Anti-proteoglycan 3 antibodies are used in antigen-specific immunodetection in biological samples. The target proteoglycan 3 is a known alias name of the protein proteoglycan 3, pro eosinophil major basic protein 2, encoded by the PRG3 gene in humans. This 225-amino acid residue protein is known to be involved in immune response pathways, among other biological processes. It is localized to the cytoplasm of the cell. In terms of tissue expression, it is reported to be expressed in bone marrow. Other synonyms for proteoglycan 3 include MBP2, MBPH, and proteoglycan 3. Indicated applications for proteoglycan 3 antibodies listed below include Western Blot and Immunohistochemistry.
