ANXA5 and infection: Technetium-99m (99mTc) has been used to detect infection by labeling it to annexin V, which binds to apoptotic cells (by Tang et al. [76]); ciprofloxacin, which targets living bacteria by binding to DNA gyrase (by Sarda et al. [74]); and ubiquicidin (UBI) 29-41, an antimicrobial peptide that binds to bacterial cell membranes (by Sarda-Mantel et al. [75]).
