    Cytokeratins, a group comprising at least 29 different proteins, are characteristic of epithelial and trichocytic cells. Cytokeratins 1, 4, 5, 6, and 8 are members of the type II neutral to basic subfamily. Monoclonal anti cytokeratins are specific markers of epithelial cell differentiation and have been widely used as tools in tumor identification and classification. Monoclonal Anti Pan Cytokeratin (mixture) is a broadly reactive reagent, which recognizes epitopes present in most human epithelial tissues. It facilitates typing of normal, metaplastic and neoplastic cells. Synergy between the various components results in staining amplification. This enables identification of cells, which would otherwise be stained only marginally. The mixture may aid in the discrimination of carcinomas and nonepithelial tumors such as sarcomas, lymphomas and neural tumors. It is also useful in detecting micrometastases in lymph nodes, bone marrow and other tissues and for determining the origin of poorly differentiated tumors. There are two types of cytokeratins the acidic type I cytokeratins and the basic or neutral type II cytokeratins. Cytokeratins are usually found in pairs comprising a type I cytokeratin and a type II cytokeratin. Usually the type II cytokeratins are 8kD larger than their type I counterparts.

  • Imaging Mass Cytometry™ (IMC™) image of human lung cancer tissue stained with Anti-pan Cytokeratin antibody [AE1/AE3]. ab80826 (carrier-free antibody, purified) was metal-conjugated using a Maxpar® Antibody Labeling Kit from Fluidigm. Immunostaining was performed according to Fluidigm’s protocols. Briefly, slides were subject to deparaffinization and heat-induced epitope retrieval, followed by overnight incubation at 4°C with an antibody cocktail containing metal-tagged antibodies in blocking buffer. Slides were subsequently washed with 0.2% Triton-X and 1x PBS, counterstained with Cell-ID™ Intercalator-Ir diluted at 1/400 in 1x PBS for 30 min at room temperature, rinsed for 5 min with distilled H2O, and air-dried prior to IMC™ acquisition. IMC™ acquisition was performed using the Fluidigm Hyperion™ Imaging System.

  • Immunohistochemical analysis of formalin-fixed, paraffin-embedded human tonsil tissue with ab80826 at 1/400 dilution. Anti-Mouse HRP polymer was used as the secondary detection system. Heat-mediated antigen retrieval was performed using citrate based pH 6.0 buffer.

    This image was generated using the ascites version of the product.

  • ICC/IF image of ab80826 stained HepG2 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab80826, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96879, DyLight® 488 goat anti-mouse IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

    This image was generated using the ascites version of the product.

  • Overlay histogram showing A431 cells stained with ab80826 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab80826, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.

  • Immunohistochemical analysis of rat bladder tissue, labeling pan Cytokeratin with ab80826. Samples were formaldehyde fixed, heat mediated antigen retrieval was perfmormed with 10mM citrate buffer, and blocking was with 10% serum for 2 hours at 23°C. Incubation with ab80826 (diluted 1/1000) was for 17 hours at 4°C.

Merci de nous avoir contactés.

L'anticorps prédilué ab82612 (Anti-Cytokeratin [MNF116]) a une concentration entre 1 et 3 µg/ml.
L'anticorps ab28028 (Anti-Vimentin [Vim 3B4]) est un supernageant, la concentration en anticorps ne peut donc pas être déterminée précisement mais elle est estimée entre 1 et 3 mg/ml.
Malheureusement le laboratoire qui produit l'anticorps ab961 (Anti-pan Cytokeratin antibody [AE1+AE3]) ne désire pas communiquer la concentration de ce produit. Nous sommes désolés de ne pas pouvoir vous fournir cette information, sachez cependant que nous avons au catalogue une référence équivalente, non-prédiluée, ab80826, à 1 mg/ml, https://www.abcam.com/ab80826.

J'espère que ces informations vous seront utiles. N'hésitez pas à nous contacter de nouveau si vous avez d'autres questions.
