|Application ||WB, IHC|
|Calculated MW||36154 Da|
|Other Names||Apolipoprotein E, Apo-E, APOE|
|Target/Specificity||A synthetic peptide corresponding to residues near the N-term of human apolipoprotein E was used as an immunogen.|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Apolipoprotein E Antibody (N-term) is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Mediates the binding, internalization, and catabolism of lipoprotein particles. It can serve as a ligand for the LDL (apo B/E) receptor and for the specific apo-E receptor (chylomicron remnant) of hepatic tissues.|
|Tissue Location||Occurs in all lipoprotein fractions in plasma. It constitutes 10-20% of very low density lipoproteins (VLDL) and 1-2% of high density lipoproteins (HDL). APOE is produced in most organs. Significant quantities are produced in liver, brain, spleen, lung, adrenal, ovary, kidney and muscle|

The apolipoproteins are family of amphipathic lipoproteins that plays a crucial role in lipid metabolism. In particular, apolipoprotein E (apo E) is a major component of high density lipoproteins (HDL) chylomicrons and very low-density lipoprotein (VLDL), which functions to remove excess cholesterol. Apo E mediates lipid metabolism and cholesterol homeostasis by binding to several hepatic lipoprotein receptors, such as low density lipoprotein receptor (LDLR) and the LDLR-related protein (1). Apo E deficiency is linked to hyperlipoproteinemia type III; a genetic disorder characterized by elevated plasma cholesterol and triglyceride levels and accelerated coronary artery disease (2). Three major isoforms of Apo E (E2, E3, E4) has been identified, with E3 being the most common in human. E4 presence has been associated to increase probability of developing late-onset form of Alzheimer disease (3).
