TLR4 Staining Analysis

TUMOR
Slides from the formalin-fixed paraffin-embedded tumor blocks were stained with hematoxylin-eosin and with antibodies to TLR4 (MAB14783; R&D Systems) and analyzed by Mosaic Laboratories. A pathologist confirmed tumor presence using hematoxylin-eosin, and immunohistochemical findings were scored on a positivity scale of 0 (absent) to 3+ (strong). Banked tumor formalin-fixed paraffin-embedded blocks from previous institutional review board–approved protocols were also stained.
