Vic labeled actb probe

RNA was purified using the GenElute Mammalian Total RNA Miniprep Kit (Sigma-Aldrich) and cDNA generated using the High Capacity cDNA Reverse Transcription Kit (Applied Biosystems). Quantitative PCR (qPCR) was then performed using the manufacturer’s protocol for the PCR Master Mix (Applied Biosystems). Transcript abundance was measured using a JMJD5-specific FAM-labeled TaqMan probe (Hs00227070_m1) and an internal loading control (VIC-labeled ACTB probe; 4326315E) (Thermo Fisher Scientific). qPCR was performed on a QuantStudio 5 Real-time PCR System (Thermo Fisher Scientific), and the comparative 2^–ΔΔCt method was used to quantify transcript abundance.

Total RNAs were isolated from brain regions and peripheral tissues using the TRIzol Reagent. Single strand cDNAs were synthesized using qScript XLT cDNA SuperMix (Quantabio, Beverly, MA, USA, #95161-500). Rodent isoform CB1A [3 (link)] and CB2A [4 (link)] FAM-labeled probes and endogenous control VIC-labeled Actb probe (Thermo Fisher Scientific Inc., Waltham, MA, USA, #4352341E) were used for TaqMan RT-qPCR. To validate hepatocyte CB1R detection, TaqMan PreAmp Master Mix Kit (Thermo Fisher Scientific Inc., Waltham, MA, USA, #4391128) or PerfeCTa PreAmp SuperMix (Quantabio, Beverly, MA, USA, #95146-005) was used for cDNA preamplification using 80 nM of forward and reverse primer sets [48 (link)]. cDNAs were pre-amplified using the program: 95 °C hold for 10 min and then 10 cycles of denaturation at 90 °C for 15 s and annealing and extension at 60 °C for 4 min. Duplex PCR assays containing both the target and endogenous control TaqMan probes were carried out with Advanced TaqMan Fast PCR Master Mix (Thermo Fisher Scientific Inc., Waltham, MA, USA, #4444556) or PerfeCTa Multiplex qPCR ToughMix (Quantabio, Beverly, MA, USA, #95147-250) in StepOnePlus instrument using a default thermo-cycling program. The relative fold change is calculated using the formula: 2^{(−△△Ct)} [48 (link)].
