(anti-Human and others as indicated)

RDI Divison of researchd Industries Intl  offers a wide line of  antibodies. Since no one antibody works best for all applications (neutralization, blotting, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below.

Anti-CLUSTERIN antibodies  (see 1 polyclonal and 4monoclonals below)
-Clusterin (also known as dimeric acidic glycoprotein, testosterone repressed prostate message-2, and sulfated glycoprotein-2) is a disulfide linked heterodimeric sulfated glycoprotein. Clusterin binds to cells, membranes, and hydrophobic proteins, and inhibits complement activation. Eleveated clusterin expression, and particularly retrograde transport of cluserin from the ER to the nucleus, has been associated with apoptosis.

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.Also,when expression is upregulated this tends to correlate inversely with apoptotic index.This seems to indicate that clusterin expression is not a prerequisite to cellular death by apoptosis.Instead it may have a role in tumorigenesis and progression and also estrogen and progesterone receptor negativity.Clusterin is also implicated with endometrial cancers,myocardial infarction,renal diseases and atherosclerosis.Clusterin has also been shown to be a useful marker of anaplastic large cell lymphoma.

Background: Clusterin, also designated dimeric acidic glycoprotein (DAG), testosterone repressed prostate message-2 (TRPM-2) apolipoprotein J and sulfated glycoprotein-2, is expressed in a variety of tissues as a disulfide-linked heterodimeric sulfated glycoprotein. Highest expression of clusterin is detected in stomach,brain,liver and testes. Proposed functions of this protein include the transport of lipoproteins, the inhibition of complement- mediated cell lysis and the modulation of cell-cell interactions. Clusterin is a putative marker for cells undergoing apoptosis. Clusterin has also been shown to be induced after tissue injury and in many disease states such as Alzheimer's disease. Clusterin is associated with amyloid-beta plaques in Alzheimer diseased brain.
