The Dynamin-1 Phospho-Ser774 Colorimetric Cell-Based ELISA Kit is specifically designed for the detection of phosphorylated Dynamin-1 at Ser774 in cell lysates. This kit provides high sensitivity and specificity, allowing for the accurate measurement of Dynamin-1 phosphorylation levels in a variety of cell types.Dynamin-1 is a key regulator of endocytosis and membrane trafficking, playing a critical role in synaptic transmission and vesicle recycling. Phosphorylation of Dynamin-1 at Ser774 is known to modulate its function and is implicated in various neurological disorders such as Alzheimer's disease and Parkinson's disease.

By utilizing the Dynamin-1 Phospho-Ser774 Colorimetric Cell-Based ELISA Kit, researchers can gain valuable insights into the regulatory mechanisms of Dynamin-1 phosphorylation and its implications in disease pathology. With its reliability and reproducibility, this kit is an essential tool for investigating the role of Dynamin-1 in cellular processes and developing potential therapeutic strategies.

The Dynamin-1 (Phospho-Ser774) Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect Dynamin-1 protein phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated Dynamin-1 in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on Dynamin-1 phosphorylation.

Qualitative determination of Dynamin-1 (Phospho-Ser774) concentration is achieved by an indirect ELISA format. In essence, Dynamin-1 (Phospho-Ser774) is captured by Dynamin-1 (Phospho-Ser774)-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.

NCBI Summary:This gene encodes a member of the dynamin subfamily of GTP-binding proteins. The encoded protein possesses unique mechanochemical properties used to tubulate and sever membranes, and is involved in clathrin-mediated endocytosis and other vesicular trafficking processes. Actin and other cytoskeletal proteins act as binding partners for the encoded protein, which can also self-assemble leading to stimulation of GTPase activity. More than sixty highly conserved copies of the 3' region of this gene are found elsewhere in the genome, particularly on chromosomes Y and 15. Alternatively spliced transcript variants encoding different isoforms have been described. [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.
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.

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.
