Allgemeine Beschreibung

Apolipoprotein E (ApoE) belongs to a group of proteins that bind reversibly with lipoproteins. Significant quantities of ApoE are produced in liver and brain and to some extent in almost every organ. ApoE is an important constituent of all plasma lipoproteins. ApoE exists in three major isoforms; E2, E3, and E4, which differ from one another by a single amino-acid substitution. Compared with E3 and E4, E2 exhibits the lowest receptor binding affinity. E2 allele carriers have significantly lower levels of total cholesterol, low-density lipoprotein cholesterol, and non-high-density lipoprotein cholesterol, as well as increased ApoE levels. The gene encoding this protein is localized on human chromosome 19q13.32.

Immunogen

Recombinant fragment corresponding to a region within amino acids 1 and 129 of Apo E (Uniprot ID#P02649)

Anwendung

Suggested starting dilutions are as follows: ICC/IF: 1:100-1:1000, IHC-P: 1:100-1:1000, WB: 1:500-1:3000. Not yet tested in other applications. Optimal working dilutions should be determined experimentally by the end user.

Biochem./physiol. Wirkung

In addition to facilitating solubilization of lipids, apolipoproteins help to maintain the structural integrity of lipoproteins, serve as ligands for lipoprotein receptors, and regulate the activity of enzymes involved in lipid metabolism. Apolipoprotein E (ApoE) plays an important role in lipid metabolism. It′s interaction with specific ApoE receptor enables uptake of chylomicron remnants by liver cells, which is an essential step during normal lipid metabolism. It also binds with the LDL receptor (Apo B/E). Defects in ApoE are a cause of hyperlipoproteinemia type III.

Alzheimer's disease (AD) is the most common neurodegenerative dementia, for which the molecular origins, genetic predisposition and therapeutic approach are still debated. In the 1980s, cells from AD patients were reported to be sensitive to ionizing radiation. In order to

The common APOE2 gene variant is neuroprotective against Alzheimer's disease (AD) and reduces risk by nearly 50%. However, the mechanisms by which APOE2 confers neuroprotection are largely unknown. Here we showed that ApoE protein abundance in human postmortem cortex follows
