General description

Clusterin is also known as apolipoprotein J, complement lysis inhibitor, gp80, glycoprotein III, SGP-2, SP 40-40, TRPM2 and T64. It is a ubiquitous multifunctional protein of 80kD comprising of two disulfide-linked subunits, alpha and beta, and capable of interacting with a broad range of molecules. It is implicated in numerous biological processes including sperm maturation, lipid transport, regulation of the complement cascade, membrane recycling, cell death, immune regulation, cell adhesion and morphological transformation. In pathological conditions, it is an amyloid associated protein co-localising with fibrillar deposits in systemic and localised amyloid disorders. In Alzheimer ’s disease, clusterin is present in amyloid plaques and cerebrovascular deposits. In breast cancers, clusterin expression was found to correlate with tumour size. Clusterin is also implicated with endometrial cancers, myocardial infarction, renal diseases and atherosclerosis.


This antibody recognizes human clusterin α chain, Mr 40 kDa, and precursor protein.
