Anti-Mouse CD339 (Jagged 1) Functional Grade Purified

Description: This HMJ1-29 monoclonal antibody reacts with mouse Jagged-1, one of five type I transmembrane proteins that serves as a Notch receptor ligand. Upon binding the Notch receptor (e.g. Notch 1-4), Jagged-1 undergoes proteolytic cleavage, first by ADAM-family metalloproteases and then by gamma-secretase. The second cleavage event releases an intracellular fragment whose biological function remains controversial. Jagged-1 is expressed by thymic lymphoid and stromal cells, as well as macrophages and CD8+CD11c+ dendritic cells in the spleen.

The HMJ1-29 antibody is reported to crossreact to rat.
