The MHJ1-152 monoclonal antibody specifically binds to human Jagged1, a type I transmembrane protein that is one of the ligands for the Notch family of receptors. It is expressed in many fetal and adult tissues including stromal and epithelial cells. JAG1 gene mutations are associated with defects of the heart, liver, kidney and other tissues. Through its interaction with the Notch proteins, Jagged1 affects the development of the hematopoietic system and numerous organs. Jagged1 was assigned the CD339 designation at the 8th International Workshop on Human Leucocyte Differentiation Antigens.
The antibody was conjugated to BD Horizon™ BV711 which is part of the BD Horizon Brilliant™ Violet family of dyes. This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405-nm and an acceptor dye with an Em Max at 711-nm. BD Horizon BV711 can be excited by the violet laser and detected in a filter used to detect Cy™5.5 / Alexa Fluor™ 700-like dyes (eg, 712/20-nm filter). Due to the excitation and emission characteristics of the acceptor dye, there may be moderate spillover into the Alexa Fluor™ 700 and PerCP-Cy5.5 detectors. However, the spillover can be corrected through compensation as with any other dye combination.
