Clusterin Monoclonal Antibody (Clone 9E2E2)

Clusterin is a secreted heterodimeric glycoprotein.¹ It is proteolytically processed to remove a signal peptide and cleave the α and β chains.^1,2 This cleavage creates small- and medium-sized isoforms found in the nucleus or cytosol and mitochondria, respectively, and a large-sized isoform composed of α- and β chains linked via disulfide bonds near the center that is secreted outside the cell.² Clusterin is ubiquitously expressed in tissues and found in physiological fluids. It is a multifunctional protein involved in a wide range of processes, including immune modulation, autophagosome formation, apoptosis, and extracellular matrix remodeling, among others.³ Clusterin is upregulated by cellular stress and acts as an extracellular chaperone and scavenger to prevent protein aggregation. SNPs in CLU, the gene encoding clusterin, are associated with a higher rate of cognitive decline in patients with mild cognitive decline or Alzheimer's disease.⁴ Clusterin is also associated with inflammatory and cardiovascular diseases, where it has either protective or detrimental effects.² Cayman's Clusterin Monoclonal Antibody (Clone 9E2E2) can be used for flow cytometry (FC), ELISA, immunocytochemistry (ICC), immunofluorescence (IF), and Western blot (WB) applications.
