Human Bone Marrow Stromal Cell Antigen 2 (BST2) ELISA Kit

This quantitative immunoassay from Assay Genie is calibrated against human BST2, a 30-36 kDa type II transmembrane protein more commonly cited in the literature under the aliases tetherin, CD317, and HM1.24. BST2 is induced by type I interferons and is best known as a host restriction factor that physically tethers budding enveloped virions to the plasma membrane of infected cells, blocking their release. Because of this biology, the marker is monitored in immunology, virology, and oncology workflows studying interferon signaling, retroviral restriction, and the surface phenotype of malignant plasma cells in multiple myeloma research.

Reactivity is limited to human samples, and the kit supports BST2 measurement in tissue homogenates and cell lysates, using a colorimetric readout captured on a standard plate reader. Each kit ships as a complete reagent pack sized for 96 assays, supplied with standard curve materials and quality-control samples so that researchers can confirm run-to-run consistency across independent experiments. The product is labeled for research use only and supports in vitro studies of antiviral restriction, cytokine-stimulated cell line responses, and BST2 regulation in primary immune cells.
