Used in biomedical research to quantify levels of SDF-1a (CXCL12), a chemokine involved in cell migration, immune response, and tissue repair. The ELISA kit enables detection of SDF-1a in serum, plasma, cell culture supernatants, and tissue extracts. Commonly applied in studies related to inflammation, cancer metastasis, stem cell homing, and cardiovascular diseases. Helps researchers evaluate SDF-1a expression under various experimental conditions, supporting drug development and mechanistic studies in immunology and regenerative medicine.
