- Western blot was performed using Anti-Complement C3b Monoclonal Antibody (755) (Product # MA1-40155) and a 187 kDa band corresponding to Complement C3 was observed in HepG2 in comparison to HEK-293 which is reported to be negative. A band around 70 kDa was also observed in Hep G2 treated with LPS and PTI which can be the processed form of complement C3. Whole cell extracts (30 µg lysate) of Hep G2 (Lane 1), Hep G2 treated with LPS (10 ng/mL for 18 hr) followed by protein transport inhibitor (1X for 4 hr) (Lane 2) and HEK-293 (Lane 3) were electrophoresed using NuPAGE™ 4-12% Bis-Tris Protein Gel (Product # NP0322BOX). Resolved proteins were then transferred onto a Nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with the primary antibody (1:50 dilution) and detected by chemiluminescence with Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:4000 dilution) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using SuperSignal™ West Dura Extended Duration Substrate (Product # 34076).

- Figure 7 Interaction between complement system and peptidorhamnomannans (PRMs) of Sporothrix species. (A) Sporothrix yeasts were opsonized with C3b and labeled with mouse anti-C3b mAb and mouse TRITC-IgG (Ab). PRMs (50 ug/ml in 50 mM carbonate buffer, pH 9.6) were coated on 96-well plate: their (B, C) C3 activation capacities were determined using GVB+ or GVB- (with EGTA) media using whole/complement factor-depleted human sera. (D ) Interaction with CD11b was determined by sequential addition of CD11b, mouse anti-CD11b mAb, peroxidase-conjugated mouse IgG, and chromogenic substrate for peroxidase (tetramethyl benzidine); colors developed were optically read at 450 nm. For each condition, two independent experiments, in triplicate, were performed. Statistical analysis was performed by ANOVA with Tukey's multiple comparison posttest (****p < 0.0001).
