Telomere length in PBMCs was measured using the methods described previously (Cawthon, 2009), with some modifications. We used 36B4 for reference as a single copy gene. The primer sequences (5′–3′) were: telomere forward: GGT TTT TGA GGG TGA GGG TGA GGG TGA GGG TGA GGG T; telomere reverse: TCC CGA CTA TCC CTA TCC CTA TCC CTA TCC CTA TCC CTA; 36B4 forward/reverse CAG CAA GTG GGA AGG TGT AAT CC; 36B4 forward/reverse CCC ATT CTA TCA TCA ACG GGT ACA A. The 36B4 reaction included 7.5 μL of SyBr Green PCR MasterMix (Promega, UK), 0.45 μL of primer forward, 0.75 μL of primer reverse and 3.3 μL of miliQ water. For telomere reaction: 7.5 μL of SyBr Green PCR MasterMix (Promega), 0.45 μL of primer forward, 0.45 μL of primer reverse and 3 μL of miliQ water.
The real-time polymerase chain reaction (PCR) was run with 7500 Fast Real Time PCR System (Promega, CA, USA) at 50°C for 2 minutes, then 40 cycles of 95°C for 2 minutes, 55°C for 15 seconds and 60°C for 1 minute.

The total RNA from each tissue, namely, the leaves, flowers, and roots, of three flowering tomato plants was extracted using TRIzol (Invitrogen) and purified using the RNA purification kit (Promega, Madison, WI USA). The concentration and purity of RNA were measured using Nanodrop (Thermo, Madison, WI, USA), and RNA integrity was detected by agarose gel electrophoresis. DNase was used to eliminate genomic DNA from the total RNA. Two micrograms of total RNA were used for cDNA synthesis using the GOSCRIPT Reverse transcriptional system (Promega). To determine the expression of lncRNA and transcripts of the coding gene, specific primers and SYBR Green PCR Master Mix (Promega) were used to perform qRT-PCR using Bio-Rad CFX manager 3.1 (Bio-Rad, Hercules, CA USA) [47 (link)]; actin was used as the standard.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
