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, the 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 the addition of an anti-CD28 antibody.

Depiction of capture effects observed in FluoroSpot

(1) IL-2 secreted by the activated T cell is captured by coated anti-IL-2 capture antibodies. (2) As a result, IL-2-stimulation of the T cell itself (autocrine stimulation) as well as nearby T cells (paracrine stimulation) is impaired, ultimately leading to (3) decreased IFN-γ secretion.

Co-stimulation with anti-CD28

Anti-CD28 mAb provides a co-stimulatory signal to antigen-specific responses by binding to CD28 on T cells. The addition of an anti-CD28 mAb to the cell culture enhances antigen-specific responses and can counteract capture effects. For example, the presence of IL-2 capture antibodies may result in reduced activation of T cells, as capturing of IL-2 decreases the amount of available IL-2 and thereby dampens the IL-2-mediated stimulation of T cells. The addition of anti-CD28 mAb restores IFN-γ responses (depicted in the below images). Further optimization may be necessary, depending on the cells and stimuli used. Too high concentrations of the anti-CD28 mAb may result in an elevation of non-specific cytokine secretion.

Overcoming capture effects using anti-CD28 anitbodies in FluoroSpot

(1) An anti-CD28 antibody can be added to provide a co-stimulatory signal that can restore (2) e.g. IFN-γ responses.

How to investigate capture effects

Our FluoroSpot Plus kits are evaluated for capture effects, and in studies of T cell responses we recommend co-stimulation with anti-CD28. With FluoroSpot Flex, it is possible to combine and build your own kit. For guidance look at our analyte combination table (above). Capture effects can be investigated by quantifying spot numbers in wells coated with single capture antibodies and compared to wells coated with a mixture of the capture antibodies. The compensatory effect of the anti-CD28 mAb may be assessed by comparing cells cultured with and without the anti-CD28 mAb.

The systems reactive with NHPs are either based on cross-reactive human kits or specifically developed monkey kits (NHP).

Cross-reactivity verification tests have been performed in ELISpot and/or ELISA by Mabtech and/or by others. Evaluations of assays with less solid evidence of cross-reactivity are shown as symbols within parentheses.

IL-17A

Analyte description

Interleukin 17A (IL-17A) is a potent proinflammatory cytokine produced by activated Th17 (T helper 17) cells and certain cells belonging to the innate immune system. In mice, IL-17 has also been shown to be produced by activated CD8 T cells and γδ T cells. Th17 cells play an important role in autoimmune diseases and protection against bacteria and fungi. IL-17A acts on a broad range of cell types to induce the expression of cytokines, chemokines, and metalloproteinases. As a result, secretion of IL-17A promotes inflammatory responses, which leads to the recruitment of neutrophils, enhancement of antibody production, and activation of T cells. Increased expression of IL-17A is seen in autoimmune diseases such as multiple sclerosis and rheumatoid arthritis. It is also associated with asthma, psoriasis, cancer, and transplant rejection.
