      Background InformationClusterin 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.

      I would like to use this monoclonal antibody on mouse tissue, are there any special procedures I should follow?To reduce the background interaction between the monoclonal antibody and the mouse tissue, you will need to perform antigen retrieval and use a special secondary antibody. For antigen retrieval, prepare a citrate buffer by mixing 19ml of 0.1M citric acid and 82ml of 0.1M sodium citrate to make 1000ml of buffer. Adjust the pH to 6.0 before each use. Add buffer to your slide. Using an 800 watt microwave oven with rotation, microwave for 7.5 min at high, 5 min at 50% (3 cycles), checking the slide at the end of each cycle to see if the solution needs to be replaced, adding water if needed. For the secondary antibody, use a biotinylated isotype specific secondary IGG (IGG-1) and a 3% donkey serum block. This will help reduce the background issues using mouse monoclonals.
