Anti-lacritin antibodies are used for the immunodetection of the protein encoded by the LACRT gene. In humans, the canonical protein has a reported length of 138 amino acid residues and a mass of 14.2 kDa. It is known to be a secreted protein. It is reported to be expressed in secretory granules of many acinar cells in lacrimal gland and in scattered acinar cells of salivary glands. It is noted to be involved in the regulation of apoptosis and the regulation of cell proliferation. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include extracellular glycoprotein lacritin. Western Blot is a widely used application for the lacritin antibodies listed below. In addition, Immunohistochemistry is also a common application.
