Maximize insights from SARS-CoV-2 T cell immune response

T cells are increasingly recognized for their role in SARS-CoV-2 infection and immunity, and the exploration of immune response markers during COVID-19 infection is becoming the next tool for researching potential improvements in patient management and vaccination guidance in the future.

To control the pandemic, we must first understand and control the infection. Exploration of immune response markers in SARS-CoV-2 infections is emerging as the next research tool as T cells are becoming increasingly recognized for their role in COVID-19 immunity.

Why T cells? Learn the answer from top scientists

Why T cells? Learn the answer from top scientists

In the fight against COVID-19, antibodies generated in response to a vaccine have taken center stage. What about the other arm of the adaptive immune response – T cells? T cells hunt and kill virus-infected cells and trigger cascades of other immune reactions, making them a critical part of the immune response.

Join three experts as they describe their latest research into SARS-CoV-2 T cell responses – and challenge us to look at T cells differently.

Easily assess cell-mediated immune response

QuantiFERON SARS-CoV-2 RUO solution is an original combination of blood collection tubes containing innovative specific peptides formulated to stimulate lymphocytes in heparinized whole blood involved in cell-mediated immunity. Plasma from the stimulated samples can then be used for detection of IFN-y using a simple ELISA.

  • Based on world-leading QuantiFERON IGRA technology
  • Customizable solution to fit your research needs
  • Unlock immune response potential for better research insights
