Total RNA was extracted from the transfected cells 72 hours post-transfection using the NucleoSpin® RNA Plus (Clontech, cat# 740984.250), and 250 ng of purified RNA was used for cDNA synthesis using High-Capacity RNA-cDNA kit (ThermoFisher, cat# 4387406). cDNA was diluted 1:20 and 3 ul of cDNA was used for quantitative PCR (qPCR). qPCR reaction samples were prepared using cDNA, SYBR (ThermoFisher, cat# 4385612), and primers detecting each target transcript. Primer sequences are listed in Supplementary Table 2. qPCR was performed using Roche LightCycler480 with the following cycling protocols (Supplementary Table 2). When Ct values are over 35, we considered them as 35, because Ct values fluctuate for very low expressed transcripts. Samples that were transfected with LbCpf1 crRNA backbone plasmid, BPK3082 were used as negative controls, and the levels of fold activation over negative controls were normalized to the expression of HPRT1.

For gene expression assays, total RNA was isolated from cells using NucleoSpin RNA Plus (Clontech). cDNA was obtained using a high-capacity RNA to-cDNA kit (Applied Biosystems). 500 nanograms of template total RNA and random hexamers were used for each reaction. Real-time PCR amplification was performed using fast SYBR Green Master Mix (Life Technologies) and specific PCR primers in a Lightcycler 480 instrument (Roche). Oligonucleotides used are provided in Table S1. Relative quantification of each target, normalized to an endogenous control (GAPDH or HPRT1), was performed using the comparative Ct method (Applied Biosystems). Error bars indicate SD of three technical replicates and represent at least two independent biological experiments. Statistical analyses were performed by Student’s t test. In heatmaps, log2 qRT-PCR expression values were averaged across biological replicates in each condition and scaled for each gene.

Total RNA was isolated from cells using NucleoSpin RNA Plus (Clontech). For Figure 2H, RNA libraries were prepared from 500 ng of total RNA treated with Ribogold zero to remove rRNA using TruSeq Stranded Total RNA Library Prep Gold kit (Illumina, 20,020,599) and TruSeq RNA Single Indexes. The RNA libraries were sequenced with PE 32 cycles on an Illumina Nextseq500 system. For Figure 3G, RNA samples were sent to Novogene Corporation for mRNA sequencing. RNA libraries were sequenced with PE150 cycles on an Illumina NovaSeq 6000 system. Reads were aligned to hg19 using STAR.59 (link) Mapped reads were filtered to exclude PCR duplicates and reads mapping to known rRNA coordinates, obtained from the rmsk table in the UCSC database (http://genome.ucsc.edu). Gene expression was calculated using featureCounts.60 (link) Only primary alignments with mapping quality of 10 or more were counted. Counts were then normalized to one million reads.

Total RNA isolation was performed using NucleoSpin RNA Plus (Takara Bio), after which RNA concentrations were measured using a NanoDrop (Thermo Fisher Scientific, Waltham, MA, USA). A total of 500 ng of RNA was used for reverse transcription with the PrimeScript RT reagent kit (Takara Bio). cDNA templates were subjected to qPCR analysis using the TaqMan Gene Expression Assay Mastermix and TaqMan probes (Thermo Fisher Scientific) with a StepOnePlus Real-Time PCR System (Thermo Fisher Scientific). The probe list for the TaqMan gene expression assays is shown in Supplementary Table 5. Each amplification reaction was performed in triplicate, and the average of three threshold cycles was used to calculate the relative amount of transcript in the sample (StepOne Software; Thermo Fisher Scientific). mRNA was quantified and expressed in arbitrary units as the ratio of the sample quantity to the calibrator or the mean values of control samples. All values were normalized to an endogenous control, the human β-actin gene.

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.
