Polyfunctional t cell assay
Web2 days ago · The multiplex-PCR assays profile the variations of the four T-cell receptor (TCR) or three B-cell receptor (BCR) chains present in the genomic DNA of immune samples. The assay results are obtained through next generation sequencing and provide important information on the abundance and diversity of T- or B-cell clonotypes in each sample. WebResults We found that inclusion of this domain in plasmid vaccines effectively trafficked antigens to endolysosomal compartments, resulting in enhanced major histocompatibility complex (MHC) class I and II presentation. Additionally, this augmented the expansion/activation of antigen-specific CD4+ and CD8+ T cells and also led to elevated …
