A17067B_Pure_APOE_Antibody_1_040518
Western blot of purified anti-APO E, 109-116 antibody (clone A17067B). Lane 1: Molecular weight marker; Lane2: 50 ng of recombinant human Apo E2; Lane 3: 50 ng of recombinant human Apo E3; Lane 4: 50 ng of recombinant human Apo E4; Lane 5: 16 µg of human plasma. The blot was incubated with 0.2 µg/mL of the primary antibody overnight at 4°C, followed by incubation with HRP-labeled goat anti-mouse IgG (Cat. No. 405306). Enhanced chemiluminescence (Cat. No. 426302) was used as the detection system.

    Direct ELISA of purified anti-APO E, 109-116 antibody (clone A17067B) binding to plate-immobilized recombinant human APO E2, APO E3, and APO E4. ELISA was performed by coating wells with 100 ng of APO E proteins. The wells were then incubated with the primary antibody at 37°C for 45 minutes, followed by incubation with horseradish peroxidase labeled goat anti-mouse secondary antibody. TMB (3, 3', 5, 5' tetramethylbenzidine, Cat. No. 421501) was used as the detection system.

Description

Apolipoprotein E (Apo E) belongs to a class of apolipoproteins that mediate the binding, internalization, and catabolism of lipoprotein particles. Apo E is produced by the liver and macrophages in peripheral tissues where it regulates cholesterol metabolism. In the central nervous system, Apo E is primarily produced by astrocytes and plays an important role in transporting cholesterol to neurons via Apo E receptors. Apo E has three alleles (ApoE2, ApoE3 and ApoE4) that differ from each other by only one or two amino acids at positions 112 and 158. ApoE 4 is one of the largest known genetic risk factors for late-onset Alzheimer's disease. Furthermore, Apo E is associated with cardiovascular disease, Lipoprotein Glomerulopathy and Sea-Blue Histiocyte Disease.

Antigen Details

Structure
Human APO E is a 299 amino acid protein with a molecular mass of 32 kD, and exists as 3 major isoforms, APO E2, APO E3, and APO E4.
Distribution

Tissue sources: Ubiquitously expressed. Highest levels in liver, brain, spleen, adrenal gland, and kidney.

Cellular distribution: Plasma membrane, nucleus, endoplasmic reticulum, golgi apparatus, endosome, and extracellular.

Function
Apo E is involved in lipoprotein metabolism as well as the transport of fat-soluble vitamins, and cholesterol. Apo E also forms complexes with amyloid beta peptides leading to its uptake and degradation by microglia.
Interaction
Tau, amyloid beta
Ligand/Receptor
LDL receptor, SORL1
