Rna reverse transcriptase kit

Manufactured by Takara Bio
Sourced in Japan

The RNA reverse transcriptase kit is a laboratory tool used to convert RNA molecules into complementary DNA (cDNA) strands. This process, known as reverse transcription, is a fundamental step in various molecular biology techniques, such as gene expression analysis and cDNA library construction.

HCT-8R cells were treated with IGF-1, AKT inhibitor and 3-MA. Total RNA was extracted using the RNeasy kit (Qiagen GmbH, Hilden, Germany) and transcribed into cDNA with an RNA Reverse Transcriptase kit (Takara Bio, Inc., Otsu, Japan). qPCR was performed with a SYBR®Green PCR assay (Takara Bio, Inc.) according to the manufacturer's protocol (95°C for 1 min, and 40 cycles of 95°C for 5 sec and 60°C for 35 sec, followed by a final standard dissociation protocol), using the primers listed in Table I. Expression of GAPDH served as an internal control. The results were analyzed using the comparative Cq method (2-ΔΔCq) (15 (link)).

RNA Extraction and RT-qPCR Quantification

Check if the same lab product or an alternative is used in the 5 most similar protocols
For RT-PCR analysis, total RNA was isolated with a Total RNA Kit II (OMEGA, BioTek, D6934-01) in RNase-free conditions from cells lysed in RNA lysis buffer and then reverse transcribed into cDNA with RNA reverse transcriptase kit (TaKaRa, RR037A) according to the manufacturer’s protocol. RT-PCR was then performed with a TB Green PCR kit (TaKaRa, RR820A) using the ABI QuantStudio™ 7 Flex Real-Time PCR System (Applied Biosystems) to determine the expression levels of the genes of interest. The mouse organ tissues were homogenized to detect the virus gene copy number by qPCR (TaqMan™ Universal Master Mix II with UNG, 4440044, Applied Biosystems). All primers were synthesized by the Beijing Genomics Institute (Shenzhen, China). The primer sequences are listed in Supplementary Table 1.

The total RNA from abdominal aortic tissue were extracted by Trizol (Life Technologiese Invitrogen, Shanghai, China). A total 1 μg of RNA was used to synthesize cDNA and served as a template for amplification of UCP-2 by RNA reverse transcriptase Kit (Takara, Dalian, China). The forward primer of UCP-2 was 5’-AACAGTCCCAGACAGCCTACA-3’ and the reverse primer was 5’-CCTTCTTTCACTCCCATTTCC-3’ (767bp). The amplification was performed by Quantitative Real-time PCR by a SYBR green premix according to the manufacturer’s guide (SYBR Real-Time PCR Kit, Takara, Dalian, China). Mouse 18S ribosomal RNA were used as endogenous controls. Relative expressions of target genes were standardized to GAPDH, evaluated by the 2-ΔΔCT method and given as a ratio to control the experiments.

Total RNA was extracted from the TECs using a Total RNA Kit II (Omega Bio-tek, USA) according to the manufacturer’s instructions. Complementary DNA (cDNA) was synthesized from 1 μg of total RNA using an RNA reverse transcriptase kit (TaKaRa, Japan). Real-time quantitative PCR was performed using an ABI PRISM 7000 sequence detection system (Applied Biosystems), and a TaKaRa SYBR Premix Ex Taq II Kit was used for amplification according to the manufacturer’s instructions. The cDNA input was standardized, and 40 cycles of PCR were performed.

The concentration and quality of RNA were determined using an ultraspectrophotometer (model: NANODROP 2000, Thermo Fisher Scientific, USA). The RNA reverse transcriptase kit (Takara; 37°C for 60 min, 85°C for 5 min) was used. The following program was then applied according to the instructions of the expansion kit (Takara, China): 10 s at 95°C, 5 s at 95°C, 20 s at 60°C, 60 s at 95°C, 30 s at 55°C, 30 s at 95°C for 40 cycles. The 2 -ΔΔCT method was used to determine mRNA levels. The primer sequences of IL-6, IL-1β, and MCP-1 are shown in table 1.

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.
