[H10] HRP-conjugated Goat Anti-Human Apolipoprotein E
50H-G1aHost Species: | Goat |
Concentration: | 1 mg/ml (OD 1.35 / 280 nm) |
Antigen: | Human Apolipoprotein E |
Purification: | Affinity purified |
Buffer: | 50 mM PBS, 0.1 M NaCl, and 0.01% Thiomersal, pH 7.4. |
Specificity | Specifically binds to human apo E. Dilution for immunoblot and ELISA range: 1,000 to 8,000. |
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.
