Use: The antibody can be used for detection of apo E in plasma and lipoproteins, immunoassays, immunoblots, enzyme conjugation, or biotinylation.
Storage: -20°C for long-term storage, 4°C for short- term storage. Aliquot to avoid repeated freezing and thawing.
Form: Freeze dried powder
Stabilizer: 10 mg / ml Bovine Serum Albumin.

Reconstitution

and Storage:

Freeze-dried product should be stored refrigerated until opened. After opening, restore to suggested ml volume with distilled water. If it is not completely clear after standing for 1-2 hours at room temperature, centrifuge the product. It is stable for several weeks at 4°C as an undiluted liquid. Do not use for more than one day after dilution. For extended storage after reconstitution, we suggest aliquot to avoid repeated freezing and thawing; or the addition of an equal volume of glycerol to make a final glycerol concentration of 50%, followed by storage at -20°C. The concentration of protein and buffer salts will decrease to one-half of the original after the addition of glycerol.

Importance

Apo E contains 299 amino acid residues. It is a 34-37 kDa glycosylated protein (Rall et al., 1983).

Apo E is involved with triglyceride, phospholipid, cholesteryl ester, and cholesterol transport in and out of cells and is a ligand for LDL receptors. Apo E has also been implicated in immune and nerve degeneration. It has been found to suppress lymphocyte proliferation. Late-onset familial and sporadic Alzheimer disease patients have been found to have a higher occurrence of one of the three common Apo E isoforms, Apo E4. The Apo E4 isoform has been detected in senile plaques and neurofibrillary tangles of Alzheimer disease patients. Apo E4 is associated with rapid chylomicron-remnant clearance and increased total cholesterol levels.
