5 protocols using wonder rt cdna synthesis kit

1

Macrophage Polarization Profiling by RT-qPCR

Check if the same lab product or an alternative is used in the 5 most similar protocols
Macrophage polarization and anti-inflammatory activity was evaluated by Real-Time Quantitative PCR (RT-qPCR) according to the manufacturer’s protocols. For RT-qPCR, total RNA was extracted from cells through TriFast (EuroClone, Milan, Italy), and cDNA was synthesized using Wonder RT cDNA synthesis Kit (EuroClone). Then, gene expressions of TNF-α, IL-1β, CCL18, CD206, IL-6, IL-12, and IL-10 were evaluated by 7900 HT fast Real-Time PCR System, (Applied Biosystem, Foster City, CA, USA) with SYBR Green PCR Master mix (EuroClone). Gene expression was quantified by the 2−ΔΔCt method and normalized against 𝛽-actin used as the internal reference gene. Results were expressed as fold changes versus control. Primers used for RT-qPCR are reported in Table S1.

Quantification of Antioxidant Gene Expression in Chicken Intestinal Tissue

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total RNA was extracted from chicken instestinal tissue and conserved in RNA later, by using a Quick-RNA MiniPrep plus kit (Zymo Research, Irvine, CA, USA) following the procedure described by the manufacturer. The concentrations of RNA samples were then quantified by using the NanoDrop 2000 Spectrophotometer (ThermoFisher, USA).
cDNA were synthesized by exploiting the Wonder RT-cDNA Synthesis Kit (Euroclone, Milan, Italy) and amplified by polymerase chain reaction (PCR) in presence of specific primers (Table 1) for SOD, CAT, and β-actin was used as house-keeping gene. The PCR mixture was composed by 1.5 U of a recombinant thermostable DNA polymerase (Wonder Taq Hot Start; Euroclone, Italy), 0.4 μM of each primers and a reaction buffer containing 5 mM dNTPs, 15 mM MgCl2, stabilizers and enhancers. The amplification was obtained by applying the following thermal program: 95°C for 1 min followed by 30 cycles at 95°C for 15 sec, Tm (melting temperatures reported in Table 1) for 15 sec, 72°C for 30 sec with a final extension at 72°C for 7 min. The PCR products were resolved on 1% agarose gel and the quantitative analysis of visualized spots was performed by using the Gel Doc 2000 software (Bio Rad Laboratories, Hercules, CA, USA).

Quantification of MerTK and ADAM9 Genes

Check if the same lab product or an alternative is used in the 5 most similar protocols
RNA was extracted from ARPE-19 cells cultured using an RNA/DNA/Protein Purification Plus Kit (Norgen Biotek Corp., Thorold, ON, Canada) according to the manufacturer’s instructions. The amount and quality of the RNA were determined spectrophotometrically. RNA samples with A260/A280 values of at least 2.0 were used for further analysis. Reverse-transcription of 1 µg of RNA to cDNA was performed using Wonder RT-cDNA Synthesis kit (Euroclone, Milan, Italy). Expression levels of the target genes MerTK (Applied Biosystems, Monza, Italy, assay ID: Hs01031968_m1) and ADAM9 (Applied Biosystems, Monza, Italy, Hs00177638_m1) were measured by qRT-PCR amplification, performed using Luna Universal Probe qPCR Master Mix (New England Biolabs, NEB, Ipswich, MA, USA) in an ABI PRISM 7900 HT Fast Real Time PCR System (Applied Biosystems, Monza, Italy). All reactions were performed in triplicate with the following qRT-PCR run protocol: initial denaturation (95 °C, 1 min), denaturation (95 °C, 15 s), and extension (60 °C, 30 s) repeated 43 times (95 °C, 15 s and 60 °C, 1 min). Gene expression was normalized using β-Actin and GAPDH as control genes (β-Actin assay ID: Hs01060665_g1, GAPDH assay ID: Hs02758991_g1, Applied Biosystems, Monza, Italy). Comparisons of gene expression were done using the 2−ΔΔCt method [22 (link)].

Quantitative Analysis of Gene Expression in SH-SYS5 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
SH-SYS5 cells were seeded and treated as described above. Then, cells were trypsinized and counted. A total of 5 × 106 cells was centrifuged and washed twice with phosphate-buffered saline (PBS). Total RNA was isolated using a RNeasy Mini kit (Qiagen, Hilden, Germany), according to the manufacturer’s protocol. RNA was quantified using a NanoDrop spectrophotometer (Thermo Fisher Scientific, Waltham, MA, USA), and integrity was checked on a 2% agarose gel. A quantity of 1 µg of RNA was employed to generate cDNA using the Wonder RT – cDNA- Synthesis Kit (EuroClone, Milano, Italy). cDNA was used to analyze the levels of transcripts by quantitative real-time PCR (qRT-PCR). The Tli RNase H Plus (Diateh labline, Ancona, Italy) and the LightCycler 2.0 instrument (Roche, Basel, Switzerland) were employed. The first gene analyzed was the house-keeping gene actin, and its CT values were used as standards in the ΔΔCT method of results analysis. cDNA samples from SH-SYS5-treated cells were compared to control cells. Samples were analyzed at least in triplicate and the Student’s t-test was used to verify the significance of results (a p-value less than 0.05 was considered significant). Primers were purchased from Sigma-Aldrich, and their sequences and conditions are listed in Table 1.

Total RNA was isolated using the Trizol (ThermoFisher Scientific), according to the manufacturer’s protocol. RNA integrity was confirmed through agarose gel electrophoresis, and RNA concentration and purity were determined with a Nanodrop 1000 spectrophotometer (Thermo Fisher Scientific). RNA was reversed transcribed using the Wonder RT cDNA Synthesis kit (Euroclone, Italy). The expression of ET-1, CTGF, CYR61, ANKRD1, E-cadherin, N-cadherin, vimentin, ZEB1, and cyclophilin-A mRNA was evaluated by using Luna Universal qPCR Master Mix (New England Biolabs, USA) on QuantStudio 6-Flex (Thermo Fisher Scientific), according to the manufacturer's instructions. The mRNA expression levels were determined by normalizing to cyclophilin-A mRNA expression and expressed as relative mRNA level (2^ΔΔct). Data are presented as means ± SD. Primer sequences are provided in Additional file 2: Table S2.

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.
