Formalin-fixed and paraffin-embedded human lung carcinoma labeled with Anti-IDO Polyclonal Antibody, Unconjugated(bs-15493R) 1:200, overnight at 4°C, The secondary antibody was Goat Anti-Rabbit IgG, FITC conjugated(bs-0295G-FITC)used at 1:200 dilution for 40 minutes at 37°C.


Mouse spleen cells(black) were fixed with 4% PFA for 10min at room temperature,permeabilized with PBST for 20 min at room temperature, and incubated in 5% BSA blocking buffer for 30 min at room temperature. Cells were then stained with IDO Polyclonal Antibody(bs-15493R)at 1:50 dilution in blocking buffer and incubated for 30 min at room temperature, washed twice with 2%BSA in PBS. Acquisitions of 20,000 events were performed. Cells stained with primary antibody (green), and isotype control (orange).


Mouse spleen cells were fixed with 4% PFA for 10min at room temperature,permeabilized with 0.1%PBST for 20 min at room temperature, and incubated in 5% BSA blocking buffer for 30 min at room temperature. Cells were then stained with IDO Polyclonal Antibody(bs-15493R)at 1:100 dilution in blocking buffer and incubated for 30 min at room temperature, washed twice with 2%BSA in PBS, followed by secondary antibody incubation for 40 min at room temperature. Acquisitions of 20,000 events were performed. Cells stained with primary antibody (green), and isotype control (orange).


HUVEC cell; 4% Paraformaldehyde-fixed; Triton X-100 at room temperature for 20 min; Blocking buffer (normal goat serum, C-0005) at 37°C for 20 min; Antibody incubation with (IDO) polyclonal Antibody, Unconjugated (bs-15493R) 1:100, 90 minutes at 37°C; followed by a conjugated Goat Anti-Rabbit IgG antibody at 37°C for 90 minutes, DAPI (blue, C02-04002) was used to stain the cell nuclei.
