Human APOE/Apolipoprotein E Protein

Product Info

Recombinant Human APOE/Apolipoprotein E Protein is expressed from Expi293 with His tag at the N-terminal. It contains Lys19-His317.[Accession | P02649-1]

Molecular Weight

The protein has a predicted MW of 35.3 kDa. Due to glycosylation, the protein migrates to 35-40 kDa based on Tris-Bis PAGE result.


Less than 1EU per μg by the LAL method.


> 95% as determined by Tris-Bis PAGE


Supplied as 0.22μm filtered solution in PBS (pH 7.4).


The product should be stored at -70℃. Please do not repeated freeze-thaw cycles.

Assay Data
Tris-Bis PAGE

Human Apolipoprotein E on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.


Apolipoprotein E (apoE) is a lipid carrier in both the peripheral and the central nervous systems. Lipid-loaded apoE lipoprotein particles bind to several cell surface receptors to support membrane homeostasis and injury repair in the brain. Considering prevalence and relative risk magnitude, the ε4 allele of the APOE gene is the strongest genetic risk factor for late-onset Alzheimer's disease (AD).
