The monoclonal antibody S9.6 binds DNA-RNA hybrids with high affinity, making it useful in research and diagnostic applications, such as in microarrays and in the detection of R-loops. A single-chain variable fragment (scFv) of S9.6 was produced, and its affinities for various synthetic nucleic acid hybrids were measured by surface plasmon resonance (SPR).(More)
Anthrax toxin protective antigen (PA) delivers its effector proteins into the host cell cytosol through formation of an oligomeric pore, which can assume heptameric or octameric states. By screening a highly directed library of PA mutants, we identified variants that complement each other to exclusively form octamers. These PA variants were individually(More)
Anthrax edema factor (EF) is a calmodulin-dependent adenylate cyclase that converts adenosine triphosphate (ATP) into 3'-5'-cyclic adenosine monophosphate (cAMP), contributing to the establishment of Bacillus anthracis infections and the resulting pathophysiology. We show that EF adenylate cyclase toxin activity is strongly mediated by the N-end rule, and(More)
Flagellar murine MAbs (53B and 29) to strain a-type 170018 (a0,a3,a4, 45 kDa) and a human a-type MAb were studied in ELISA, Immunoblot, colony blot, agglutination and motility assays to evaluate the degree of cross-reactivity within the dominant a0 epitope. No specific effect of possible subtypes (a1, a2, a3, a4) was observed. An association of(More)
The intestinal mucosa is a key anatomical site for HIV-1 replication and CD4+ T cell depletion. Accordingly, in vivo treatment with an antibody to the gut-homing integrin α4β7 was shown to reduce viral transmission, delay disease progression, and induce persistent virus control in macaques challenged with simian immunodeficiency virus (SIV). We show that(More)
The growth of preruminant calves and lambs fed on milk replacers containing vegetable proteins is generally inferior to that of preruminants given cows' milk. The inferior performance has variously been attributed to an amino acid imbalance, to heat damage in preparation, and to the presence of growth-retarding substances. Soybean products that have been(More)
A helical mycoplasma,Spiroplasma mirum strain SMCA, produced malignant transformation in mouse NIH 3T3 cells and monkey kidney CV-1 cells. The transformed cells exhibited morphological changes consistent with the transformed phenotype, grew in soft agar and produced tumors in athymic and BALB/c mice. Transmission electron microscopy revealed structures(More)
