Recombinant Anti-PDHA1 antibody [EPR11098] (ab168379)

Lanes 1 - 3: Merged signal (red and green). Green - ab168379 observed at 43 kDa. Red - loading control, ab130007, observed at 130 kDa.

ab168379 was shown to recognize PDHA1 in wild-type HeLa cells as signal was lost at the expected MW in PDHA1 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and PDHA1 knockout samples were subjected to SDS-PAGE. Ab168379 and ab130007 (Mouse anti Vinculin loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

Blocking and diluting buffer: 5% NFDM/TBST

Immunocytochemistry/ Immunofluorescence analysis of HT-29 (Human colorectal adenocarcinoma epithelial cell) cells labeling PDHA1 with Purified ab168379 at 1:100 dilution (3.5 μg/ml). Cells were fixed in 4% Paraformaldehyde and permeabilized with 0.1% tritonX-100. Cells were counterstained with Ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor^® 594) 1:200 (2.5 μg/ml). ab150077 Goat anti rabbit IgG (Alexa Fluor^® 488) was used as the secondary antibody at 1:1000 dilution. DAPI nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.

Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
