Used in biomedical research to detect and quantify TSPAN1 protein levels in human biological samples such as serum, plasma, and cell lysates. This ELISA kit is particularly useful in studies related to cancer research, as TSPAN1, a member of the tetraspanin family, is involved in cell proliferation, migration, and tumor progression. It enables researchers to assess TSPAN1 expression in various disease states, supporting investigations into its role as a potential biomarker or therapeutic target. The assay provides a sensitive and specific method for high-throughput analysis in clinical and experimental settings.
