The RAD17 Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect RAD17 protein expression profile in cells. The kit can be used for measuring the relative amounts of RAD17 in cultured cells as well as screening for the effects that various treatments, inhibitors (ie siRNA or chemicals), or activators have on RAD17.
Qualitative determination of RAD17 concentration is achieved by an indirect ELISA format. In essence, RAD17 is captured by RAD17-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: | RAD17: a cell cycle checkpoint gene required for cell cycle arrest and DNA damage repair in response to DNA damage. Shares strong similarity with DNA replication factor C (RFC), and can form a complex with RFCs. Binds to chromatin prior to DNA damage and is phosphorylated by ATR after the damage. Phosphorylated and activated after DNA damage, inducing cell cycle G2 arrest. Eight alternatively spliced variants have been reported. |
| UniProt Protein Details: | Protein type:Cell cycle regulation Chromosomal Location of Human Ortholog: 5q13 Cellular Component: nucleoplasm; chromosome, telomeric region; nucleus Molecular Function:protein binding; ATP binding Biological Process: regulation of phosphorylation; negative regulation of DNA replication; mitotic cell cycle checkpoint; DNA damage checkpoint; DNA repair; DNA replication; DNA replication checkpoint; response to DNA damage stimulus |
| NCBI Summary: | The protein encoded by this gene is highly similar to the gene product of Schizosaccharomyces pombe rad17, a cell cycle checkpoint gene required for cell cycle arrest and DNA damage repair in response to DNA damage. This protein shares strong similarity with DNA replication factor C (RFC), and can form a complex with RFCs. This protein binds to chromatin prior to DNA damage and is phosphorylated by the checkpoint kinase ATR following damage. This protein recruits the RAD1-RAD9-HUS1 checkpoint protein complex onto chromatin after DNA damage, which may be required for its phosphorylation. The phosphorylation of this protein is required for the DNA-damage-induced cell cycle G2 arrest, and is thought to be a critical early event during checkpoint signaling in DNA-damaged cells. Multiple alternatively spliced transcript variants of this gene, which encode four distinct protein isoforms, have been reported. Two pseudogenes, located on chromosomes 7 and 13, have been identified. [provided by RefSeq, Jul 2013] |

| 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. |
