VeriKine-HS Human Interleukin 15 ELISA Kit

• Measures endogenous human IL-15 at or near basal level with LLOQ of 0.51 pg/ml in serum, plasma, and cell culture media
• Detects both free and bound form of IL-15 (IL-15/IL-15R complex)
• Reproducible results with inter- and intra-CVs <10% in all tested matrices

PBL’s IL-15 ELISA measures both IL-15 alone and IL-15/IL15Rα complexes in Tissue Culture Media (TCM), and complex matrices such as serum and plasma. It can also quantitate IL-15 in healthy donor matrices. The standard in this assay is the IL-15/IL-15R heterodimer but because the antibodies used are specific for IL-15, the standard curve is calibrated to the IL-15 portion of the complex. Different forms of the IL-15 receptors (IL15-R) may couple to free IL-15 protein. This assay can detect both free IL-15 and bound IL-15/IL-15R.
