Description: The V9 monoclonal antibody recognizes human Vimentin, a 57 kDa protein that functions as a structural component of intermediate filaments. Vimentin is expressed in cells derived from the mesenchyme but also in specific populations such as radial glia and immature glial cells, as well as pancreatic precursor cells. It is proposed to be a marker of cardiac differentiation. In neural cells, vimentin expression is gradually replaced by neurofilaments. Reports have also shown surface expression of vimentin on activated macrophages, plaets, as well as apoptotic T cells and neutrophils.

This antibody also recognizes canine （dog）, rat and chicken vimentin but does not recognize mouse vimentin.
