Flow Cytometry: Human TLR9 Stable Cell Line [NBP2-26272] - analysis of TLR9 expression in the TLR9 stable cell line. Intracellular expression of TLR9 in the TLR9 stable cell line was analyzed by flow cytometry using a PE-conjugated TLR9 antibody and compared with the Vector control stable cell line. Intracellular TLR Staining Flow Kit was used for this test.
