FIG. 4.
Immunophenotype of PBMCs that interact with SSLs. PBMCs were stained for various cell surface markers after incubation with 1.25 μM SSL7-FITC or SSL9-FITC for 60 min at 37°C. The results are representative of the results of five separate experiments. (a) SSLs with histidine tag. Ab, antibody. (b) Comparison of staining observed with SSL7-FITC with the histidine tag (SSL7H) (graphs on the right) and without the histidine tag (graphs on the left).
