Recombinant Human ApoE4

• Cat.No.: ApoE4-3563H
• Product Overview: ApoE4

Specification

• Description: Purified recombinant Human ApoE4 proteinApoE4 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.
