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. WebThe mouse T-cell line CTLL-2 is known to be dependent on interleukin-2 (IL-2) for both growth and viability. ... Although only very limited proliferation was observed during the incubation as assessed by 3H-thymidine incorporation, the viability of the CTLL-2 cells on the immobilized IL-2 matrix was preserved. Cells incubated on the immobilized ...

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. WebFeb 16, 2024 · CCK-8 assay TGF-β could inhibit the IL-2 dependent proliferation of CTLL-2 and HT-2. We performed CCK-8 assays to measure the capability of YM101 antagonizing the effect of TGF-β. CTLL-2 and HT-2 cells (1 × 10 3 per well) were seeded in 96-well plates (3599, Corning). Then, TGF-β1 and antibodies (10 5 pM) were added into plates. how do i know if my phone has been infected
