Protein Jagged-1 ELISA [JAG1]: A Vital Tool in Notch Signaling and Cellular Research

The Protein Jagged-1 ELISA [JAG1] is a high-sensitivity immunoassay designed to quantify Jagged-1 levels in biological samples. This assay is an indispensable tool for researchers investigating Notch signaling, a critical pathway in cell fate determination, organogenesis, and disease pathogenesis.

What is Jagged-1 (JAG1)?

Jagged-1 is a membrane-bound ligand in the Notch signaling pathway, playing an essential role in cell differentiation, proliferation, and apoptosis. Dysregulation of JAG1 expression has been linked to cancers, developmental disorders, and cardiovascular diseases. To explore the molecular function of JAG1, visit the National Center for Biotechnology Information (NCBI) and National Human Genome Research Institute (NHGRI).
