Figure 1From: Influence of cytokine inhibitors on concentration and activity of MMP-1 and MMP-3 in disc herniationDifferent forms of matrix metalloproteinase enzymes and their usual nomenclature. Immunocapture activity assays (used in the present study) detect both total matrix metalloproteinase (MMP) activity and active MMP, while the standard ELISA method detects total MMP (inactive, active and inactivated forms). TIMP, tissue inhibitor of matrix metalloproteinase.Back to article page
