Vimentin is found in all types of sarcomas and lymphomas. Positive staining for vimentin is seen in most cells of fibrosarcomas, liposarcomas, malignant fibrous histocytomas, angiosarcomas, chondrosarcomas and lymphomas. All melanomas and Schwannomas are strongly vimentin-positive.

2021-03-16 · Under strain, alpha-helices in vimentin Intermediate filaments (IFs) might unfold to beta-sheets. Upon repeated stretching, the filaments soften; however, the remaining plastic strain is negligible. Vimentin IFs do not recover their original stiffness on reasonable time scales, and these seemingly contradicting results are explained by introducing a third, less well-defined conformational state.

Differentiation of cell types or structures is not the Microscopy stains enhance the visualization of cells and cell parts under a light microscope.

Vimentin Antibody Staining Protocol for Immunohistochemistry Description: This monoclonal antibody reacts with the intermediate filament protein vimentin present in cells of mesenchymal origin. Broad interspecies cross-reactivity has been observed with human, rat, and chicken vimentin. OMA1-06001 detects vimentin from mouse, rat, hamster, chicken, goat, canine, monkey, zebrafish, porcine and human tissues and cells. OMA1-06001 has been successfully used in Western blot, immunofluorescence, immunocytochemistry, flow cytometry, and immunohistochemistry (frozen) procedures. Vimentin Antibody Staining Protocol for Immunohistochemistry . Description: Vimentin is an intermediate filament that is ubiquitously expressed in mesenchymal cells such as fibroblasts, smooth muscle cells, and endothelium. Vimentin is useful as part of an antibody panel for differential diagnostic purposes, such as differentiating soft tissue Using immunologic methods, vimentin can be readily demonstrated in frozen sections as well as paraffin sections.

Tested in Immunofluorescence (IF), Immunocytochemistry (ICC), Immunohistochemistry (Frozen) (IHC (F)) and Immunohistochemistry (Paraffin) (IHC (P)) applications. This antibody reacts with Canine, Chicken, Human, Rat samples. Supplied as 100 µg purified antibody (0.5 mg/mL). 2021-03-16 Immunohistochemical staining for Vimentin is also characteristic of sarcomas (of neural, muscle and fibroblast origin) compared to carcinomas which are generally negative. Melanomas, lymphomas and vascular tumors may all stain for Vimentin.

BioTracker TiY Vimentin is a live cell fluorescent dye that selectively stains TICs over differentiated tumor cells or normal cells. TiY can be used for visualization and enrichment of functionally active TICs from patient tumors.

In contrast, the cutoff value of Vimentin was >2 as high-staining group ( n = 140) and <2 as low-staining group ( n = 68). Immunohistochemically, 239 poorly differentiated adenocarcinomas with solid components of the stomach were stained for vimentin. Vimentin‐positive cases were also stained by CAM 5.2 using serial mirror sections. We found 15 (6.3%) vimentin‐positive cases.

2014-07-15 · Vimentin polymer networks in solution increase their shear elastic modulus at least 30-fold in response to strain, with no accompanying loss of elasticity at strains up to more than 100%, which starkly contrasts the more brittle actin and tubulin-based networks that rupture under significantly less strain . For vimentin stain, I add in a permeabilization step here with 0.3% Triton X-100 in TBS-T at RT for 30 min Rinse 2x 5 min with TBS-T + 0.025% Triton X-100 Block with TBS-T + 3% BSA + 1% serum (of 2016-02-15 · Vimentin is downregulated by Mycobacterium tuberculosis. THP1- derived macrophages were infected with live or heat killed Mycobacterium tuberculosis H37Rv, a virulent laboratory strain, in the Furthermore, vimentin expression, normally observed in mesenchymal cells, has been found to be strongly associated with tumor invasion and metastasis in several cancers. 15 Although a few small studies have investigated the expression of vimentin in NPC cell lines, 16, 17 little is known about the expression and prognostic effect of vimentin on NPC samples. Although no chRCC stained for vimentin, the lack of vimentin expression was not specific for chRCC since 60.9% of ccRCC also failed to express vimentin. Combining the two stains such that only CD9 positive and vimentin negative samples were identified as chRCC improved predictive value only marginally, yielding 100.0% sensitivity and 95.2% specificity.

We retrospectively reviewed the pathology archives in our institution for all specimens with vimentin stain between 2000 and 2016. The cases were classified into epithelial, hematolymphoid, melanocytic, mesenchymal, and unclassified groups, and the staining results were categorized as positive, negative, or unknown, based on the pathology report. CD99, a marker for MIC-2, reacts with normal Sertoli cells and granulosa cells. We investigated CD99 expression in the development of normal ovary and testis as well as in 25 sex cord-stromal tumors (SC-STs), 7 epithelial neoplasms, and 6 germ cell tumors. 2021-03-16 · Under strain, alpha-helices in vimentin Intermediate filaments (IFs) might unfold to beta-sheets.
