This kit uses Sandwich-CLIA as the method. The micro CLIA plate provided in this kit has been pre-coated with an antibody specific to Human GLRX3. Standards or samples are added to the appropriate micro CLIA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human GLRX3 and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well successively and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human GLRX3, biotinylated detection antibody and Avidin-HRP conjugate will appear fluorescence. The Relative light unit (RLU) value is measured spectrophotometrically by the Chemiluminescence immunoassay analyzer. The RLU value is positively associated with the concentration of Human GLRX3. The concentration of Human GLRX3 in the samples can be calculated by comparing the RLU of the samples to the standard curve.
UniProt Protein Function: | GLRX3: Critical negative regulator of cardiac hypertrophy and a positive inotropic regulator. May play a role in regulating the function of the thioredoxin system. Does not posses any thyoredoxin activity since it lacks the conserved motif that is essential for catalytic activity. |
UniProt Protein Details: | Protein type:Oxidoreductase Chromosomal Location of Human Ortholog: 10q26 Cellular Component: cell cortex; Z disc Molecular Function:protein binding; electron carrier activity; protein kinase C binding; metal ion binding; iron-sulfur cluster binding; protein disulfide oxidoreductase activity Biological Process: cell redox homeostasis; regulation of the force of heart contraction |
NCBI Summary: | This gene encodes a member of the glutaredoxin family. Glutaredoxins are oxidoreductase enzymes that reduce a variety of substrates using glutathione as a cofactor. The encoded protein binds to and modulates the function of protein kinase C theta. The encoded protein may also inhibit apoptosis and play a role in cellular growth, and the expression of this gene may be a marker for cancer. Pseudogenes of this gene are located on the short arm of chromosomes 6 and 9. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Dec 2010] |

As the RLU values of the standard curve may vary according to the conditions of the actual assay performance (e. g. operator, pipetting technique, washing technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data is provided below for reference only.
