The unstimulated parent generation is indicated in blue. Objectives of the assay. Metabolic Proliferation Assays. If there is a way we can assist you, we are here to help - T cell activation by APCs, modelled in high throughput.Horizon’s Mixed Lymphocyte Reaction (MLR) Assay allows for the rapid identification of agents that modulate APC-mediated T cell activation. Human T lymphocytes stained with the CellTrace CFSE Cell Proliferation Kit and stimulated in culture for 5 days. CyQUANT Cell Proliferation Assays are ideal for high-throughput screening, are more sensitive than colorimetric-based assays, and are not radioactive. Assays that measure metabolic activity are suitable for analyzing proliferation, viability, and cytotoxicity. The conditions required to induce proliferation are described. DC are unique antigen presenting cells, and their ability to induce proliferation of T cells in a mixed leukocyte reaction (MLR) assay is commonly used for the evaluation of their function.

As the cells are stimulated to divide, they utilise the radio-labelled nucleotide in the culture media and incorporate it into their newly-synthesized DNA. The proliferation assay as described above provides information about the proliferation of a population of cells as a whole, rather than about individual cells. When we did observe IL-2 production, proliferation was observed in an associated manner, indicating soluble factor likely plays a role in proliferation. Horizon’s Mixed Lymphocyte Reaction (MLR) Assay allows for the rapid identification of agents that modulate APC-mediated T cell activation. For 2) A radio-labelled nucleotide is then addedto the culture media. also describe the assay in which CD4.CD25.T cells are co-cultured with conventional T cells in order to assess their suppressive function. The total radioactivity is measured, and compared against a control group of cells that did not receive the proliferation-inducing stimulus.The proliferation assay as described above provides information about the proliferation of a population of cells as a whole, rather than about individual cells. Additionally, the IncuCyte™ cell proliferation assay doesn’t require the use of any dyes or labels for confluence measurement, making the cells suitable for use in downstream assays. T cell proliferation, T cell exhaustion, Antigen-specific human CTL/Super-antigen T cell activation, Modelling immune cell synapse formation and maintenance, nTreg, iTreg and T cell differentiation are T-cell assays developed to observe priming and activation. 1) Cells in culture are given a specific stimulus. Not for use in diagnostic procedures. The amount of DNA in each cell remains constant for a given cell line or cell type, so assays based on DNA content—like Invitrogen CyQUANT Cell Proliferation Assays—can be used to provide an accurate and simple measure of cell number. This assay is relatively quick and inexpensive to perform, but does involve the use of radioisotopes, and a specialized machine to read the level of radioactivity present in the samples.

The most commonly used is 3H-thymidine. See your assay options with our Selection Guide.For Research Use Only. The in vitro proliferation assay can be used to determine whether or not cells are triggered to divide after exposure to a specific stimulus, or to assess differences between cell populations in their ability to divide in response to the same stimulus. This assay is relatively quick and inexpensive to perform, but does involve the use of radioisotopes, and a specialized machine to read the level of radioactivity present in the samples.An alternative experimental approach which provides more information about individual cells is to label cells in culture with a fluorescent marker, such as carboxyfluorescein succinamidyl ester ( This assay is relatively quick and inexpensive to perform, but does involve the use of radioisotopes, and a specialized machine to read the level of radioactivity present in the samples.An alternative experimental approach which provides more information about individual cells is to label cells in culture with a fluorescent marker, such as carboxyfluorescein succinamidyl ester ( To determine the mechanisms involved in DC-induced T cell activation in a primary MLR assay, a variety of diff … Assay your biologics or small molecules as single agents or in combination in high throughput.
