The EMab-134 monoclonal antibody specifically recognizes 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 epitope recognized by EMab-134 is an extracellular peptide that is not affected by glycosylation. 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™ BV510 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 405-nm and Em Max at 510-nm, BD Horizon BV510 can be excited by the violet laser and detected in the BD Horizon V500 (525/50-nm) filter set. BD Horizon BV510 conjugates are useful for the detection of dim markers off the violet laser.
