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 FABP3. 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 FABP3 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 FABP3, 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 FABP3. The concentration of Human FABP3 in the samples can be calculated by comparing the RLU of the samples to the standard curve.
| UniProt Protein Function: | FABP3: FABP are thought to play a role in the intracellular transport of long-chain fatty acids and their acyl-CoA esters. Belongs to the calycin superfamily. Fatty-acid binding protein (FABP) family. |
| UniProt Protein Details: | Protein type:Lipid-binding Chromosomal Location of Human Ortholog: 1p33-p32 Cellular Component: extracellular space; sarcoplasm; cytosol Molecular Function:protein binding; icosatetraenoic acid binding; cytoskeletal protein binding; long-chain fatty acid transporter activity Biological Process: response to drug; negative regulation of cell proliferation; cholesterol homeostasis; regulation of fatty acid oxidation; fatty acid metabolic process; response to insulin stimulus; phospholipid homeostasis |
| NCBI Summary: | The intracellular fatty acid-binding proteins (FABPs) belongs to a multigene family. FABPs are divided into at least three distinct types, namely the hepatic-, intestinal- and cardiac-type. They form 14-15 kDa proteins and are thought to participate in the uptake, intracellular metabolism and/or transport of long-chain fatty acids. They may also be responsible in the modulation of cell growth and proliferation. Fatty acid-binding protein 3 gene contains four exons and its function is to arrest growth of mammary epithelial cells. This gene is a candidate tumor suppressor gene for human breast cancer. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2016] |

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.
