Figure 4From: A designer hyper interleukin 11 (H11) is a biologically active cytokineThe proliferation assay of B9 cells. B9 cells (1 × 104 cells per well) were tested for proliferation at various concentrations of (A) IL-11 and (B) H11. The medium without stimulator was used as the negative control. The proliferation of the cells was measured after 3 days using colorimetric assay based on MTT reagent.Back to article page
