Description
Purified recombinant Human ApoE4 protein
ApoE4 is the high risk variant of the APOE gene, the gene most associated with increased risk for late-onset Alzheimer's disease. Wikipedia shows that it is not a direct determinant of the disease - at least a third of patients with Alzheimer's disease are ApoE4 negative and some ApoE4 homozygotes never develop the disease. Yet those with ApoE4/ApoE4 have ~20x risk of developing Alzheimer's
