G159 is a chicken polyclonal antibody (IgY) targeting vimentin, the 57 kDa type III intermediate filament protein expressed in mesenchymal and neural cells and upregulated during epithelial-to-mesenchymal transition (EMT). The chicken IgY format eliminates cross-reactivity with mammalian IgG secondary antibodies, enabling multiplexing with rabbit or mouse primary antibodies in the same experiment. Validated for WB, IHC, and ICC/IF in human, mouse, and rat samples.
