A TWO-COMPONENT VECTOR LIBRARY SYSTEM FOR RAPID ASSEMBLY AND DIVERSIFICATION OF FULL-LENGTH T-CELL RECEPTOR OPEN READING FRAMES

摘要

A combined system comprising two separate components, wherein a first component is a vector carrying variable and constant (V-C) T-cell receptor (TCR) gene segments, and a second component is a vector carrying joining (J) TCR gene segments. The combined system may be modified so that said first component is a modified V-C entry vector encoding a first TCR chain, the system further comprises a fourth and a fifth component, wherein the fourth component comprises a Bidirectional Terminator (BiT) donor vector, and the fifth component comprises a modified V-C entry vector encoding a second TCR chain complimentary to said first TCR chain.
