv library. The unique point of our design is the scFv library, theoretically composed of all
kinds of scFvs which can be genetated by human bodies. In our cellular experiment, we selected 10 scFvs to form a small library, which is detailed in BBa_K4421003.
Theoretical base
According to the clonal selection theory, a healthy adult with a normal immune system could produce a very large number of antibodies against all antigens beforehand, including heterogeneous tumor antigens. So we can utilize these antibodies to form a antibody or scFv library which aims for almost all antigens.
Special Note
Since our part BBa_K4421003 is a general concept without a specific sequence, we use BBa_K4421011 cetuximab scfv to serve as a placeholder. In other words, the place where BBa_K4421011 at can be replaced by any other scFv to form diverse CAR constructs.
