Similar to PCMS polyclonal CELspecific antibody PCES
Next, the monoclonal antibody specific for CML and both Group II and Group III were specific for other epitopes nonCML. Recent studies have indicated that methylglyoxal MG, which is generated intracellularly by glycolysis and polyol pathways, reacts with proteins to form MGderived AGE structures such as Ncarboxyethyllysine CEL, imidazolone and imidazolium salt crosslink like methylglyoxallysine dimmer MOLD. These results indicate that CMS10 would help detect CMLmodified proteins in vitro in more specific way. In the present study, we determined the possibility that antibody could recognize difference between CML and CEL.
These results suggest that AGEs accumulated in vivo serve as immunological epitopes for developing autoantibodies against AGEs, particularly against CML structure, which might be used as an indicator of diabetic nephropathy or chronic renal failure.

Our preliminary studies demonstrated that 6D12 and polyclonal antiCML antibody demonstrated CMLaccumulation in several pathological tissues such as kidneys of patients with diabetic nephropathy and atherosclerotic lesions of arterial walls. Traditional approaches for production of antiAGE antibodies use crosslinkers such as hydrochloride EDC to conjugate the AGE antigen to the carrier protein. It is likely therefore that these antibodies were able to recognize the difference in one methyl group between the two epitopes. Next, the monoclonal antibody specific for CML CMS10 was obtained by immunization of CMLKLH, followed by successive screening by CMLbovine serum albumin CMLBSApositive but CELBSAnegative criteria.

In sharp contrast, PCES showed high reactivity toward CELprotein, but not to CMLprotein. Next, the monoclonal antibody specific for CML and both Group II and Group III were specific for other epitopes nonCML. In the present study, Ncarboxymethyllysine CML, major antigenic AGE structure, was conjugated to human serum albumin HSA using various crosslinkers, including EDC, BS3 and glutaraldehyde, to compare their efficiency for the production of epitopespecific antibodies. 2G11 significantly recognized CMLmodified HSA and peptide, indicating that 2G11 is highly specific to CML, and can distinguish the difference of single methyl group between the two epitopes.
