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 Mouse AgRP. 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 Mouse AgRP 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 Mouse AgRP, 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 Mouse AgRP. The concentration of Mouse AgRP in the samples can be calculated by comparing the RLU of the samples to the standard curve.
| UniProt Protein Function: | Function: Plays a role in weight homeostasis. Involved in the control of feeding behavior through the central melanocortin system. Acts as alpha melanocyte-stimulating hormone antagonist by inhibiting cAMP production mediated by stimulation of melanocortin receptors within the hypothalamus and adrenal gland. Has very low activity with MC5R. Is an inverse agonist for MC3R and MC4R being able to suppress their constitutive activity |
| UniProt Protein Details: | By similarity. It promotes MC3R and MC4R endocytosis in an arrestin-dependent manner By similarity. Ref. 4 Subunit structure: Interacts with melanocortin receptors MC3R, MC4R and MC5R. Ref. 4 Subcellular location: Secreted. Golgi apparatus lumen By similarity. Tissue specificity: Expressed in arcuate nucleus and median eminence, adrenal gland (medulla), hypothalamus, testis, and lung. Induction: Hypothalamic expression is elevated circa 10-fold in ob/ob and db/db mice. Domain: The presence of a 'disulfide through disulfide knot' structurally defines this protein as a knottin By similarity. Sequence similarities: Contains 1 agouti domain. |
| NCBI Summary: | This gene encodes a protein that regulates feeding behavior and plays a key role in the control of body weight. The encoded protein acts as an antagonist of melanocortin receptor signaling. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Nov 2012] |

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.
