The Calsenilin/KCNIP3 (Phospho-Ser63) Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect Calsenilin/KCNIP3 protein phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated Calsenilin/KCNIP3 in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on Calsenilin/KCNIP3 phosphorylation.
Qualitative determination of Calsenilin/KCNIP3 (Phospho-Ser63) concentration is achieved by an indirect ELISA format. In essence, Calsenilin/KCNIP3 (Phospho-Ser63) is captured by Calsenilin/KCNIP3 (Phospho-Ser63)-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: | calsenilin: a small calcium-binding protein. Member of the family of voltage-gated potassium (Kv) channel-interacting proteins (KCNIPs), which belong to the recoverin branch of the EF-hand superfamily. Modulates K4 voltage-gated potassium channels. May regulate A-type currents, and hence neuronal excitability, in response to changes in intracellular calcium. Also functions as a calcium-regulated transcriptional repressor, and to interact with presenilins. May play a role in the regulation of PSEN2 proteolytic processing. |

| NCBI Summary: | This gene encodes a member of the family of voltage-gated potassium (Kv) channel-interacting proteins, which belong to the recoverin branch of the EF-hand superfamily. Members of this family are small calcium binding proteins containing EF-hand-like domains. They are integral subunit components of native Kv4 channel complexes that may regulate A-type currents, and hence neuronal excitability, in response to changes in intracellular calcium. The encoded protein also functions as a calcium-regulated transcriptional repressor, and interacts with presenilins. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008] |
