Product Specifications

Immunogen

Full length recombinant human Vimentin Antibody expressed in and purified from E. coli. [UniProt# P08670]

Epitope

amino acids 409-425 of human Vimentin (UniProt Accession P08670): SRISLPLPNFSSLNREL

Reactivity Notes

Clones 2D1 (NBP1-92687) and 2A52 (NBP1-92688) both failed to detect the target in mouse tissues although they work well on human and rat samples. This allowed us to firmly map the epitope for both antibodies to the peptide SRISLPLPNFSSLNREL, amino acids 409-425 of the human sequence. This peptide is located at the beginning of the non-helical "tail" region of the molecule and the peptide is totally conserved between human and rat and in most mammalian species, including cow, pig, horse, camel, and many monkeys. Interestingly mouse has the peptide SRISLPLPTFSSLNREL divergent by one amino acid, and neither clones bind this peptide. As a result these antibodies can be used to identify human or rat cells in mouse cultures or tissues and may work with other species that also contain this peptide.

Background: Vimentin

Vimentin is a type III intermediate filament (IF) protein, encoded by the VIM gene, that plays an essential role in cytoskeletal function and is largely expressed by mesenchymal cell such as endothelial cells, fibroblasts, and immune cells (1). Human vimentin monomer protein is 466 amino acids (aa) in length with a theoretical molecular weight of ~54 kDa (2). Vimentin protein contains a central rod domain composed of four alpha-helices which is flanked by an N-terminal head domain and C-terminal tail domain (1,3). Vimentin monomers dimerize to form more complex structures resulting in the assembly of eight tetramers, referred to as unit-length filaments, which then assemble into full-length intermediate filaments that are 10-12 nm wide (1,3,4).

Activated macrophages have been shown to secrete phosphorylated vimentin which can be stimulated by a variety of pathophysiological factors including oxidized low-density lipoproteins and TNF-alpha or inhibited by IL-10 (1). The vimentin protein is often expressed at the cell surface playing a role in cell-cell interactions, tissue damage and repair, immune response, and pathogen recognition (1). Vimentin functions in many cytoskeletal processes including cell migration, which is highlighted by its upregulation during epithelial-to-mesenchymal transition (EMT) (4,5). Vimentin is a commonly used marker for EMT and is expressed by many tumor types (5). For example, high metastasis of oral squamous cell carcinomas also showed high vimentin positive expression in immunohistochemical staining analysis (5). A number of vimentin targeting compounds are in cancer-related clinical trials, however, given the multifunctional role of vimentin, the effect of inhibition on non-malignant cells needs to be thoroughly examined (5).
