PRG4 (N-Term) antibody targets the N-terminal region of proteoglycan 4 (PRG4), a glycoprotein also known as lubricin. PRG4 is primarily secreted by synovial fibroblasts and superficial zone chondrocytes in joints, playing a critical role in maintaining tissue lubrication, reducing friction, and protecting articular surfaces. It is essential for joint homeostasis, as it prevents protein deposition, inhibits cell adhesion, and regulates inflammatory responses in synovial fluid. Mutations or deficiencies in PRG4 are linked to joint pathologies, including camptodactyly-arthropathy-coxa vara-pericarditis syndrome and osteoarthritis.
The N-Term-specific antibody recognizes epitopes within the N-terminal domain of PRG4. enabling researchers to study its expression, localization, and function. This antibody is widely used in applications like Western blotting, immunohistochemistry, and immunofluorescence to investigate PRG4’s role in healthy and diseased tissues. Its specificity for the N-terminal region ensures detection of full-length PRG4 or its cleavage products, aiding in studies on post-translational modifications or proteolytic processing. Research utilizing this antibody has advanced understanding of joint lubrication mechanisms, cartilage degeneration, and potential therapeutic strategies for musculoskeletal disorders. Validation in relevant species and sample types is recommended to ensure experimental accuracy.
