  Immunocytochemistry/ Immunofluorescence - Anti-CHMP2B antibody [EPR10807(B)] (ab157208)

  Immunocytochemistry analysis of HepG2 (Human hepatocellular carcinoma epithelial cell) cells labeling CHMP2B with Purified ab157208 at 1:250 dilution (0.6 µg/ml). Cells were fixed in 4% Paraformaldehyde and permeabilized with 0.1% tritonX-100. Cells were counterstained with Alexa Fluor® 594 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) 1:200 (2.5 µg/ml). Goat anti rabbit IgG (Alexa Fluor® 488, Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) ab150077) was used as the secondary antibody at 1:1000 (2 µg/ml) dilution. DAPI (blue) was used as nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.

  Western blot - Anti-CHMP2B antibody [EPR10807(B)] (ab157208)

  Lanes 1 - 4: Merged signal (red and green). Green - ab157208 observed at 45 kDa. Red - loading control, Anti-GAPDH antibody [6C5] - Loading Control ab8245, observed at 38 kDa.
  

  ab157208 was shown to specifically react with CHMP2B in wild-type A549 cells as signal was lost in CHMP2B knockout cells. Wild-type and CHMP2B knockout samples were subjected to SDS-PAGE. The membrane was blocked with 3% Milk. ab157208 and Anti-GAPDH antibody [6C5] - Loading Control ab8245 (Mouse monoclonal [6C5] to GAPDH - Loading Control) were incubated overnight at 4°C at 1/1000 dilution and 1/1000 dilution respectively. Blots were developed with 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 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

  Immunocytochemistry/ Immunofluorescence - Anti-CHMP2B antibody [EPR10807(B)] (ab157208)

  ab157208 was shown to react with CHMP2B in wild-type U2OS cells in immunocytochemistry with loss of signal observed in a CHMP2B knockout cell line. Wild-type and knockout cells were mixed and pelleted at a 1:1 ratio on coverslips. The cells were fixed with 4% paraformaldehyde (15 min) then permeabilized with 0.1% Triton X-100 (10min) and then blocked with 1x PBS, 0.01% Triton X-100, 5% BSA, 5% NGS. The cells were then incubated with ab157208 at dilution overnight at 4°C followed by a further incubation at room temperature for 1h with a goat anti-rabbit secondary antibody to (Alexa Fluor® 555) at 0.5 ?g/ml. Acquisition of the green (wild-type), red (antibody staining) and far-red (knockout) channels was performed. Representative grayscale images of the red channel are shown. Wild-type and knockout cells are outlined with yellow and magenta dashed line, respectively. Schematic representation of the mosaic strategy used is shown on the bottom-right panel. Image was acquired with a Zeiss(LSM-880).

  ab157208 was shown to react with CHMP2B in wild-type U2OS cells in Western blot with loss of signal observed in a CHMP2B knockout cell line. Wild-type U2OS and CHMP2B knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 5% milk in TBST for 1 hr before incubation with ab157208 overnight at 4 °C at a 1/1000 dilution. Blots were incubated with secondary antibodies at 0.2ug/mL before imaging.
