Description
TIMP3 Colorimetric Cell-Based ELISA Kit
The TIMP3 Colorimetric Cell-Based ELISA Kit by Assay Genie is specifically designed for the accurate detection of Tissue Inhibitor of Metalloproteinase 3 (TIMP3) levels in various biological samples. This kit offers high sensitivity and specificity, ensuring precise and reliable results for researchers in a wide range of fields.TIMP3 is a crucial protein that plays a key role in regulating the extracellular matrix and inhibiting the activity of matrix metalloproteinases (MMPs), which are involved in tissue remodeling and degradation. Dysregulation of TIMP3 has been linked to various diseases such as cancer, cardiovascular disorders, and inflammatory conditions, making it an important biomarker for understanding these pathological processes.
With the TIMP3 Colorimetric Cell-Based ELISA Kit, researchers can accurately measure TIMP3 levels in cell culture supernatants, serum, and plasma samples, providing valuable insights into the role of TIMP3 in various physiological and pathological processes.

The TIMP3 Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect TIMP3 protein expression profile in cells. The kit can be used for measuring the relative amounts of TIMP3 in cultured cells as well as screening for the effects that various treatments, inhibitors (ie siRNA or chemicals), or activators have on TIMP3.
Qualitative determination of TIMP3 concentration is achieved by an indirect ELISA format. In essence, TIMP3 is captured by TIMP3-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. |

| NCBI Summary: | This gene belongs to the TIMP gene family. The proteins encoded by this gene family are inhibitors of the matrix metalloproteinases, a group of peptidases involved in degradation of the extracellular matrix (ECM). Expression of this gene is induced in response to mitogenic stimulation and this netrin domain-containing protein is localized to the ECM. Mutations in this gene have been associated with the autosomal dominant disorder Sorsby's fundus dystrophy. [provided by RefSeq, Jul 2008] |
