KN269544.1) spanning from bp 2 of exon 11 to the 36th nucleotide of exon 12 of the llama CSN1S1 gene was amplified by using the primers (forward) 5′-AAGTTGTTTCCAGTACCAC-3′ and (reverse) 5′-TTGGGAGGGCATATCTT-3′, as well as the same PCR mixture conditions reported by Pauciullo and Erhardt (2015) (link). Thermal conditions were 95°C for 4 min, 35 cycles at 95°C for 30 s, 60°C for 30 s, 72°C for 20 s, with the final extension at 72°C for 5 min. Product specificity was confirmed by Midori Green Advance (Nippon Genetics, Düren, Germany) stained by 1.5% agarose gel electrophoresis.
Ten microliters of each PCR amplification was digested with 5 U of MaeII endonuclease (5′-A↓CGT-3′; New England Biolabs, Ipswich, MA) overnight at 65°C.

Check if the same lab product or an alternative is used in the 5 most similar protocols
To remove any DNA contamination, 5 µl (1 U µl−1) DNAase I and 5 µl DNAse I buffer were added to each 50 µl RNA sample followed by incubation at 37 °C for 30 min. DNAse I was then inactivated by adding 5 µl EDTA (50 mM) and incubation at 65 °C for 10 min. Eventually, the RNA samples were checked for DNA contamination by PCR analysis using actin gene specific primers: 5′-AGTACGTACGTGTTGGCCATG-3′ (actin forward primer) and 5′-AGTACGTACGTGTTGGCCATG-3′ (actin reverse primer). For a PCR, 2 µl of RNA sample were mixed with 1 µl 10 µM of each forward and reverse primer, respectively, 5 µl 10× reaction buffer (Axon), 4 µl 25 mM MgCl2, 1 µl of a mixture of 10 mM (each) dNTP, 0.5 µl (5 U µl−1) Taq polymerase (Axon) and 35.5 µl ddH2O to a final volume of 50 µl. PCR reactions were initiated by DNA denaturation for at 94 °C for 1 min, followed by 35 cycles of denaturation at 94 °C for 1 min, primer annealing at 50 °C for 45 s and elongation at 72 °C for 1 min. Final elongation was performed at 72 °C for 5 min. Genomic DNA of C. pomonella was used for positive- and water for negative-control reactions.

The PCR reaction was standardized with 2.5 µl of 10x Shark buffer (DNA Gdańsk), 2.5 µl of MgCl2 (25mM) (DNA Gdańsk), 3 µl of dNTP (2 mM) (nzytech, Portugal), 30 pmol of each primer ERIC1R and ERIC2, 1U of Hypernova DNA polymerase (Blirt), 3 µl of template DNA, and nuclease‐free water up to a final volume of 25 µl. The amplification cycles included initial denaturation at 95°C for 5 min, followed by 40 cycles of denaturation at 95°C for 60 s, annealing at 40°C for 90 s and extension at 72°C for 60 s with a single cycle for final extension at 72°C for 7 min. Primer sequences are summarized in Table S4.
Ten microlitres of PCR products were electrophoresed on a 1.5% agarose gel in the presence of Midori Green Advance (Nippon Genetics), at 120 V for 120 min. The results were read using the Quantum ST5 Gel Documentation System (Vilber).

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.
