The FluoroSpot assay is a modification of the ELISPOT assay. ELISPOT usually measures the cellular secretion of one cytokine in each well by the use of an enzyme labeled anti cytokine antibody. FluoroSpot measures the secretion of several cytokines in each well by the use of fluorescent anti cytokine antibodies. The method can be applied to essentially any system where one wants to investigate dual or triple protein secretion at the single cell level or where one wants to benefit from the fact that several cytokines can be assessed simultaneously in the same well, for example when there is a limited supply of cells. The FluoroSpot method is especially attractive in situations where the producing cells represent only a small fraction of the cell population, e.g. when studying polyfunctional T cells. The sensitivity of the FluoroSpot assay is similar to that of the traditional ELISPOT and it has been used to analyze both polyclonal and antigen specific immune responses in ex vivo stimulated peripheral T cells. Like the ELISPOT , the FluoroSpot assay is simple to perform, sensitive and suitable for individual tests as well as for large scale screening. Principle and Procedure Image Fluorospotprincipfinal.jpg thumb Figure 1. Principle of FluoroSpot detection of cells secreting two cytokines IFN and IL 2 . The principle and procedure for FluoroSpot see Fig 1 is similar to ELISPOT . However, to detect cells secreting e.g. two different cytokines, a mixture of two capture antibodies, specific for the two cytokines, is coated in each well of a 96 well plate. Further on, after cellular stimulation, incubation and subsequent washing away of the cells, a mixture of two anti cytokine antibodies is added to detect the secreted cytokines. To enable a separate detection of the two secreted ..., 2003. Boulet S, et al. A dual color ELISPOT method for the simultaneous detection of IL 2 and IFN ...

Interferon release assays IGRA are medical tests used in the diagnosis of some infectious diseases, especially tuberculosis . Interferon release assays rely on the fact that T lymphocytes will release interferon when exposed to specific antigens. These tests are mostly developed for the field of tuberculosis diagnosis , but in theory, may be used in the diagnosis of other diseases which rely on cell mediated immunity, e.g. cytomegalovirus and leishmaniasis . For example, in patients with cutaneous adverse drug reaction s, challenge of peripheral blood lymphocytes with the drug causing the reaction produced a positive test result for half of the drugs tested. ref cite web url http www.sciencedirect.com science? ob ArticleURL& udi B6WM8 4FC365G J& user 10& coverDate 02 2F28 2F2005& rdoc 1& fmt & orig search& sort d&view c& acct C000050221& version 1& urlVersion 0& userid 10&md5 e44c54a7f2706a47c104ffae7bbe376f title Clinical implications of in vitro drug induced interferon gamma release from peripheral blood lymphocytes in cutaneous adverse drug reactions ref There are currently two interferon release assays available for the diagnosis of tuberculosis QuantiFERON TB Gold licensed in US, Europe and Japan and T SPOT.TB , a form of ELISPOT licensed in Europe .

T SPOT. TB is a type of ELISPOT assay used for tuberculosis diagnosis . It is available in most European countries, the United States as well as various other territories. It was developed by researchers at the University of Oxford in England. ref http www.isis innovation.com news news oxfordimmunotec nov02.html ref It counts the number of effector T cells , white blood cell s that produce gamma interferon , in a sample of blood. This gives an overall measurement of the antigen load on the immune system, which can reveal the presence of subclinical disease. Because this does not rely on production of a reliable antibody response or recoverable pathogen , the technique can be used to detect conditions such as latent tuberculosis . ref Cite web url http www.oxfordimmunotec.com How It Works International title How T SPOT.TB Works ref This technique is especially useful because it is much faster results within 24 hours than the previous methods and more accurate the previous skin test would result in positive if a person doesn t have TB but has had the vaccine before or if has come into contact with the mycobacterium before .

orphan date October 2009 The Streptamer technology allows the reversible isolation and staining of antigen specific T cells . This technology combines a current T cell isolation method with the Strep tag technology. In princible, the T cells are separated by establishing a specific interaction between the T cell of interest and a molecule that is conjugated to a marker, which enables the isolation. The reversibility of this interaction and the fact that it can be performed at low temperatures is the reason for the successful isolation and characterization of functional T cells. Because T cells remain phenotypically and functionally indistinguishable from untreated cells, this method may offer new strategies in clinical and basic T cell research. ref Knabel, M., Franz, T.J., Schiemann, M., Wulf, A., Villmow, B., Schmidt., B., Bernhard, H., Wagner, H. and Busch, D. 2002 Reversible MHC multimer staining for functional isolation of T cell populations and effective adoptive transfer.
