[B15] Biotinylated Goat Anti-4 HNE (4 Hydroxynonenal)HNE40B-G1a
|Concentration:||1 mg/ml (OD 1.35 / 280 nm)|
|Buffer:||75 mM Sodium Phosphate, 75 mM NaCl, 0.5 mM EDTA, 0.02% NaN3, pH 7.2|
Specifically binds to 4-HNE modified proteins. Dilution for immunoblot and ELISA range: 1,000 to 8,000. (A slight amount of precipitation may have occurred during storage due to the natural properties of these antibodies; please centrifuge before 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:||10 mg / ml Bovine Serum Albumin.|
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.

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.
