Used in immunological research to study CCR7 receptor expression on immune cells, particularly in T cells and dendritic cells. Helps investigate lymphocyte trafficking, immune cell migration to lymphoid organs, and tumor metastasis in cancers where CCR7 is overexpressed. Employed in flow cytometry, immunohistochemistry, and blocking assays to modulate CCR7-mediated signaling. Also utilized in the development of therapeutic antibodies targeting autoimmune diseases and cancer immunotherapy by interfering with CCR7-dependent cell migration.
