Used in biomedical research to detect and quantify S100A4 protein levels in biological samples such as serum, plasma, and tissue homogenates. This kit is widely applied in cancer research, particularly in studies related to tumor metastasis, as S100A4 is associated with cell motility, invasion, and poor prognosis in various cancers. It is also used in inflammation and autoimmune disease research due to the protein's role in regulating immune responses and extracellular signaling. The assay supports high-throughput analysis with high sensitivity and specificity, making it suitable for clinical research and drug development settings where monitoring S100A4 expression is critical.
