ApoE belongs to a group of proteins that bind reversibly with lipoprotein and play an important role in lipid metabolism. In addition to facilitating solublization of lipids，these proteins help to maintain the structural integrity of lipoproteins，serve as ligands for lipoprotein receptors，and regulate the activity of enzymes involved in lipid metabolism. 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. Defects in ApoE are a cause of hyperlipoproteinemia type III. 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 had significantly lower levels of total cholesterol，low-density lipoprotein cholesterol，and non-high-density lipoprotein cholesterol，as well as increased ApoE levels. ApoE2 is a 34.3 kDa protein containing 300 amino acid residues.
應用類型
Western blot analysis （0.5-4 ug/ml）. However， the optimal conditions should be determined individually. Recombinant human ApoE2 （Cat. # 4760-50） can be used as a positive control.
免疫原
E. coli expressed recombinant human ApoE2
來源宿主
兔
反應性
經檢測驗證，可與人種屬來源的ApoE2蛋白發生免疫反應.
保存建議
