Clusterin BioAssay(TM) ELISA Kit (Rat)

Clusterin (apolipoprotein J) is a 75-80kD disulfide-linked heterodimeric protein associated with the clearance of cellular debris and apoptosis. In humans, clusterin is encoded by the CLU gene.This protein has several synonyms: dimeric acidic glycoprotein (DAG protein), testosterone repressed prostate message-2 (TRPM-2), sulfated glycoprotein-2 (SGP-2) and complement lysis inhibitor (CLI). Clusterin was mapped to mouse chromosome 14. Clusterin is a ubiquitously expressed molecule thought to influence a variety of processes including cell death. In the brain, it accumulates in dying neurons following seizures and hypoxic-ischemic (H-I) injury. clusterin may be a new therapeutic target to modulate non-caspase-dependent neuronal death following acute brain injury. Sample Type: Cell culture supernates, serum, plasma (Heparin or EDTA). Intended Use: Sandwich High Sensitivity BioAssay(TM) ELISA kit for Quantitative Detection of Rat Clusterin. Sensitivity: <15pg/ml, Range: 312pg/ml-20,000pg/ml, Specificity: Recognizes natural and recombinant Rat Clusterin. There is no detectable cross-reactivity with other relevant proteins. Test Principle: This Rat Clusterin BioAssay(TM) ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A a monoclonal antibody from mouse specific for Clusterin has been precoated onto 96-well plates. Standards(Expression system for standard: NSO, Immunogen sequence: D22-R226 (beta) & S227-E448 (alpha)) and test samples are added to the wells, a biotinylated detection a biotinylated polyclonal antibody from goat specific for Clusterin is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the Rat Clusterin amount of sample captured in plate.
