Anti-EMI antibodies are used in antigen-specific immunodetection in biological samples. The target EMI is a known alias name of the protein elastin microfibril interfacer 1, encoded by the EMILIN1 gene in humans. This 1016-amino acid residue protein is believed to be responsible for anchoring smooth muscle cells to elastic fibers, and may be involved not only in the formation of the elastic fiber, but also in the processes that regulate vessel assembly. It is localized to the extracellular matrix and is secreted of the cell and features glycosylated post-translational modifications. It is reported to be expressed in many tissues, such as the colon and rectum. The term EMILIN is another synonym for EMI. ELISA, Western Blot, and Immunohistochemistry are common applications for EMI antibodies.
