Used to measure SDF-1α (stromal cell-derived factor-1 alpha) levels in human biological samples such as serum, plasma, or cell culture supernatants. This assay is commonly applied in research related to stem cell mobilization, tissue regeneration, and immune cell trafficking. It supports studies in cancer biology, particularly tumor metastasis, as SDF-1α plays a role in directing cell migration through interaction with CXCR4 receptors. Also utilized in cardiovascular research to assess involvement in angiogenesis and repair after injury. Provides a reliable, sensitive, and quantitative method for detecting SDF-1α in clinical and experimental settings.
