Anti-GARI-L4 antibodies are used in antigen-specific immunodetection in biological samples. The target GARI-L4 is a known alias name of the protein golgi associated RAB2 interactor family member 4, encoded by the GARIN4 gene in humans. This 594-amino acid residue protein is known to be involved in Golgi organization, among other biological processes. It is localized to the Golgi of the cell. It is reported to be expressed in the testis.
