Used in immunological research to quantitatively measure CD177 protein levels in biological samples such as serum, plasma, or cell culture supernatants. The kit is particularly useful in studies related to neutrophil activation and function, as CD177 is expressed on a subset of neutrophils and involved in transendothelial migration and immune responses. It supports research into inflammatory diseases, autoimmune disorders, and infections where neutrophil behavior plays a critical role. The assay enables high-throughput analysis with high sensitivity and specificity, making it suitable for clinical and experimental investigations.
