  Immunocytochemistry/ Immunofluorescence - Anti-Cytokeratin 5 antibody [EPR1600Y] (ab75869)

  Immunocytochemistry/Immunofluorescence analysis of A431 (human epidermoid carcinoma) cells labelling Cytokeratin 5 with purified ab75869 at 1/100. Cells were fixed with 4% Paraformaldehyde and permeabilized with 0.1% Triton X-100. Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) ab150077, Alexa Fluor^® 488-conjugated goat anti-rabbit IgG (1/1000) was used as the secondary antibody. The cells were co-stained with Anti-alpha Tubulin antibody [DM1A] - Loading Control ab7291, a mouse anti-tubulin antibody (1/1000) using Goat Anti-Mouse IgG H&L (Alexa Fluor® 594) preadsorbed ab150120, an Alexa Fluor^® 594-conjugated goat anti-mouse IgG (1/1000) as the secondary. Nuclei couterstained with DAPI (blue).
  

  For negative control 1, rabbit primary antibody was used, followed by anti-mouse secondary antibody (Goat Anti-Mouse IgG H&L (Alexa Fluor® 594) preadsorbed ab150120). For negative control 2, mouse primary antibody (Anti-alpha Tubulin antibody [DM1A] - Loading Control ab7291) was used followed by anti-rabbit secondary antibody (Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) ab150077).

  Flow Cytometry (Intracellular) - Anti-Cytokeratin 5 antibody [EPR1600Y] (ab75869)

  Intracellular Flow Cytometry analysis of A431 (human epidermoid carcinoma) cells labeling Cytokeratin 5 with purified ab75869 at 1/20 dilution (10ug/ml) (red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. A Goat anti rabbit IgG (Alexa Fluor^® 488) (1/2000 dilution) was used as the secondary antibody. Rabbit monoclonal IgG (Black) was used as the isotype control, cells without incubation with primary antibody and secondary antibody (Blue) was used as the unlabeled control.

  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Cytokeratin 5 antibody [EPR1600Y] (ab75869)

  Immunohistochemical analysis of paraffin embedded human tonsil tissue section labelling Cytokeratin 5 with purified ab75869 at dilution of 1/1000. The secondary antibody used was HRP-conjugated Goat Anti-Rabbit IgG H&L (Goat Anti-Rabbit IgG H&L (HRP) ab97051) at dilution of 1/500. The sample was counter-stained with hematoxylin. Antigen retrieval was perfomed using Tris-EDTA buffer, pH 9.0. PBS was used instead of the primary antibody as the negative control and is shown in the inset.

  OI-RD Scanning - Anti-Cytokeratin 5 antibody [EPR1600Y] (ab75869)

  We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen), of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody.
  Based on the comparison with published literature values for mouse monoclonal antibodies, Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.

  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Cytokeratin 5 antibody [EPR1600Y] (ab75869)

  IHC image of Cytokeratin 5 staining in a section of formalin-fixed paraffin-embedded normal human cervix* performed on a Leica Biosystems BOND® RX instrument. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab78569, 0.1ug/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset secondary-only control image is taken from an identical assay without primary antibody.
  For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
