IL-1b and IL-18 first exist in Pro- form and then be cleaved to become a mature form. I tried to find antibodies that can measure the cleaved forms of IL-1b and IL-18, but not success.
IL-1b: there are many antibodies can measure pro form, but not sure if the clone 166931 from R&D can measure the cleaved form of IL-1b.
IL-18: basically I can not find any antibody.
Is any one can help me out? Thanks in advance
