The DAPP1 (Phospho-Tyr139) Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect DAPP1 protein phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated DAPP1 in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on DAPP1 phosphorylation.
Qualitative determination of DAPP1 (Phospho-Tyr139) concentration is achieved by an indirect ELISA format. In essence, DAPP1 (Phospho-Tyr139) is captured by DAPP1 (Phospho-Tyr139)-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. |
