Notch proteins (so named for 'notches' in fly wings) are type I transmembrane glycoproteins involved in specifying cell fates and defining boundaries between different cell types during developmental processes. Notch extracellular domains are large, having 34-36 EGF-like repeats followed by three notch/Lin-12 repeats. Notch proteins interact with transmembrane ligands Jagged, Delta, and Serrate expressed on the surface of a neighboring cell. Upon ligand binding, a series of cleavage events results in the release of the Notch intracellular domain (NICD), which translocates to the nucleus and initiates transcription of Notch-responsive genes. Thus, Notch acts as both a ligand-binding receptor and a nuclear factor that regulates transcription.
The four mammalian Notch receptors appear to have distinct functions, since they do not compensate for one another in genetic studies. Mutations in Notch receptors also lead to specific developmental disorders. For example, Notch-3 is predominantly expressed in the developing central nervous system of mice. Mutations in Notch-3 in humans cause an autosomal dominant condition called CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy). This disorder is characterized by recurrent ischemic strokes at an early age without any underlying vascular risk and progressive dementia.

What is the difference between the Quantikine and Duoset ELISA kits?
Our Quantikine kits are fully optimized and validated for the sample types listed on the product specific webpage and datasheet, as this can vary between kits. Each kit is supplied ready to use with one pre-coated 96-well plate, a detection antibody directly conjugated to HRP, and all other necessary reagents. These kits are ideal for researchers who want the convenience of a ready to use and optimized ELISA product. Some of these kits are also available prepackaged in larger 6 and 50 plate sizes.Our DuoSet Kits, in contrast, are ELISA development kits containing the capture and detection antibody, the mass-value calibrated standard, and streptavidin-HRP to prepare approximately 5 or 15 plates. Ancillary reagents will need to be used/purchased, and for most kits, we will recommend one of our Ancillary Reagent Kits, which contain the reagents we use ourselves in-house. DuoSet kits are validated only for cell culture supernatant samples and therefore require further development and validation for accurate measurement in more complex samples such as serum and plasma. Our DuoSet Kits offer an economical, flexible alternative for the experienced ELISA user.
Notch1 - A multifunctional transmembrane receptor Notch1 is a member of the Notch family of Type 1 single-pass transmembrane proteins that share an extracellular domain of multiple epidermal growth factor-like (EGF) repeats. Notch family members play key roles in a variety of developmental process... Read full blog post.
