Patent ID: 12012610

Abstract:
The present invention relates to A multicomponent system wherein a first component is an engineered antigen-presenting cell (eAPC) designated component A and a second component is a genetic donor vector, designated component C, for delivery of one or more ORFs encoding an analyte antigen-presenting complex (aAPX) and/or an analyte antigenic molecule (aAM), wherein component A a. Lacks endogenous surface expression of at least one family of aAPX and/or aAM and b. Contains at least two genomic receiver GO sites, designated component B and component D, each for integration of at least one ORF encoding at least one aAPX and/or aAM, and component C is matched to a component B, and wherein component C is designed to deliver c. A single ORF encoding at least one aAPX and/or aAM or d. Two or more ORF encoding at least one aAPX and/or aAM, wherein the genomic receiver sites B and D are synthetic constructs designed for re-combinase mediated exchange (RMCE).
