Sybr green master mixes

Manufactured by Takara Bio
Sourced in China, Switzerland, Japan

SYBR Green master mixes are reagents used for quantitative real-time PCR (qPCR) experiments. They contain SYBR Green I, a fluorescent dye that binds to double-stranded DNA and emits a signal proportional to the amount of DNA present. These master mixes provide all the necessary components, including DNA polymerase, nucleotides, and buffer, for efficient and accurate qPCR analysis.

The total RNA was extracted from the liver tissue using Trizol Reagent (Invitrogen, Carlsbad, CA, USA), and cDNA was synthesized from RNA (1 μg) using the reverse transcription reagent kit (TaKaRa, Dalian, China). Real-time PCR was performed with SYBR Green master mixes (TaKaRa, Dalian, China) using a CFX96 Real-Time PCR system (Bio-Rad, Hercules, CA, USA) with the thermal cycle conditions: 1 cycle at 95 °C for 30 s; 40 cycles at 95 °C for 5 s and at 61 °C for 35 s. The primer sequences are listed in Table 2, and the mRNA expressions of the target genes were normalized to that of β-actin and calculated using the 2−△△CT method.

Brain tissues of the same region (2.0–4.0mm posterior to the frontal pole) were obtained with coronal cut and were divided into ipsilateral and contralateral hemispheres. Total RNA of ipsilateral and contralateral hemispheres was isolated by using Trizol (Takara), and 1 μg of total RNA was reverse-transcribed to cDNA using PrimeScriptTM RT Master Mix Kit (Takara). RT-qPCR was performed with Roche LightCycler480 System (Roche, Basel, Switzerland) by using SYBR Green master mixes (Takara). Quantification was performed by the delta cycle time method, with mouse β-actin used for normalization. The mouse-specific primers (Sangon Biotech, Shanghai, China) are listed in Table 2.

Total RNA extraction was conducted using TRIzol (Invitrogen, Carlsbad, CA, USA) based on manufacturers' specifications. Using the M-MLV RT kit (Promega, Madison, WI, USA), 2 μg RNA was reverse-transcribed into cDNA. The PCR reaction using resultant cDNA was conducted using the following primers: Ku70: 5′-GTGGTCACACACGAGCTTATT-3′ (sense) and 5′-CAAATGTCTGATGTTGGTGAACC-3′ (antisense) and β-actin: 5′-TGGATCAGCAAGCAGGAGTA-3′ (sense) and 5′-TCGGCCACATTGTGAACTTT-3′ (antisense). The thermal cycle for PCR was set as follows: 95°C for 2 min, 30 cycles of 94°C for 30 s, 56°C for 45 s, and 72°C for 45 s, with a final extension at 72°C for 7 min on a Lightcycler 480 system (Applied Biosystems, Foster City, CA, USA) using the SYBR Green Master Mixes (Takara, Japan). The Ku70 expression level was normalized to β-actin followed by the quantification through the 2−ΔΔCt method [15 (link)].

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.
