Description
IkappaB-epsilon Colorimetric Cell-Based ELISA Kit
The IKK alpha/beta/epsilon Colorimetric Cell-Based ELISA Kit is a powerful tool for researchers looking to study the IKK signaling pathway in detail. This kit allows for the detection of IKK alpha, beta, and epsilon levels in cell lysates with high sensitivity and specificity. By accurately measuring the activity of these key kinases, researchers can gain valuable insights into the regulation of inflammation, immune response, and cell survival.The IKK signaling pathway is known for its important role in various biological processes, including the regulation of NF-kB signaling and the control of gene expression.
Dysregulation of this pathway has been implicated in a range of diseases, including cancer, autoimmune disorders, and inflammatory conditions. By using the IKK alpha/beta/epsilon Colorimetric Cell-Based ELISA Kit, researchers can further our understanding of these diseases and potentially identify new targets for therapeutic intervention.

The IkappaB-epsilon Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect IkappaB-epsilon protein expression profile in cells. The kit can be used for measuring the relative amounts of IkappaB-epsilon in cultured cells as well as screening for the effects that various treatments, inhibitors (ie siRNA or chemicals), or activators have on IkappaB-epsilon.
Qualitative determination of IkappaB-epsilon concentration is achieved by an indirect ELISA format. In essence, IkappaB-epsilon is captured by IkappaB-epsilon-specific primary antibodies while the HRP-conjugated secondary antibodies bind the Fc region of the primary antibody. Through this binding, the HRP enzyme conjugated to the secondary 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. |

| UniProt Protein Function: | IkB-epsilon: Inhibits NF-kappa-B by complexing with and trapping it in the cytoplasm. Inhibits DNA-binding of NF-kappa-B p50-p65 and p50-c-Rel complexes. Interacts with RELA, REL, NFKB1 nuclear factor NF-kappa-B p50 subunit and NFKB2 nuclear factor NF-kappa-B p52 subunit. Highly expressed in spleen, testis and lung, followed by kidney, pancreas, heart, placenta and brain. Also expressed in granulocytes and macrophages. Belongs to the NF-kappa-B inhibitor family. |
| UniProt Protein Details: | Protein type:DNA-binding; Inhibitor Chromosomal Location of Human Ortholog: 6p21.1 Cellular Component: cytoplasm; cytosol Molecular Function:protein binding Biological Process: cytoplasmic sequestering of transcription factor |
| NCBI Summary: | The protein encoded by this gene binds to components of NF-kappa-B, trapping the complex in the cytoplasm and preventing it from activating genes in the nucleus. Phosphorylation of the encoded protein targets it for destruction by the ubiquitin pathway, which activates NF-kappa-B by making it available to translocate to the nucleus.

| Step | Procedure |
| 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. |

| 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-IkappaB-epsilon 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. |
| 14. | Wash 3 times with 200 µL of 1x Wash Buffer for 5 minutes each time. |
| 15. | Add 50 µL of Ready-to-Use Substrate to each well and incubate for 30 minutes at room temperature in the dark. |
