Human Interleukin-2 Soluble Receptor alpha ELISA Kit

Soluble IL-2 receptor alpha (sCD25) is a circulating biomarker widely used in immunology research, and this microplate-based immunoassay kit from Antibodies.com provides quantitative measurement of the human protein across three 192-well plates for a total of 576 determinations. The assay targets the shed extracellular domain of the IL-2Rα chain (CD25) and is configured for human samples from whole-blood-derived matrices and cell culture supernatant in studies of T-cell activation, regulatory T-cell function, and immune regulation.

Researchers employ sIL-2Rα quantification in investigations of sarcoidosis, hemophagocytic lymphohistiocytosis (HLH), adult-onset Still's disease, lymphoid malignancies, and transplant rejection, where elevated circulating levels serve as indicators of immune activation or disease activity. The kit is supplied with pre-coated microplates, detection antibodies, recombinant standards, and assay buffers required to generate a standard curve of analyte concentrations.

Reagents should be stored refrigerated upon receipt; reconstituted standards and working solutions may be aliquoted and frozen for extended stability through repeated freeze-thaw cycles. The product is intended for research use only and is not validated for diagnostic procedures. Each lot is quality-controlled to ensure consistent performance for longitudinal and multi-site studies.
