Reliable analysis of rare virus-specific T cells 

T cells play a pivotal role in fighting viral infections and generating long-term protective immunity after infection and vaccination. 

Assessment of specificity, phenotype, and cytokine secretion of rare virus-reactive T cells can provide essential information on infection progression, prior infections or vaccination efficacy.

Protocol

Rapid antigen-specific T cell enrichment (Rapid ARTE)

Combine magnetic cell enrichment and multiparameter flow cytometry analysis for direct ex vivo characterization of human antigen-specific CD154+CD4+ T cells.

Safe flow sorting of antigen- and virus-specific T cells

When working with contaminated or infectious material, operator safety is of the utmost importance. Our MACSQuant® Tyto® Cell Sorter allows gentle and sterile sorting of even the rarest virus-specific T cells in a closed aerosol-free cartridge system.
