Our Abpromise guarantee covers the use of ab30532 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Flow Cyt Use at an assay dependent concentration.

ab171870 - Rabbit polyclonal IgG, is suitable for use as an isotype control with this antibody.


IHC-Fr Use at an assay dependent concentration. Used at a dilution of 1/200 for 1 hr on mouse aortic root (see Abreview for further details).
IHC-P 1/400.
WB 1/200. Predicted molecular weight: 95 kDa.

The protein is highly glycosylated through N- and O-linkages and thus migrates at 100 kDa to 160 kDa on SDS-PAGE.

ICC/IF 1/100 - 1/400.


  • Function
    Binds LDL, the major cholesterol-carrying lipoprotein of plasma, and transports it into cells by endocytosis. In order to be internalized, the receptor-ligand complexes must first cluster into clathrin-coated pits. In case of HIV-1 infection, functions as a receptor for extracellular Tat in neurons, mediating its internalization in uninfected cells.
  • Involvement in disease
    Defects in LDLR are the cause of familial hypercholesterolemia (FH) [MIM:143890]; a common autosomal semi-dominant disease that affects about 1 in 500 individuals. The receptor defect impairs the catabolism of LDL, and the resultant elevation in plasma LDL-cholesterol promotes deposition of cholesterol in the skin (xanthelasma), tendons (xanthomas), and coronary arteries (atherosclerosis).
  • Sequence similarities
    Belongs to the LDLR family.
    Contains 3 EGF-like domains.
    Contains 7 LDL-receptor class A domains.
    Contains 6 LDL-receptor class B repeats.
  • Post-translational
    N- and O-glycosylated.
    Ubiquitinated by MYLIP leading to degradation.
  • Cellular localization
    Cell membrane. Endomembrane system. Membrane > clathrin-coated pit. Found distributed from the plasma membrane to intracellular compartments.

  • ab30532 staining LDL receptor in human lung parenchyma.
    Left panel: with primary antibody at 1/400. Right panel: isotype control.
    Sections were stained using an automated system (DAKO Autostainer Plus), at room temperature: sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffers citrate pH6.1. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.

  • ICC/IF image of ab30532 stained HepG2 cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab30532, 1/400) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
