Anti-methylglyoxal antibody
(Anti MG monoclonal antibody, specific for argpyrimidine, clone #3C) |
|
| About methylglyoxal (MG) |
|
Methylglyoxal (MG), an endogenous metabolite
that increases in diabetes and is a common intermediate in the Maillard reaction (glycation), reacts with proteins and forms advanced glycation
end products (AGE). MG reacts with arginine residue in protein and forms numerous numbers of adducts, such as argpyrimidine.
This antibody is specific for argpyrimidine: N-(5-hydroxy-4,6-dimethylpyrimidine-2-yl)-L-ornithine.

Manufactured by NOF corporation, Japan. |

| Procedure |
| 1) |
Paraffin sections were deparaffinized and rehydrated. |
| 2) |
Sections were quenched for several minutes with 3% hydrogen peroxide,
rinsed in PBS, pretreated for 30 min with 3% nonimmune animal serum in PBS. |
| 3) |
Sections were incubated overnight at 4°C with a antibody at a
dilution of 1 µg/mL. |
| 4) |
Antibody binding was visualized by the avidin-biotin-immuno
peroxidase complex method using the Vectastain ABC kit (Vector, Burlingame, CA) according to the manufacturer's instructions. |
| 5) |
3,3-Diaminobenzidine tetrahydrochloride was used as the chromogen. |
| 6) |
Hematoxylin or Eosin was used as the counter stain. |
|
| Technical Note |
| 1) |
Sections from which the primary antibodies were omitted served as
negative reaction controls. |
| 2) |
For frozen materials, samples were fixed in 10% formalin,
immersed in 30% sucrose in PBS, embedded at OCT (Sakura, Tokyo, Japan), and stored at 80°C. |
| 3) |
For paraffin embedded materials, samples were fixed in 10% formalin,
dehydrated, embedded in paraffin, and stored at room temperature. |
| 4) |
Microwave treatment improves the target staining, whereas it
declines non-specific background. |
| 5) |
Protease K treatment declines the target staining. |

| Positive control |

Aortic wall in the renal tissue of diabetic nephropathy or
aortic wall of atherosclerosis. |
