The antibody was purified by affinity chromatography, and conjugated with PE under optimal conditions. The solution is free of unconjugated PE and unconjugated antibody.
CDw119 is a 90-100 kD type I transmembrane protein, also known as IFN-γ R α chain or IFN-γRI. The IFN-γ receptor is a complex of a high affinity IFN-γ-binding chain (aka, IFN-γ R α chain) and a second accessory protein required for signal transduction known as IFN-γ R β chain. The IFN-γ R α chain is a member of the class II cytokine receptor family. Binding of IFN-γ induces receptor dimerization and internalization. Signal transduction involves Jak1 and Jak2 protein kinases and involves STAT1 activation. The IFN-γ receptor is expressed at moderate levels on virtually every cell with the exception of erythrocytes.
