  Flow Cytometry - Anti-Mesothelin antibody [EPR19025-42] - BSA and Azide free (ab227810)

  Flow cytometric analysis of HeLa (human epithelial cell line from cervix adenocarcinoma) cell line labeling Mesothelin with Anti-Mesothelin antibody [EPR19025-42] ab196235 at 1/50 dilution (red) compared with a Rabbit IgG, monoclonal [EPR25A] - Isotype Control (Rabbit IgG, monoclonal [EPR25A] - Isotype Control ab172730) (black) and an unlabeled control (cells without incubation with primary antibody and secondary antibody) (blue). Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) ab150077) at 1/2000 dilution was used as the secondary antibody.

  Total viable cells were gated for the image.

  This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (Anti-Mesothelin antibody [EPR19025-42] ab196235).

  Western blot - Anti-Mesothelin antibody [EPR19025-42] - BSA and Azide free (ab227810)

  This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (Anti-Mesothelin antibody [EPR19025-42] ab196235).
  

  False colour image of Western blot: Anti-Mesothelin antibody [EPR19025-42] staining at 1/1000 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (Anti-GAPDH antibody [6C5] - Loading Control ab8245) loading control staining at 1/20000 dilution, shown in red. In Western blot, Anti-Mesothelin antibody [EPR19025-42] ab196235 was shown to bind specifically to Mesothelin. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4°C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776) at 1/20000 dilution.
