Figure 1From: Clinical evaluation of a matrix metalloproteinase-12 cleaved fragment of titin as a cardiovascular serological biomarkerSpecificity of the antibody to the selection peptide vs. non-reactivity to the elongated peptide. (A) The signal was assessed as the optical density at 450 nm, subtracting the background at 650 nm, as a function of peptide concentration. LLD was found to be 5.43. Point zero represents increased signal inhibition and therefore elevated levels of the epitope in serum.Back to article page
