This ELISA kit uses Sandwich-ELISA as the method. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human ADORA1. Standards or samples are added to the appropriate micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human ADORA1 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 ADORA1, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by adding Stop Solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human ADORA1. The concentration of Human ADORA1 in samples can be calculated by comparing the OD of the samples to the standard curve.
| UniProt Protein Function: | ADORA1: Receptor for adenosine. The activity of this receptor is mediated by G proteins which inhibit adenylyl cyclase. Belongs to the G-protein coupled receptor 1 family. 2 isoforms of the human protein are produced by alternative splicing. |
| UniProt Protein Details: | Protein type:Membrane protein, integral; Membrane protein, multi-pass; Endoplasmic reticulum; Receptor, GPCR; Apoptosis; GPCR, family 1 Chromosomal Location of Human Ortholog: 1q32. 1 Cellular Component: integral to plasma membrane; plasma membrane Molecular Function:protein binding Biological Process: cell-cell signaling; inflammatory response; nervous system development; phagocytosis; signal transduction |
| NCBI Summary: | The protein encoded by this gene is an adenosine receptor that belongs to the G-protein coupled receptor 1 family. There are 3 types of adenosine receptors, each with a specific pattern of ligand binding and tissue distribution, and together they regulate a diverse set of physiologic functions. The type A1 receptors inhibit adenylyl cyclase, and play a role in the fertilization process. Animal studies also suggest a role for A1 receptors in kidney function and ethanol intoxication. Transcript variants with alternative splicing in the 5' UTR have been found for this gene. [provided by RefSeq, Jul 2008] |

As the OD 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.
