Anti-Apolipoprotein E 抗体 [EP1373Y] (ab51015)

False colour image of Western blot: Anti-Apolipoprotein E antibody [EP1373Y] staining at 1/1000 dilution, shown in green; Mouse anti-Alpha Tubulin [DM1A] (ab7291) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab51015 was shown to bind specifically to Apolipoprotein E. A band was observed at 32-35 kDa in wild-type HepG2 cell lysates with no signal observed at this size in APOE knockout cell line ab280758 (knockout cell lysate ab282991). To generate this image, wild-type and APOE knockout HepG2 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 5 % 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 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human fetal liver tissue labelling Apolipoprotein with unpurified ab51015 at 1/100.

Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.

Immunocytochemistry/Immunofluorescence analysis of HepG2 cells labelling Apolipoprotein E with purified ab51015 at 1/50. Cells were fixed with 4% paraformaldehyde and permeabilized with 0.1% Triton X-100. An Alexa Fluor^® 488-conjugated goat anti-rabbit IgG (1/500) was used as the secondary antibody. DAPI (blue) was used as the nuclear counterstain.

Control: primary antibody (1/100) and secondary antibody, ab150120, an Alexa Fluor^® 594-conjugated goat anti-mouse IgG (1/500).

Intracellular Flow Cytometry analysis of 293T cells labelling Apolipoprotein E with purified ab51015 at 1/20 (red). Cells were fixed with 2% paraformaldehyde. A FITC-conjugated goat anti-rabbit IgG (1/150) was used as the secondary antibody. Black - Isotype control, rabbit monoclonal IgG. Blue - Unlabelled control, cells without incubation with primary and secondary antibodies. 

Blocking buffer and concentration: 5% NFDM/TBST.

Diluting buffer and concentration: 5% NFDM /TBST.

Blocking buffer and concentration: 5% NFDM/TBST.

Diluting buffer and concentration: 5% NFDM /TBST.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human liver tissue labelling Apolipoprotein E with purified ab51015 at 1/100. Heat mediated antigen retrieval was performed using Tris/EDTA buffer pH 9. ab97051, a HRP-conjugated goat anti-rabbit IgG (H+L) was used as the secondary antibody. Negative control using PBS instead of primary antibody. Counterstained with hematoxylin.

ab51015 (purified) at 1/30 immunoprecipitating Apolipoprotein in human fetal liver tissue lysate. For western blotting, a peroxidase-conjugated goat anti-rabbit IgG (H+L) was used as the secondary antibody (1/1000).

Blocking buffer and concentration: 5% NFDM/TBST.

Diluting buffer and concentration: 5% NFDM /TBST.
