Application Abreviews Notes 1 Application Abreviews Flow Cyt Notes 1/1000. ab172730-Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody. IP Use at an assay dependent concentration. WB 1/10000 - 1/50000. Predicted molecular weight: 515 kDa.Can be blocked with Human Apolipoprotein B peptide (ab199783). Application notes Is unsuitable for ICC/IF or IHC-P. Target Function Apolipoprotein B is a major protein constituent of chylomicrons (apo B-48), LDL (apo B-100) and VLDL (apo B-100). Apo B-100 functions as a recognition signal for the cellular binding and internalization of LDL particles by the apoB/E receptor. Involvement in disease Hypobetalipoproteinemia, familial, 1 Familial ligand-defective apolipoprotein B-100 Defects in APOB associated with defects in other genes (polygenic) can contribute to hypocholesterolemia. Sequence similarities Contains 1 vitellogenin domain. Post-translational modifications Palmitoylated; structural requirement for proper assembly of the hydrophobic core of the lipoprotein particle. Cellular localization Cytoplasm. Secreted. Anti-Apolipoprotein B antibody [EPR2914] images Overlay histogram showing HepG2 cells stained with ab139401 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab139401, 1/1000 dilution) for 30 min at Flow Cytometry - Anti-Apolipoprotein B antibody 22°C. The secondary antibody used was [EPR2914] (ab139401) Alexa Fluor® 488 goat anti-rabbit IgG (H+L) (ab150077) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (0.1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter. 2 All lanes : Anti-Apolipoprotein B antibody [EPR2914] (ab139401) at 1/10000 dilution Lane 1 : Human plasma lysate Lane 2 : Human serum lysate Lysates/proteins at 10 µg per lane.
