The ILK Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect ILK protein expression profile in cells. The kit can be used for measuring the relative amounts of ILK in cultured cells as well as screening for the effects that various treatments, inhibitors (ie siRNA or chemicals), or activators have on ILK.
Qualitative determination of ILK concentration is achieved by an indirect ELISA format. In essence, ILK is captured by ILK-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: | ILK: a tyrosine kinase-like kinase of the MLK family. Couples integrins and growth factors to downstream pathways involved in cell survival, cell cycle control, cell-cell adhesion and cell motility. Functions as a scaffold bridging the extra-cellular matrix and growth factor receptors to the actin cytoskeleton through interactions with the ILK-PINCH complex. This complex, which includes integrin, PINCH (which links ILK to receptor tyrosine kinases via Nck2), PARVA and affixin, is considered to be one of the convergence points of integrin- and growth factor-signaling pathways. May be implicated in mediating cell architecture, adhesion to integrin substrates and anchorage-dependent growth in epithelial cells. Stimulated downstream of PI3 kinase. Increased expression is correlated with progression of several tumor types, including breast, prostate, and colon carcinomas. Overexpression drives anchorage-independent growth and faster cell cycle. |

| NCBI Summary: | This gene encodes a protein with a kinase-like domain and four ankyrin-like repeats. The encoded protein associates at the cell membrane with the cytoplasmic domain of beta integrins, where it regulates integrin-mediated signal transduction. Activity of this protein is important in the epithelial to mesenchymal transition, and over-expression of this gene is implicated in tumor growth and metastasis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2013] |
