click-chemistry mediated activity-based probe, N-but-3-ynyl-2-chloroacetamidine, is shown to label myc-tagged DDAH-1 expressed in HEK 293T cells, but not an inactive mutant or inhibited enzyme. A two-color Western blotting technique is used to determine the in vivo IC(50) value for a reversible inhibitor of DDAH-1, N(5)-(1-iminopropyl)-l-ornithine, indicating this compound's bioavailability and its competition
