(Catalog #MOG-020 for 20 microgram vial)
(Anti 8-OHdG monoclonal antibody, clone N45.1)
What is 8-OHdG?
Reactive oxygen species (ROS) and oxidative stress may be crucial for
development
of various diseases such as diabetes, cancer, and may play
an important role in the
aging process. 8-hydroxy-2'-deoxyguanosine
(8-OHdG) is a product of oxidatively
damaged DNA formed by hydroxy
radical, singlet oxygen and direct photodynamic
action. 8-OHdG can
be detected in tissue, serum, urine and other biomaterials.
Anti 8-OHdG
monoclonal antibody (clone N45.1) is highly specific for 8-OHdG,
and
is suitable for immunohistochemistry.

Epidermis from hairless mouse by chronic UVB irradiation
after 4 weeks
of treatment stained with N45.1.

IMMUNOHISTOCHEMISTRY
This is an application example for anti 8-OHdG monoclonal antibody (clone N45.1). Experimental conditions should be determined individually by each user.
1) Fixation:
Fix the fresh tissues with Bouin’s Solution (Saturated Picric Acid: Formaldehyde: Acetic Acid : H2O = 15:5:1:10) overnight.
Please note that use of specimens fixed in the same conditions are recommended for quantitative analyses.
2) Deparaffinization (In case of paraffin embedded specimens):
Deparaffin with xylene and ethanol.
3) Antigen Retrieval (In case of fixation with formaldehyde):
Microwave method or Autoclave method is recommended.
4) 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).
