Human IL-15 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.
The purity of Human IL-15 is greater than 95% as determined by SEC-HPLC.
Human IL-2 R beta, His Tag captured on CM5 Chip via Anti-His Antibody can bind Human IL-15, No Tag with an affinity constant of 5.9nM as determined in SPR assay (Biacore T200).
Measured in a cell proliferation assay using MO7e human megakaryocytic leukemic cells. The ED50 for this effect is 1-2 ng/mL. The specific activity of recombinant human IL-15 is > 5 x 10^7 units/mg, which is calibrated against the human IL-15 reference standard (NIBSC code: 95/554) (QC Test).
Measured in a cell proliferation assay using MO7e human megakaryocytic leukemic cells. Bioactivity of three different batches of Human IL-15 shows very high batch-to-batch consistency.
