WebCTLL-2 cells were seeded in a 96-well plate and treated with varying concentrations of Human Recombinant IL-2. Cell proliferation was measured using a colorimetric assay. In the graph below, the specific activity was determined to be ≥ 5 x … Webinterleukin-15, antagonist, peptide, serum, CTLL-2 cell line, proliferation assay. ABSTRACT Dysregulated expression of Interleukin (IL)-15 has been associated to several autoimmune and inflammatory diseases. In this sense, some agents that inhibit IL-15 activity have been developed as possible drugs to treat these pathologies.
WebCellGenix® GMP rh IL-2 has an activity of 8 – 32 × 106 IU/mg. The activity of GMP rh IL-2 was measured in a cell proliferation assay using the IL-2-dependent cell line CTLL-2. It was calibrated against Proleukin®. You can find the batch specific activity on the certificate of analysis (CoA). WebThe bioactivity of the superagonist was characterized by CTLL-2 cells proliferation assay in vitro, showing its capability of stimulating the expansion of memory CD8 + T cells (cluster of differentiation) in mouse spleen.
WebWhen maintained in continuous culture, however, the overall sensitivity of this cell line is highly variable. To overcome this problem, large batches of CTLL-2 were grown, frozen and tested for their ability to detect low levels of IL-2 (0.01 IU) in dose response assays. Batches meeting this criterion were stored in liquid nitrogen until required.
