The ATRIP (Phospho-Ser224) Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect ATRIP protein phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated ATRIP in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on ATRIP phosphorylation.

Qualitative determination of ATRIP (Phospho-Ser224) concentration is achieved by an indirect ELISA format. In essence, ATRIP (Phospho-Ser224) is captured by ATRIP (Phospho-Ser224)-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.

Gene Symbol:ATRIP
Sub Type:Phospho
UniProt Protein Function:ATRIP: is required for checkpoint signaling after DNA damage. Required for ATR expression, possibly by stabilizing the protein. Heterodimerizes with ATR. The heterodimer binds replication protein A (RPA), a protein complex that subsequently is recruited to single stranded DNA (ssDNA). Its EEXXXDDL motif is required for the interaction with catalytic subunit of DNA-PK and its recruitment to sites of DNA damage. e for this protein is either identical to or adjacent to that of ATRIP. Some of the mRNAs that encode ATRIP also encode TREX1 in another reading frame. Three alternatively spliced human isoforms have been reported.
UniProt Protein Details:

Protein type:DNA-binding; DNA repair, damage; Cell cycle regulation

Chromosomal Location of Human Ortholog: 3p21.31

Cellular Component: nucleoplasm; nucleus

Molecular Function:protein binding

Biological Process: DNA damage checkpoint; DNA repair; DNA replication

NCBI Summary:This gene encodes an essential component of the DNA damage checkpoint. The encoded protein binds to single-stranded DNA coated with replication protein A. The protein also interacts with the ataxia telangiectasia and Rad3 related protein kinase, resulting in its accumulation at intranuclear foci induced by DNA damage. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2012]

StepProcedure
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-ATRIP (Phospho-Ser224) Antibody, Anti-ATRIP 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.
