MED1 Colorimetric Cell-Based ELISA

The MED1 Colorimetric Cell-Based ELISA Kit is specifically designed for the precise measurement of MED1 levels in cell lysates and tissue samples. This kit offers exceptional sensitivity and specificity, guaranteeing accurate and consistent results for a variety of research applications.MED1 is a key mediator of gene transcription and cell signaling pathways, playing a crucial role in regulating cell growth, differentiation, and survival.

Dysregulation of MED1 has been implicated in various diseases, including cancer, diabetes, and inflammatory disorders, making it a valuable target for therapeutic interventions and biomarker studies.With its user-friendly protocol and reliable performance, the MED1 Colorimetric Cell-Based ELISA Kit is an indispensable tool for researchers looking to investigate the role of MED1 in disease pathogenesis and therapeutic development.

The MED1 Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect MED1 protein expression profile in cells. The kit can be used for measuring the relative amounts of MED1 in cultured cells as well as screening for the effects that various treatments, inhibitors (ie siRNA or chemicals), or activators have on MED1.

Qualitative determination of MED1 concentration is achieved by an indirect ELISA format. In essence, MED1 is captured by MED1-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:MED1: a subunit of the CRSP (cofactor required for SP1 activation) complex, which, along with TFIID, is required for efficient activation by SP1. Also is a component of other multisubunit complexes e.g. thyroid hormone receptor- (TR-) associated proteins which interact with TR and facilitate TR function on DNA templates in conjunction with initiation factors and cofactors. May regulates p53-dependent apoptosis. Is essential for adipogenesis. This protein is known to have the ability to self-oligomerize. Two splice-variant isoforms have been described.

NCBI Summary:The activation of gene transcription is a multistep process that is triggered by factors that recognize transcriptional enhancer sites in DNA. These factors work with co-activators to direct transcriptional initiation by the RNA polymerase II apparatus. The protein encoded by this gene is a subunit of the CRSP (cofactor required for SP1 activation) complex, which, along with TFIID, is required for efficient activation by SP1. This protein is also a component of other multisubunit complexes e.g. thyroid hormone receptor-(TR-) associated proteins which interact with TR and facilitate TR function on DNA templates in conjunction with initiation factors and cofactors. It also regulates p53-dependent apoptosis and it is essential for adipogenesis. This protein is known to have the ability to self-oligomerize. [provided by RefSeq, Jul 2008]

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.
