Provided in the present disclosure is a method for using a four-plasmid system to prepare modified immune effector cells. The method comprises: forming a lentivirus by using four plasmids within 293T cells, extracting and obtaining the lentivirus, then transfecting immune effector cells by using the lentivirus, and expressing a chimeric antigen receptor. Also provided in the present disclosure is a use of the immune effector cell obtained by using the described method and of a composition containing the immune effector cell.

Plasmid combination and application thereof in preparing modified immune cells

A chimeric antigen receptor, comprising an amino acid sequence shown in SEQ ID NO. 1. A nucleic acid encoding the chimeric antigen receptor, a vector comprising the nucleic acid, an immune effector cell comprising the chimeric antigen receptor, the nucleic acid molecule and/or the vector, a method for preparing the immune effector cell, a composition comprising the immune effector cell, and use of the chimeric antigen receptor.
