Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Description

The antibody is shipped at ambient temperature and may be stored at 4C. For prolonged storage prepare appropriate aliquots and store at or below -20C. Prior to use, an aliquot is thawed slowly in the dark at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at 4C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance or the concentration of the product.

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).
