Webb1 maj 2024 · The most obvious advantage of DNA barcode-based MHC multimer technology is the possibility of screening for T-cell specificity using large libraries of epitopes with a single sample. The DNA barcode-based approach is also advantageous for detecting low avidity T cells because it provides enough signals with lower levels of …

MHC tetramers consist of four MHC molecules, a tetramerization agent and a fluorescently labeled protein (usually streptavidin). Streptavidins have also been generated with 6 or 12 binding sites for MHC.
