- Product Info
-
Immunogen: 8-hydroxy-guanosine-BSA and – casein conjugates
Sub class: IgG2A Host: Mouse Clonality: Monoclonal Purity: Total IgG fraction. Protein G purified. Format: Liquid Quantity: 25 µg Storage: Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube. Tested applications: ELISA (ELISA), Immunoaffinity chromatography (IAP), Immunohistochemistry on frozen tissue and paraffin-embedded (IHC-Fr-P) Recommended dilution: The optimal working dilution should be determined by the investigator - Reactivity

- Background
-
Background: Oxidative derivate of guanosine is called 8-Hydroxyguanosine (8OHdG) and is used as a popular biomarker of oxidative stress.

Immunostaining using anti-hydroxyguanosine monoclonal antibody
Tissue Preparation
Anti-hydroxy guanosine antibody monoclonal antibody reacts on both 50 µm frozen tissue sections and paraffin-embedded sections. Tissue should be dissected fresh and fixed in periodate-lysineparaformaldehyde (PLP) at 4°C
overnight.
PLP
Heat 1 L dest. water to 60°C. Add 60 g paraformaldehyde. Add 33 g dibasic NaPO4. Cool to room termperature in a cold water bath. Add 9 g monobasic NaPO4
.
Add 6.45 g Na-m-periodate.
Add 41.1 g lysine (HCl salt).
Filter and dilute to 3 L with dest. water. Adjust pH to 7.6 with 1.0 N NaOH
approx. (20-30 ml).
Tissue prepared for frozen sectioning must be cryoprotected in a 20% glycerol-2% DMSO solution in phosphate buffer for 24-48 hours. Tissue will sink to the bottom of container when fully penetrated. This will eliminate freezing artifact from cutting.Glycerol-DMSO (for 3 L)
2.4 L 0.1 M phosphate buffer
600 ml glycerol
60 ml DMSO0.1 M Phosphate Buffer, pH 7.4 (for 1 L)
1 L dest. water
11 g dibasic NaPO4
3 g monobasic NaPO4
After frozen sectioning, tissue should be stored in phosphate buffer with 0.08% sodium azide.Staining Sections By DAB Procedure
Paraffin-embedded sections must be deparaffinized by sequential immersion in the following for 3 minutes each: xylene (twice), absolute ethanol (twice). Agitate gently in each solution. Proceed with the following procedure:
1. Pretreat sections with a methanolperoxide solution to eliminate endogenous peroxidases.Methanol-Peroxide
100 ml absolute methanol
1 ml 33% H2O2
Incubate sections in methanolperoxide
solution for 30 minutes, room temperature.
2. Wash sections 3 times for 10 minutes each in 0.1 M phosphate buffered saline (PBS)
PBS, pH 7.4 (for 1 L)
1 L dest. water
11 g dibasic NaPO4
3 g monobasic NaPO4
8.5 g NaCl
3. Incubate sections for 1 hour in 10% normal goat serum in PBS.
4. Incubate sections in the primary antibody for 18-24 hours at room temperature. Depending on the nature
of the sample, a shorter incubation time may be used. - Reviews:
