The MEF2A Phospho-Thr319 Colorimetric Cell-Based ELISA Kit is specifically designed for the quantitative detection of phosphorylated MEF2A (myocyte enhancer factor 2A) at threonine 319 in cell lysates. This kit offers high sensitivity and accuracy, allowing for reliable and reproducible results in a variety of research settings.MEF2A is a transcription factor that plays a critical role in regulating gene expression in response to various cellular signals. Phosphorylation of MEF2A at threonine 319 is known to modulate its activity and influence key biological processes such as cell differentiation, proliferation, and survival.

The detection of phosphorylated MEF2A at threonine 319 can provide valuable insights into the signaling pathways involved in cell growth, development, and disease progression. This makes the MEF2A Phospho-Thr319 Colorimetric Cell-Based ELISA Kit an indispensable tool for studying MEF2A-mediated signaling pathways and identifying potential therapeutic targets for various diseases, including cancer, cardiovascular disorders, and neurological conditions.

The MEF2A (Phospho-Thr319) Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect MEF2A protein phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated MEF2A in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on MEF2A phosphorylation.

Qualitative determination of MEF2A (Phospho-Thr319) concentration is achieved by an indirect ELISA format. In essence, MEF2A (Phospho-Thr319) is captured by MEF2A (Phospho-Thr319)-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:MEF2A: a myocyte-specific enhancing transcription factor which binds specifically to the MEF2 element present in the regulatory regions of many, if not all, muscle-specific genes. A member of the MADS gene family that also includes several homeotic genes and other transcription factors, all of which share a conserved DNA-binding domain. Five alternatively spliced isoforms have been reported.

NCBI Summary:The protein encoded by this gene is a DNA-binding transcription factor that activates many muscle-specific, growth factor-induced, and stress-induced genes. The encoded protein can act as a homodimer or as a heterodimer and is involved in several cellular processes, including muscle development, neuronal differentiation, cell growth control, and apoptosis. Defects in this gene could be a cause of autosomal dominant coronary artery disease 1 with myocardial infarction (ADCAD1). Several transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jan 2010]

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.
