Vimentin is a protein that in humans is encoded by the VIM gene. The gene encoding human vimentin is located on the short arm of chromosome 10. Vimentin is a type III intermediate filament (IF) protein that is expressed in mesenchymal cells. IF proteins are found in all metazoan cells as well as bacteria. IF, along with tubulin-based microtubules and actin-based microfilaments, comprises the cytoskeleton. All IF proteins are expressed in a highly developmentally-regulated fashion; vimentin is the major cytoskeletal component of mesenchymal cells. Because of this, vimentin is often used as a marker of mesenchymally-derived cells or cells undergoing an epithelial-to-mesenchymal transition (EMT) during both normal development and metastatic progression.
VIM Polyclonal Antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen. This antibody has been tested with WB, IHC-p, IF and ELISA. And Abbkine suggested starting dilutions are as follows: WB: 1:500-1:2000, IHC-p: 1:100-1:300, IF: 1:200-1:1000, ELISA: 1:10000.
