Prostate Apoptosis Response protein-4 Colorimetric Cell-Based ELISA Kit

The Prostate Apoptosis Response Protein 4 Colorimetric Cell-Based ELISA Kit is specifically designed for the detection of PDCD4 levels in prostate tissues and cell lysates. This kit offers high sensitivity and specificity, providing accurate and reproducible results for a variety of research applications.PDCD4, also known as Programmed Cell Death 4, is a tumor suppressor protein that plays a crucial role in regulating apoptosis and suppressing tumor growth. Dysregulation of PDCD4 has been linked to various cancer types, including prostate cancer, making it a valuable biomarker for studying disease progression and potential therapeutic interventions.

With this kit, researchers can effectively measure PDCD4 levels in prostate samples, offering valuable insights into the molecular mechanisms underlying cancer development and progression. By accurately quantifying PDCD4 expression, this kit enables researchers to further explore the role of PDCD4 in prostate cancer pathogenesis and evaluate its potential as a therapeutic target.

The Prostate Apoptosis Response protein-4 Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect Prostate Apoptosis Response protein-4 protein expression profile in cells. The kit can be used for measuring the relative amounts of Prostate Apoptosis Response protein-4 in cultured cells as well as screening for the effects that various treatments, inhibitors (ie siRNA or chemicals), or activators have on Prostate Apoptosis Response protein-4.

Qualitative determination of Prostate Apoptosis Response protein-4 concentration is achieved by an indirect ELISA format. In essence, Prostate Apoptosis Response protein-4 is captured by Prostate Apoptosis Response protein-4-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:PAR-4: a proapoptotic protein that drives trafficking and activation of Fas and Fasl to induce prostate cancer cell apoptosis and tumor regression. Capable of selectively inducing apoptosis in cancer cells, sensitizing the cells to diverse apoptotic stimuli and causing regression of tumors in animal models. Induces apoptosis in certain cancer cells by activation of the Fas prodeath pathway and coparallel inhibition of NF-kappaB transcriptional activity. Inhibits the transcriptional activation and augments the transcriptional repression mediated by WT1. Down-regulates the anti-apoptotic protein BCL2 via its interaction with WT1. Seems also to be a transcriptional repressor by itself. May be directly involved in regulating the amyloid precursor protein (APP) cleavage activity of BACE1.
UniProt Protein Details:

Protein type:Apoptosis

Chromosomal Location of Human Ortholog: 12q21

Cellular Component: cytoplasm; plasma membrane; actin filament; nucleus; actin cytoskeleton

Molecular Function:protein binding; leucine zipper domain binding; enzyme binding; actin binding; transcription corepressor activity

Biological Process: negative regulation of cell proliferation; actin filament bundle formation; negative regulation of T cell proliferation; interleukin-2 biosynthetic process; transcription, DNA-dependent; apoptosis; positive regulation of apoptosis; negative regulation of T cell receptor signaling pathway; negative regulation of B cell proliferation; negative regulation of transcription from RNA polymerase II promoter; positive regulation of amyloid precursor protein biosynthetic process

NCBI Summary:The tumor suppressor WT1 represses and activates transcription. The protein encoded by this gene is a WT1-interacting protein that itself functions as a transcriptional repressor. It contains a putative leucine zipper domain which interacts with the zinc finger DNA binding domain of WT1. This protein is specifically upregulated during apoptosis of prostate cells.

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-Prostate Apoptosis Response protein-4 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.
14.Wash 3 times with 200 µL of 1x Wash Buffer for 5 minutes each time.
15.Add 50 µL of Ready-to-Use Substrate to each well and incubate for 30 minutes at room temperature in the dark.
16.Add 50 µL of Stop Solution to each well and read OD at 450 nm immediately using the microplate reader.
