PAK2 (Phospho-Ser141)Colorimetric Cell-Based ELISA Kit

The Human PAK2 (p21-activated kinase 2) Phospho-Ser141 Colorimetric Cell-Based ELISA Kit is a highly sensitive and specific assay designed for the accurate detection of phosphorylated PAK2 levels in cell lysates and tissue homogenates. This kit offers reliable and reproducible results, making it an ideal tool for studying the role of PAK2 phosphorylation in various cellular processes.PAK2 is a key signaling protein that regulates cell growth, survival, and cytoskeletal remodeling. Phosphorylation of PAK2 at Ser141 is known to enhance its kinase activity and is implicated in cancer progression, neurodegeneration, and immune response modulation.

Understanding the role of phosphorylated PAK2 in these processes is critical for developing targeted therapies and diagnostic tools.With its high sensitivity and specificity, the Human PAK2 Phospho-Ser141 Colorimetric Cell-Based ELISA Kit is a valuable research tool for investigating the functional significance of PAK2 phosphorylation and its potential as a therapeutic target in various diseases.

The PAK2 (Phospho-Ser141) Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect PAK2 protein phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated PAK2 in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on PAK2 phosphorylation.

Qualitative determination of PAK2 (Phospho-Ser141) concentration is achieved by an indirect ELISA format. In essence, PAK2 (Phospho-Ser141) is captured by PAK2 (Phospho-Ser141)-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.

NCBI Summary:The p21 activated kinases (PAK) are critical effectors that link Rho GTPases to cytoskeleton reorganization and nuclear signaling. The PAK proteins are a family of serine/threonine kinases that serve as targets for the small GTP binding proteins, CDC42 and RAC1, and have been implicated in a wide range of biological activities. The protein encoded by this gene is activated by proteolytic cleavage during caspase-mediated apoptosis, and may play a role in regulating the apoptotic events in the dying cell.

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.
