Find out which analyte combinations we have evaluated in T cell FluoroSpot and which combinations are affected by capture effects or not. 

What is a capture effect?

When capture antibodies with different specificities are coated together, capture of one cytokine may affect the secretion of other cytokines. This is usually more pronounced when studying T cell responses with polyclonal stimuli compared to antigen-specific responses. Capture effects are seldom a problem and can often be counteracted by addition of an anti-CD28 antibody.

Analyte description

Tumor necrosis factor (TNF), also known as TNF-α, is produced by many different cell types, e.g., monocytes, macrophages, T cells, and B cells. Among the many effects of TNF-α are protection against bacterial infection, cell growth modulation, immune system regulation, and involvement in septic shock.
