anti-Vimentin, VIM 3B4 + positive western blot control
The set contains enough Western blot control to perform 5 Western blots.
The anti-Vimentin, VIM 3B4 antibody is an excellent marker for mesenchymal cells and mesenchyme-derived tumors (sarcoma, lymphoma, melanoma). The antibody is highly specific for the intermediate filament protein vimentin present in all cells of mesenchymal origin.

The antibody is highly specific for the intermediate filament protein vimentin which is present in all cells of mesenchymal origin. VIM 3B4 has turned out to be the most avid mab to vimentin.
Polypeptide reacting: Mr 57 000 intermediate filament protein (vimentin) of mesenchymal cells.
Tumors specifically detected: sarcoma (including myosarcoma), lymphoma, melanoma.
The binding region of monoclonal antibody VIM3B4 has been characterized by Bohn et al.(1992). According to these authors, the epitope has been localized on the alpha-helical part of vimentin (rod domain coil 2). Due to an aa substitution at position of aa 353 in murine vimentin (that could explain for the weak cross-reaction of the antibody with murine vimentin) they were able to narrow down the binding region around position 353. These findings were confirmed by truncation mutagenesis experiments using human vimentin (Rogers et al., 1995).

Positive western blot control:
Whole Cell Lysate from SV80 Human Lung fibroblast (SV40-transformed) as positive western blot control.
SV80 whole cell lysate was prepared by homogenization in PBS containing Pefablock.
Protein concentration was determined using Bradford assay.

Most of our liquid antibodies and reconstituted lyophilized antibodies may be stored for short term storage (up to 3 month) at 2-8°C. For long term storage we recommend to store the antibody at -20°C in aliquots. Please avoid freeze and thaw cycles.
Most of our conjugated antibodies should be stored at 2-8°C.
The individual storage conditions are mentioned on the datasheet.
