- Figure 6 Binding of IgG and C3b with encapsulated strain of Bacillus anthracis incubated at different pH buffers ranging from 2.4 to 7.4, supplemented with 10% normal human serum or 50 mug/ml of purified human IgG. (A) Immunoblot assay for the detection of purified IgG binding on encapsulated strain of B. anthracis . IgG binding was observed at pH closer to the isoelectric point of poly-gamma-D-glutamate (pI 3.2). (B) Purified IgG was stable at different pH buffers as detected by immunoblot. (C) Immunoblot assay for the detection of human C3b binding on encapsulated strain of B. anthracis . C3b binding was also observed at pH closer to the isoelectric point of poly-gamma-D-glutamate. (D) Normal human serum (NHS) was incubated at different pH buffers and C3 was observed to be stable at low pH as analyzed by immunoblot.

- Figure 2 C3b deposition on encapsulated and non-encapsulated strains of Bacillus anthracis . (A) Flow cytometry histogram of C3b deposition on encapsulated and non-encapsulated B. anthracis strains incubated in 10% human serum. Gray and pink shading indicates non-encapsulated and encapsulated bacteria, respectively. Blue shading indicates bacteria incubated in phosphate-buffered saline (PBS) alone. (B) Mean fluorescence index (MFI) of serum concentration-dependent C3b deposition on encapsulated and non-encapsulated bacteria. Black and gray bars represent non-encapsulated and encapsulated strains, respectively. The scatter plots for the corresponding histograms are represented in Figure S3 . (C,D) Immunoblot assays to detect serum concentration-dependent C3b deposition on non-encapsulated (C) and encapsulated strains (D) ; 1% normal human serum was used as positive control. Each data point represents the mean of three independent experiments. Error bars represent standard error of the mean. Statistical significance is highlighted by the following denotations: ** for P -value < 0.01, and *** for P -value < 0.001.

- Figure 4 Contributory role of classical and alternative pathways in C3b deposition on Bacillus anthracis . Flow cytometry histogram for C3b deposition on non-encapsulated (A) and encapsulated (B) B. anthracis strains incubated in 10% human serum deficient in complement component C1q (C1q-), factor D (FD-), and C5 (C5-). Gray, red, and blue histogram shading represents C3b deposition in C1q-, C5-, and FD- deficient sera, respectively. (C) C3b binding represented as mean fluorescence index (MFI) observed with non-encapsulated (black bars) and encapsulated (gray bars) B. anthracis strains incubated in C1q and FD sera. Each bar represents the mean of three independent experiments. Error bars represent standard error of the mean. Statistical significance is highlighted by the following denotations: *** for P -value < 0.001.
