Quantitation of TLR4 Internalization in Response to LPS in Thioglycollate Elicited Peritoneal mouse Macrophages by Flow Cytometry.

Internalization of cell surface Toll Like Receptor 4 (TLR4) is a convenient read-out to measure LPS dependent activation of the TRIF adaptor pathway. We here provide a protocol to quantify the LPS dependent internalization of TLR4 using thioglycollate-elicited peritoneal macrophages by flow cytometry.
