Figure S1. TLR4, CD14, MD-2, and MyD88 mRNA expression in mpkCCD_cl4 cells. (A) mpkCCD_cl4 cells formed confluent cell layers and also formed domes (asterisks). Bar, 50 μm. (B) RT-PCR identification of amplified products for TLR4 (311 bp), CD14 (703 bp), MD-2 (316 bp), and MyD88 (660 bp) mRNAs. + represents reverse-transcribed RNA; − represents non–reverse-transcribed RNA.
