p47 phox (Phospho-Ser359)Colorimetric Cell-Based ELISA Kit

The p47-phox Phospho-Ser359 Colorimetric Cell-Based ELISA Kit is a powerful tool for detecting and measuring levels of phosphorylated p47-phox protein in cell lysates. This kit offers high sensitivity and specificity, ensuring accurate and reproducible results for researchers studying cellular responses to oxidative stress and immune cell activation.p47-phox is a critical component of the NADPH oxidase complex, which generates reactive oxygen species (ROS) essential for immune defense and signaling pathways. Phosphorylation of p47-phox at Ser359 is a key regulatory event in the activation of NADPH oxidase, making this kit an invaluable tool for understanding the molecular mechanisms underlying oxidative stress-related diseases such as inflammation, cardiovascular disorders, and neurodegenerative diseases.

With the p47-phox Phospho-Ser359 Colorimetric Cell-Based ELISA Kit, researchers can accurately quantify phosphorylated p47-phox levels in cell samples, providing valuable insights into the role of NADPH oxidase activation in cellular pathways and disease processes.

The p47 phox (Phospho-Ser359) Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect p47 phox protein phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated p47 phox in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on p47 phox phosphorylation.

Qualitative determination of p47 phox (Phospho-Ser359) concentration is achieved by an indirect ELISA format. In essence, p47 phox (Phospho-Ser359) is captured by p47 phox (Phospho-Ser359)-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:p47phox: the 47-kilodalton cytosolic subunit of the multi-protein complex known as NADPH oxidase found in neutrophils. The holo-oxidase produces a burst of superoxide which is delivered to the lumen of the neutrophil phagosome. Contains 2 SH2 domains. Mutations in NCF1, as well as in other NADPH oxidase subunits, can result in chronic granulomatous disease.

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.
