RDI Divison of researchd Industries Intl offers a wide line of antibodies. Since no one antibody works best for all applications (neutralization, blotting, histochemistry, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below.
note: we regret the producer has more than doubled their price on this product effective July 2001 so we now offer the 5ug size only

Anti-AGE Antibody Technical Information
Reaction of amino groups in protein with glucose leads to the formation of advanced glycation end products (AGE) through the early products such as Schiff base and Amadori rearrangement products.
Recent immunological studies using anti-AGE antibody (6D12) demonstrated the presence of AGE-modified proteins in several human tissues:
(I) human lens (non-diabetic and non-cataractous),
(ii) renal proximal tubules in patients with diabetic nephropathy and chronic renal failure,
(iii) diabetic retina,
(iv) peripheral nerves of diabetic neuropathy,
(v) atherosclerotic lesions of arterial walls,
(vi) b2-microglobulin forming anyloid fibrils in patients with hemodialysis-related amyloidosis,
(vii) senile plaques of patients with Alzheimer disease,
(viii) peritoneum of CAPD patients,
(ix) skin elastin in actinic elastosis, and
(x) ceroid/lipofusion 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 the antibody for histochemical identification and biochemical quantification of AGE-modified proteins. 6D12 does not recognize the early products, Schiff base and Amadori products. It, however, shows positive reaction to AGE-samples obtained either from proteins, lysine derivatives, or monoamino-carboxylic acids. This result indicates the immunospecificity of 6D12 to a common structure among AGE-structures. The epitope of 6D12 is an N3-carboxymethyllysine (CML)-protein adduct. This antibody also recognizes carboxyethyllysine. New antibodies, specific for advanced glycation end products (AGE products), will be added shortly.
[Package and properties]
Package: 5ug (0.25 mg/ml in PBS).
Clone Number: mouse monoclonal antibody 6D12.

The initial study (Horiuchi, et al., 1991) revealed that 6D12 does not recognize early products (Schiff base and Amadori products), but shows a positive reaction to AGE-samples obtained either from proteins, lysine derivatives or mono amino-carboxylic acids, indicating the immunospecificity to a common structure among AGE-structures. The subsequent study (Ikeda, et al., 1996) revealed the epitope of 6D12 is an N e-carboxymethyllysine (CML)-protein adduct.
