The Caspase-3 Colorimetric Cell-Based ELISA Kit offered by Assay Genie is a powerful tool for the precise measurement of caspase-3 levels in cell lysates. This kit is specifically designed for use in cell-based systems, offering researchers a reliable and efficient method for studying apoptosis and cell death mechanisms.Caspase-3 is a key player in the apoptotic pathway, responsible for executing cell death processes in response to various stimuli. Dysregulation of caspase-3 activity has been implicated in numerous diseases, including cancer, neurodegenerative disorders, and autoimmune conditions, highlighting the importance of studying its expression and activation levels.

With high sensitivity and specificity, the Caspase-3 Colorimetric Cell-Based ELISA Kit provides accurate and reproducible results, enabling researchers to gain valuable insights into cell death mechanisms and potential therapeutic targets. This kit is essential for any study focusing on apoptosis and caspase-3 biology, making it a valuable addition to any research laboratory.

The Caspase 3 Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect Caspase 3 protein expression profile in cells. The kit can be used for measuring the relative amounts of Caspase 3 in cultured cells as well as screening for the effects that various treatments, inhibitors (ie siRNA or chemicals), or activators have on Caspase 3.

Qualitative determination of Caspase 3 concentration is achieved by an indirect ELISA format. In essence, Caspase 3 is captured by Caspase 3-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.
Database Information:Gene ID: 836, UniProt ID: P42574, OMIM: 600636, Unigene: Hs.141125
Gene Symbol:CASP3
Sub Type:None
UniProt Protein Function:CASP3: Involved in the activation cascade of caspases responsible for apoptosis execution. At the onset of apoptosis it proteolytically cleaves poly(ADP-ribose) polymerase (PARP) at a '216-Asp-|-Gly-217' bond. Cleaves and activates sterol regulatory element binding proteins (SREBPs) between the basic helix-loop- helix leucine zipper domain and the membrane attachment domain. Cleaves and activates caspase-6, -7 and -9. Involved in the cleavage of huntingtin. Triggers cell adhesion in sympathetic neurons through RET cleavage. Heterotetramer that consists of two anti-parallel arranged heterodimers, each one formed by a 17 kDa (p17) and a 12 kDa (p12) subunit. Interacts with BIRC6/bruce. Highly expressed in lung, spleen, heart, liver and kidney. Moderate levels in brain and skeletal muscle, and low in testis. Also found in many cell lines, highest expression in cells of the immune system. Inhibited by isatin sulfonamides. Belongs to the peptidase C14A family.

NCBI Summary:This gene encodes a protein which is a member of the cysteine-aspartic acid protease (caspase) family. Sequential activation of caspases plays a central role in the execution-phase of cell apoptosis. Caspases exist as inactive proenzymes which undergo proteolytic processing at conserved aspartic residues to produce two subunits, large and small, that dimerize to form the active enzyme. This protein cleaves and activates caspases 6, 7 and 9, and the protein itself is processed by caspases 8, 9 and 10. It is the predominant caspase involved in the cleavage of amyloid-beta 4A precursor protein, which is associated with neuronal death in Alzheimer's disease. Alternative splicing of this gene results in two transcript variants that encode the same protein. [provided by RefSeq, Jul 2008]
