The p62 Dok (Phospho-Tyr362) Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect p62 Dok protein phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated p62 Dok in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on p62 Dok phosphorylation.
Qualitative determination of p62 Dok (Phospho-Tyr362) concentration is achieved by an indirect ELISA format. In essence, p62 Dok (Phospho-Tyr362) is captured by p62 Dok (Phospho-Tyr362)-specific primary (1ø) antibodies while the HRP-conjugated secondary (2ø) antibodies bind the Fc region of the 1ø antibody. Through this binding, the HRP enzyme conjugated to the 2ø 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: | DOK1: a docking protein that interacts with receptor tyrosine kinases. It is constitutively tyrosine phosphorylated in hematopoietic progenitors isolated from chronic myelogenous leukemia (CML) patients in the chronic phase. It may be a critical substrate for p210(bcr/abl), a chimeric protein whose presence is associated with CML. Docking protein 1 contains a putative pleckstrin homology domain at the amino terminus and ten PXXP SH3 recognition motifs. Docking protein 2 binds p120 (RasGAP) from CML cells. It has been postulated to play a role in mitogenic signaling. |
| UniProt Protein Details: | Protein type:Motility/polarity/chemotaxis; Adaptor/scaffold Chromosomal Location of Human Ortholog: 2p13 Cellular Component: perinuclear region of cytoplasm; cytoplasm; cytosol; nucleus Molecular Function:protein binding; receptor signaling protein activity; insulin receptor binding Biological Process: cell surface receptor linked signal transduction; Ras protein signal transduction; insulin receptor signaling pathway; signal transduction; transmembrane receptor protein tyrosine kinase signaling pathway |
| NCBI Summary: | The protein encoded by this gene is part of a signal transduction pathway downstream of receptor tyrosine kinases. The encoded protein is a scaffold protein that helps form a platform for the assembly of multiprotein signaling complexes. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2010] |

| 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. |

| 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. |
