Fig. 1From: Highly sensitive therapeutic drug monitoring of infliximab in serum by targeted mass spectrometry in comparison to ELISA dataSchematic structure of infliximab and its amino acid sequence depicting Fab heavy and light chains. Blue regions represent conserved peptide sequence, red shows unique amino acid sequences and green the hypervariable regions and interaction points with TNFa. The Peptide sequences selected for quantification are marked with bold and underlinedBack to article page
