  • Function

    Endocytic receptor involved in endocytosis and in phagocytosis of apoptotic cells. Required for early embryonic development. Involved in cellular lipid homeostasis. Involved in the plasma clearance of chylomicron remnants and activated LRPAP1 (alpha 2-macroglobulin), as well as the local metabolism of complexes between plasminogen activators and their endogenous inhibitors. May modulate cellular events, such as APP metabolism, kinase-dependent intracellular signaling, neuronal calcium signaling as well as neurotransmission.
    Functions as a receptor for Pseudomonas aeruginosa exotoxin A.
  • Tissue specificity

    Most abundant in liver, brain and lung.
  • Sequence similarities

    Belongs to the LDLR family.
    Contains 22 EGF-like domains.
    Contains 31 LDL-receptor class A domains.
    Contains 34 LDL-receptor class B repeats.
  • Post-translational

    Cleaved into a 85 kDa membrane-spanning subunit (LRP-85) and a 515 kDa large extracellular domain (LRP-515) that remains non-covalently associated. Gamma-secretase-dependent cleavage of LRP-85 releases the intracellular domain from the membrane.
    The N-terminus is blocked.
    Phosphorylated on serine and threonine residues.
    Phosphorylated on tyrosine residues upon stimulation with PDGF. Tyrosine phosphorylation promotes interaction with SHC1.
  • Cellular localization

    Cytoplasm. Nucleus. After cleavage, the intracellular domain (LRPICD) is detected both in the cytoplasm and in the nucleus and Cell membrane. Membrane, coated pit.

  • ICC/IF image of ab20384 stained Mcf7 cells. The cells were 100% methanol fixed (5 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 (ab20384, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse 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.

  • ab20384 staining human mesothelial cells by flow cytometry.  Cells were lifted in lifting buffer plus FBS and fixed with formaldehyde.  The cell population was gated against mIgG control.  The primary antibody was diluted 1/100 in 0.2% BSA in PBS and incubated with the sample at a concentration of 1 µg/100 µl for 1 hour at 4°C.  A FITC conjugated goat anti-mouse antibody was used as the secondary, diluted 1/100 and incubated with the sample at a concentration of 1 µg/100 µl.

  • Ab20384 staining primary rat hepatocytes cells by EM. The cells were fixed and prepared by Tokuyasu method. The cryosections of 70nm were placed on 100 mesh grids. All the following steps were done at room temperature. Blocking was carried out for 30 min with 1% fish skin gelatine (FSG). The tissue sections were placed on a drop of 5 ul of first Ab (anti-LRP 8G1) for 20 min at dilutions of 1:400 or 1:600 seemed to work the best. After incubation with the primary antibody, 3. 5 x 2 min wash was done with PBS and the sections were placed on a drop of 5 ul of secondary Ab (goat anti-mouse) for 20 min (dilution 1:150 5. 5 x 2 min wash with PBS). Samples were placed on a drop of 5 ul of PAG10 for 15 min (dilution 1:60 or 1:70) and then 5 x 2 min wash with PBS. 2 min on 1% glutaraldehyde for fixation and 4 x 2.5 min on H2O. afterthat 1 second + 1 second + 6 min on drops of Methyl Cellulose/Uranyl Acetate (9:1) on ice.

Thank you for taking the time to provide the further information.

The details you have kindly provided will provide us with vital information for our monitoring of product quality

I appreciate the time the customer has spent in the laboratory and understand your concerns. It is regrettable the results have not been successful. Reviewing the details, I am sorry there are no further tips to provide on this occasion to help improve the results. I can suggest you have regrettably received a bad vial. I apologize for the inconvenience.

I have also spoken to our distributors team and I am happy to let you know we are prepared to make an exception and continue to provide our Abpromise for Symbios customers. Therefore, I am pleased to offer you a free of charge replacement or credit note in compensation for this case.

In addition, I can suggest the customer may like to consider the following suggestions as a check for future experiments:

1. I can suggest to try adding 0.2% Tween to the antibody dilution buffer and wash buffer. This will help to solubilise the antibody and keep the cells permeabilised.

2. I can recommend to try wash steps: 3 X 5 minutes in PBS containing 0.2% Tween.

3. We recommend to incubate at 4oC overnight with antibodies. This can often provide more efficient and specific staining.

4. Is the current vial of secondary antibody working well with other primary antibodies?

I hope this will be helpful. I look forward to hearing from you with details of how you would like to proceed.

Thank you for contacting us.

For ab20384, the lab recommends using human umbilical vein endothelial cells (HUVEC) as a negative control. If you do not have access to this type of cells, according to the human protein atlas (linked below),Low Density LRP is not expressed in tonsil, skin, or breast tissues, so any of these could be used as a negative control. If you are looking for lysates, you could try ab30090, ab30166, or ab29614 and forslides, you could try ab4365.

I hope this helps, please let me know if you need any additional information.
