Description
GluR2 (Phospho-Ser880)Cell-Based ELISA Kit
The GluR2 (Phospho-Ser880)Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can monitor GluR2 (Phospho-Ser880)protein expression profile in cells. The kit can be used for measuring the relative amounts of GluR2 (Phospho-Ser880)in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on GluR2 phosphorylation.
How does our GluR2 (Phospho-Ser880)Colorimetric Cell-Based ELISA Kit work?
Qualitative determination of GluR2 (Phospho-Ser880)concentration is achieved by an indirect ELISA format. In essence, GluR2 (Phospho-Ser880)is captured by GluR2 (Phospho-Ser880) -specific primary (1°) antibodies while the HRP-conjugated secondary (2°) antibodies bind the Fc region of the 1° antibody. Through this binding, the HRP enzyme conjugated to the 2° antibody can catalyze a colorimetric reaction upon substrate addition. Due to the qualitative nature of the Cell-Based ELISA, multiple normalization methods are needed:
| 1. | A monoclonal antibody specific for human GAPDH is included to serve as an internal positive control in normalizing the target absorbance values. |
| 2. | Following the colorimetric measurement of HRP activity via substrate addition, the Crystal Violet whole-cell staining method may be used to determine cell density. After staining, the results can be analysed by normalizing the absorbance values to cell amounts, by which the plating difference can be adjusted. |

Kit Protocol
This is a summarized version of the kit protocol. Please view the technical manual of this kit for information on sample preparation, reagent preparation and plate lay out.
| 1. | Seed 200 µl of 20,000 adherent cells in culture medium in each well of a 96-well plate. The plates included in the kit are sterile and treated for cell culture. For suspension cells and loosely attached cells, coat the plates with 100 µl of 10 µg/ml Poly-L-Lysine (not included) to each well of a 96-well plate for 30 minutes at 37°C prior to adding cells. |
| 2. | Incubate the cells for overnight at 37°C, 5% CO2. |
| 3. | Treat the cells as desired. |
| 4. | Remove the cell culture medium and rinse with 200 µl of 1x TBS, twice. |
| 5. | Fix the cells by incubating with 100 µl of Fixing Solution for 20 minutes at room temperature. The 4% formaldehyde is used for adherent cells and 8% formaldehyde is used for suspension cells and loosely attached cells. |
| 6. | Remove the Fixing Solution and wash the plate 3 times with 200 µl 1x Wash Buffer for five minutes each time with gentle shaking on the orbital shaker. The plate can be stored at 4°C for a week. |
| 7. | Add 100 µl of Quenching Buffer and incubate for 20 minutes at room temperature. |
| 8. | Wash the plate 3 times with 1x Wash Buffer for 5 minutes each time. |
| 9. | Add 200 µl of Blocking Buffer and incubate for 1 hour at room temperature. |
| 10. | Wash 3 times with 200 µl of 1x Wash Buffer for 5 minutes each time. |
| 11. | Add 50 µl of 1x primary antibodies Anti-GluR2 (Phospho-Ser880)Antibody, Anti-GluR2 Antibody and/or Anti-GAPDH Antibody) to the corresponding wells, cover with Parafilm and incubate for 16 hours (overnight) at 4°C. If the target expression is known to be high, incubate for 2 hours at room temperature. |
| 12. | Wash 3 times with 200 µl of 1x Wash Buffer for 5 minutes each time. |
| 13. | Add 50 µl of 1x secondary antibodies (HRP-Conjugated AntiRabbit IgG Antibody or HRP-Conjugated Anti-Mouse IgG Antibody) to corresponding wells and incubate for 1.5 hours at room temperature. |

GluR2 (Phospho-Ser880)- Protein Information
| UniProt Protein Function: | GluR2: an integral membrane protein belonging to the glutamate-gated ion channel family. L-glutamate (Glu) acts as an excitatory neurotransmitter at many synapses in the central nervous system. Glutamate receptors are heteromeric protein complexes with multiple subunits, each possessing transmembrane regions, and all arranged to form a ligand-gated ion channel. The postsynaptic actions of Glu are mediated by a variety of receptors that are named according to their selective agonists. This receptor binds AMPA(quisqualate) > glutamate > kainate. Each of the four GluR proteins (GRIA1-4) include flip and flop isoforms generated by alternative RNA splicing. |
| UniProt Protein Details: | Protein type:Channel, calcium; Membrane protein, integral; Membrane protein, multi-pass; Channel, ligand-gated Chromosomal Location of Human Ortholog: 4q32.1 Cellular Component: cell junction; endoplasmic reticulum membrane; integral to plasma membrane; plasma membrane; postsynaptic membrane Molecular Function:alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionate selective glutamate receptor activity; excitatory extracellular ligand-gated ion channel activity; extracellular-glutamate-gated ion channel activity; ionotropic glutamate receptor activity; protein binding Biological Process: ionotropic glutamate receptor signaling pathway; signal transduction; synaptic transmission |
| NCBI Summary: | Glutamate receptors are the predominant excitatory neurotransmitter receptors in the mammalian brain and are activated in a variety of normal neurophysiologic processes. This gene product belongs to a family of glutamate receptors that are sensitive to alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionate (AMPA), and function as ligand-activated cation channels. These channels are assembled from 4 related subunits, GRIA1-4. The subunit encoded by this gene (GRIA2) is subject to RNA editing (CAG->CGG; Q->R) within the second transmembrane domain, which is thought to render the channel impermeable to Ca(2+). Human and animal studies suggest that pre-mRNA editing is essential for brain function, and defective GRIA2 RNA editing at the Q/R site may be relevant to amyotrophic lateral sclerosis (ALS) etiology. Alternative splicing, resulting in transcript variants encoding different isoforms, (including the flip and flop isoforms that vary in their signal transduction properties), has been noted for this gene.
