  • RelevanceN epsilon carboxymethyl lysine (CML or Carboxymethyl Lysine) is formed by the non enzymatic Schiff base reaction of glucose with proteins, followed by an Amadori rearrangement and oxidation that leaves only a carboxymethyl group attached to the lysine. The levels of CML adducts accumulate over time and have been used as an indicator of both serum glucose levels and oxidative protein damage. Elevated serum CML modified proteins have been associated with diabetes and may contribute to diabetic retinopathy, nephropathy and angiopathy.
  • Alternative names
    • CML antibody
    • N Epsilon (Carboxymethyl) Lysine antibody

  • ab27684 staining Carboxymethyl Lysine in Mouse lung tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was fixed with paraformaldehyde, permeabilized with 0.5% Triton X-100 and blocked with 5% serum for 1 hour at 25°C. Samples were incubated with primary antibody (1/1000) for 12 hours at 4°C. A biotin-conjugated anti-rabbit IgG polyclonal (1/500) was used as the secondary antibody.

Thanks for your call earlier this week and for your patience. I have looked through some literature, and I think the best positive control for these markers that we will have are the human squamous cell carcinoma slides ab5107-
