The EGFR.1 monoclonal antibody specifically binds to the epidermal growth factor receptor (EGF-R). The EGF-R is a transmembrane glycoprotein of approximately 170 kDa that is expressed on most cells. It consists of a glycosylated extracellular domain which binds to epidermal growth factor (EGF), a transmembrane domain, and an intracellular domain with tyrosine-kinase activity essential for signal transduction. The EGF-R plays an important role in the growth and differentiation of many cellular types. Transforming growth factor α (TGFα), vaccinia virus growth factor, and related growth factors can also bind to and signal through the EGF-R.
The antibody was conjugated to BD Horizon™ BV786 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 786-nm. BD Horizon BV786 can be excited by the violet laser and detected in a filter used to detect Cy™7-like dyes (eg, 780/60-nm filter).
