The expression of CB1 and CB2 mRNA in EL-4, LSA, and P815 tumor cells.
The expression of CB1 and CB2 mRNA was determined by RT-PCR analysis. Total RNA was isolated from EL-4, LSA, and P815 tumor cells. mRNA was reverse transcribed and amplified by PCR with primers specific for CB1 and CB2. A photograph of ethidium bromide–stained amplicons is depicted.
