Human Leukosialin (SPN) ELISA Kit

Manufactured by Assay Genie, this sandwich-format ELISA kit enables the quantitative measurement of leukosialin, a cell surface glycoprotein also known as SPN or CD43, in human samples. The protein plays a key role in cell adhesion, signaling, and immune response regulation, and its abnormal expression has been associated with cancer, inflammatory disorders, and autoimmune conditions, making it a valuable biomarker for research in immunology, oncology, and cell biology.

The assay is reactive with human samples, including serum, plasma, tissue homogenates, cell culture supernates, and other biological fluids, and detects both natural and recombinant human leukosialin. It offers a detection range of 0.156-10 ng/mL with a sensitivity of 0.053 ng/mL, an intra-assay CV of 6.9%, and an inter-assay CV of 11.8%. The procedure uses a pre-coated plate with TMB substrate, with absorbance measured at 450 nm. Kit components should be stored at 2-8°C for 12 months, and the product is intended for research use only.
