  • $832.00


Host Species: Goat
Concentration: 1 mg/ml (OD 1.35 / 280 nm)
Antigen: 4 HNE-KLH
Purification: Affinity purified
Buffer: 75 mM Sodium Phosphate, 75 mM NaCl, 0.5 mM EDTA, 0.02% NaN3, pH 7.2
Specificity

Specifically binds to 4-HNE-modified proteins. Molar F/P ratio is 4.7. The investigator should determine working dilutions.

Use:

The antibody can be used for detection of of 4-HNE modification in plasma, lipoproteins, and other proteins, 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: 5 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

Modifications on lysine residues, with formation of carboxylmethyl-lysine (CML), malondialdehyde (MDA) and hexitol-lysine are advanced glycation end-products (AGE), and the coupling with reactive aldehyde compounds, such as 4-hydroxynonenal (4-HNE) may appear from lipid oxidation (Guichardant et al., 1998). These modifications feature the oxidative byproducts which react with NH2 groups and form Schiff-base adducts (Mark et al., 1996). LDL treated with HNE or oxidatively modified by Cu++ or by cultured endothelial cells give rise to Michael addition-type HNE adducts that are recognized by HNE-specific antibodies.
