What is 4-HNE?
Reactive oxygen species (ROS) are involved in lipid peroxidation inside the living bodies, and membrane lipids are one of the major targets of ROS. During the peroxidation process, a variery of aldehydes are formed. 4-hydroxy-2-nonenal (4-HNE) is an alpha, beta unsaturated aldehyde that can be formed by peroxidation of omega-6 unsaturated fatty acids such as linoleic acid and arachidonic acid. Especially, 4-HNE formed inside living body is reported to originate from phospholipid-bound arachidonic acid. 4-HNE may be one of the most reliable biomarker of lipid peroxidation.

IMMUNOHISTOCHEMISTRY

This is an application example for anti 4-hydroxy-2-nonenal (4-HNE) monoclonal antibody, clone HNE-J2. (Catalog #MHN-020P/ and MHN-100P).

      
1) Fixation:

Fixation using Bouin's solution is recommended.
In this case, antigen retrieval process is not required.

2) Avidin Biotin Complex (ABC) Method:

a)
Apply normal rabbit serum (Diluted to 1:75) (DAKO corporation, Kyoto, Japan) to the specimens for the inhibition of non-specific binding of secondary antibody.
b)
Apply N45.1 (1-10microgram/ml) to the specimens, incubate overnight at 4 degree C.
c)
Apply biotin-labeled rabbit anti-mouse IgG serum
(Dako; Diluted to 1:300) for 40min at room temperature.
d)
Apply avidin-biotin-alkaline phosphatase complex (Vector Lab., Burlingame, CA; Diluted to 1:100) for 40min at room temperature.
e)
Staining. Use a kit of black substrate for alkaline phosphatase (Vector).

 

2)  Antigen Retrieval (In case of fixation with formaldehyde): 

Microwave method or Autoclave method is recommended.
