Anti Pyrraline Monoclonal Antibody


Reaction of protein amino groups with glucose leads, through the early products such as a Schiff base and Amadori rearrangement products, to the formation of advanced glycation end products (AGE). Recent immunological studies using anti-AGE antibody (6D12) demonstrated the presence of AGE-modified proteins in several human tissues: (1) human lens (nondiabetic and noncataractous), (2) renal proximal tubules in patients with diabetic nephropathy and chronic renal failure, (3) diabetic retina, (4) peripheral nerves of diabetic neuropathy, (5) atherosclerotic lesions of arterial walls, (6)β2-microglobulin forming amyloid fibrils in patients with hemodialysis-related amyloidosis, (7) senile plaques of patients with Alzheimer’s disease, (8) the peritoneum of CAPD patients, (9) skin elastin in actinic elastosis, and (10) ceriod/lipofuscin deposits. These results suggest a potential role of AGE-modification in normal aging as well as age-enhanced disease processes. This antibody named as 6D12 has been used to demonstrate AGE-modified proteins in these human tissues, indicating potential usefulness of this antibody for histochemical identification and biochemical quantification of AGE-modified proteins.

Pyrraline is one of the major Maillard compounds resulting from the reaction of glucose and amino coumpounds at slightly acidic pH. Using anti-pyrraline antibody, pyrraline was detected in sclerosed glomeruli from diabetic and normal old kidneys as well as in renal arteries with arteriosclerosis. Furthermore, it was detected in neurofibrillary tangles and senile plaques in brain tissue from patients with Alzheimer’s disease.

Package Size 20µg (80µL/vial)
Mouse monoclonal antibody 0.25 mg/mL
Block Ace as a stabilizer, containing 0.1% Proclin as a bacteriostat
Storage Store below -20°C
Once thawed, store at 4°C. Repeated freeze-thaw cycles should be avoided.
Clone No. H12
Subclass IgG1
Purification method The splenic lymphocytes from BALB/c mouse, immunized with pyrraline-HSA were fused to myeloma P3U1 cells. The cell line (H12) with positive reaction was grown in ascitic fluid of BALB/c mouse, from which the antibody was purified by Protein G affinity chromatography.
Working dilution for immunohistochemistry: about 2µg/mL; for ELISA: 0.1-0.5µg/mL
