Figure Legend Snippet: A Relative fluorescence unit (RFU) of F598 mAb binding with the library of 32 PNAG pentasaccharides. The glycans are grouped according to the number of NHAc units in the molecule. Each PNAG sequence is printed five times on the glycan microarray. The error bars represent the standard deviations of five individual spots. Data are presented as mean values ± standard deviation. F598 generally prefers highly acetylated PNAG sequences. Both the location and the number of NHAc units are important determinants of F598 binding. B Quantification of the preference of F598 for acetylation at each site of the PNAG pentasaccharide. The mean values are calculated from the values of the binding intensities of all 32 PNAG sequences to F598. Each PNAG sequence is printed five times on the glycan microarray. Data are presented as mean values ± standard deviation. Source data are provided as a file.
Techniques Used: Fluorescence, Binding Assay, Sequencing, Glycoproteomics, Microarray, Standard Deviation
Figure Legend Snippet: A IgG antibody titers to the immunizing PNAG oligosaccharide in rabbit ( n = 2 per group) sera on day 35 after prime vaccination. B IgG antibody titers in pooled rabbit sera from mQβ-conjugate or 5GlcNH 2 –TT conjugate immunized animals ( n = 2 per group) as well as titer of natural human IgG in pooled human serum against native PNAG polysaccharide purified from Acinetobacter baumannii . The numbers above symbols are the average titer numbers. Titers and 95% confidence intervals (CI) were determined by linear regression using log 10 values of the average of replicate serum dilutions to determine the X intercept and 95% CI when Y = 0.5 (OD 405 nm of ELISA plate reading). C Stacked bar graphs depicting the IgG signals at the serum dilution of 1:50,000 for each rabbit ( n = 2) immunized with mQβ–PNAG0, mQβ–PNAG10, and mQβ–PNAG26 as well as pre-immune sera, respectively, on the array. The complete microarray results are provided in the file; D Normalized binding of the comprehensive library of PNAG pentasaccharides by IgG antibodies from post-immune sera of rabbits immunized with mQβ–PNAG0, mQβ–PNAG10, and mQβ–PNAG26, respectively, as well as pre-immune sera. PNAG sequences are grouped together according to the total number of acetamides in the molecules. The color scale bar is shown on the right with 100% indicating the strongest binding to a PNAG component and 0% indicating the weakest binder. For each antigen, the two rows represent sera from two rabbits per group immunized with the specific construct. Source data are provided as a file.
