TNF receptor messenger RNA expression by MMB3.19 cells.

Messenger RNA (mRNA) was isolated from MMB3.19 (lanes 5-7) and WEHI164 (lanes 2-4) cells and reverse transcribed to produce complimentary DNA (cDNA). Primers for GADPH (lanes 2 and 5) and TNF receptors type I (lanes 3 and 6) and type II (lanes 4 and 7) were used for PCR, and the products were resolved on an agarose gel.
