WebMay 1, 2005 · The FC-CTL assay was found to be sensitive enough to detect primary CTL responses. The usage of a pre-established GFP-expressing target cell line facilitated the procedure of the assay, and enabled a clear discrimination between target and effector cells. Time-course analyses demonstrated that PI-stained target cells were detected as … WebBackground: The most common assay used to detect natural killer (NK) and cytotoxic T-lymphocyte (CTL) ac-tivity is the 51Cr release assay. The numerous disadvan-tages of this method led us to evaluate cytotoxicity func-tions by flow cytometry. We described a flow cytometric assay to assess NK and CTL activity from different species.
WebIL-6 is a pleiotropic, alpha -helical, 22-28 kDa phosphorylated and variably glycosylated cytokine that plays important roles in the acute phase reaction, inflammation, hematopoiesis, bone metabolism, and cancer progression. Mature human IL-6 is 183 amino acids (aa) in length and shares 39% aa sequence identity with mouse and rat IL-6.
