The NFAT3 (Phospho-Ser676) Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect NFAT3 protein phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated NFAT3 in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on NFAT3 phosphorylation.

Qualitative determination of NFAT3 (Phospho-Ser676) concentration is achieved by an indirect ELISA format. In essence, NFAT3 (Phospho-Ser676) is captured by NFAT3 (Phospho-Ser676)-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:NFAT3: a transcription factor that plays a role in the inducible expression of cytokine genes in T cells, especially in the induction of the IL-2 and IL-4. Also control gene expression in embryonic cardiac cells. Could regulate not only the activation and proliferation but also the differentiation and programmed death of lymphoid and nonlymphoid cells. Highly expressed in placenta, lung, kidney, testis and ovary. Weakly expressed in spleen and thymus. Not expressed in peripheral blood lymphocytes. 23 alternatively spliced isoforms of the human protein hve been reported.

NCBI Summary:This gene encodes a member of the nuclear factor of activated T cells (NFAT) protein family. The encoded protein is part of a DNA-binding transcription complex. This complex consists of at least two components: a preexisting cytosolic component that translocates to the nucleus upon T cell receptor stimulation and an inducible nuclear component. NFAT proteins are activated by the calmodulin-dependent phosphatase, calcineurin. The encoded protein plays a role in the inducible expression of cytokine genes in T cells, especially in the induction of interleukin-2 and interleukin-4. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]

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.
