Testing of TLR activity of rLsa21.
rLsa21 was screened for TLR2 activity on HEK293 cell lines transfected with TLR2 and NF-κB driven reporter plasmids by Luciferase assay (A) and induction of IL-8 (B) after stimulation with the protein and pretreatment with PK or blocking with TLR2 antibodies as described in material and methods. UI indicates uninduced or unstimulated cells, GST- indicates Glutathione S-transferase protein (2 μg/ml) PAM indicates PAM3CSK (20 ng/ml), PK is Proteinase K, PB is Polymixin B (10 μg/ml) and TLR is Toll like receptors.
