Application

Anti-LDL Receptor, clone 2N19 ZooMAb , Cat. No. ZRB1176, is a highly specific rabbit recombinant monoclonal antibody that targets Low-Density Lipoprotein Receptor and has been tested for use in Flow Cytometry, Immunocytochemistry, Immunohistochemistry, and Western Blotting.
Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected LDL Receptor in RAW264.7 and HEPG2 cell lysates.

Immunohistochemistry (Paraffin) Analysis: A 1:100-1,000 dilution from a representative lot detected LDL Receptor in human liver and rat liver tissue sections.

Immunocytochemistry Analysis: A 1:100 dilution of from a representative lot detected LDL Receptor in A431, HepG2, NIH 3T3 cells.

Flow Cytometry Analysis: 0.1 μg from a representative lot detected LDL Receptor in HepG2.

Note: Actual optimal working dilutions must be determined by the end user as specimens and experimental conditions may vary.

Target description

Low-density lipoprotein receptor (UniProt P01130; also known as LDL receptor) is encoded by the LDLR (also known as FH, FHC) gene (Gene ID: 3949) in human. LDL receptor is a single-pass type I membrane protein that is rapidly endocytosed upon ligand binding. It binds low density lipoprotein (LDL) and transports it into cells by endocytosis. LDL receptor recognizes the apoprotein B100 embedded in the outer phospholipid layer of cholesterol-rich LDL particles and mediates their removal by endocytosis via clathrin-coated pits. It also recognizes the ApoE protein found in chylomicron remnants and VLDL remnants (IDL). LDL receptor is synthesized with a signal peptide (aa 1-21), which is subsequently cleaved off to generate the mature form. The mature form of LDL receptor contains an extracellular domain (aa 22-788), a transmembrane domain (aa 789-810), and a cytoplasmic domain (aa 811-860). The extracellular region contains seven class A (aa 25-313) and six class B (aa 397-658) LDLR repeats and three EGF-like domains (aa 314-353, 354-393, 663-712). LDL-A repeats are known to mediate LDL binding, and repeats 2-7 are required for ApoB binding, while only repeat 5 is required for ApoE binding. The class B (LDL-B) repeats region adopts a beta-propeller conformation and is believed to be responsible for the pH-dependent release of LDL in the endosome. The cytoplasmic tail contains a signal sequence that is important for localizing the receptors to clathrin-coated pits and for triggering receptor-mediated endocytosis upon LDL binding. Mutations in LDLR gene are known to cause familial hypercholesterolemia (FH) leading to high levels of serum LDL and excess deposition of cholesterol in tissues leading to atherosclerosis and higher risk of premature coronary heart disease. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose. Normal appearance is a coarse or translucent resin. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

Reconstitution

30 μg/mL after reconstitution at 25 μL. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
