Human IL-15RA/IL-15 R alpha ELISA Kit

This sandwich ELISA kit from Assay Genie is intended for the quantitative detection of human IL-15RA (interleukin-15 receptor subunit alpha; CD215) in serum, plasma, cell culture supernatant, cell or tissue lysate, and other liquid samples. The assay uses a double-antibody sandwich format with colorimetric readout measured at 450 nm, and the unopened kit is stored at 2-8°C for 12 months. Reported performance figures include a sensitivity of 4.688 pg/mL and a standard curve range of 7.813-500 pg/mL. Validation data show recovery ranges of 88-102% in serum, 85-105% in EDTA plasma, and 86-97% in heparin plasma, with linearity of 87-98% (serum), 85-99% (EDTA plasma) and 82-92% (heparin plasma) at a 1:2 dilution. The target is a high-affinity receptor for interleukin-15 involved in the activation and proliferation of natural killer cells and CD8+ T cells, making this kit relevant to cell biology and immunology research, including studies of autoimmune and inflammatory disease.
