Assay Principle
Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.
To assess the linearity of the assay, samples were spiked with high concentrations of human JAG1 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

I am looking for an ELISA kit for the detection of Human Jagged1 in the serum of human patients
I found one product produced by Cusabio, catalog number CSB-EL011927HU.
I would like to know the epitope recognized from the antibodies provided by the kit. Do they recognize the N- or C-terminal region of jagged1?


The kit CSB-EL011927HU can detect jagged-1, which was designed for Extracellular, but the specific recognition area of the antibody is not clear.

Target Background

(From Uniprot)
Ligand for multiple Notch receptors and involved in the mediation of Notch signaling. May be involved in cell-fate decisions during hematopoiesis. Seems to be involved in early and late stages of mammalian cardiovascular development. Inhibits myoblast differentiation. Enhances fibroblast growth factor-induced angiogenesis (in vitro).
