Pcr primers

Manufactured by Macrogen
Sourced in Italy, Canada

PCR primers are short DNA sequences used in the Polymerase Chain Reaction (PCR) process to amplify specific regions of DNA. They serve as the starting points for DNA synthesis, initiating the replication of targeted genetic material.

Molecular Profiling of Dried Specimens

Genomic DNA was extracted from tissue of dried specimen or fresh tissue preserved in CTAB, using a CTAB isolation procedure adapted from Doyle and Doyle (1990) . Portions of the genes atp6, cox3, rpb2, and tef1 were amplified by polymerase chain reaction (PCR). The primer pairs ATP6-1M40F/ATP6-2M (Raspé et al. 2016 (link)), COX3M1-F/ COX3M1-R (Vadthanarat et al. 2019b (link)), bRPB2-6F/bRPB2-7.1R (Matheny 2005 (link)), and EF1-983F/EF1-2218R (Rehner and Buckley 2005 (link)) were used to amplify atp6, cox3, rpb2, and tef1, respectively. PCR products were purified by adding 1 U of exonuclease I and 0.5 U FastAP alkaline phosphatase (Thermo Scientific, St. Leon-Rot, Germany) and incubated at 37 °C for 1 h, followed by inactivation at 80 °C for 15 min. Standard Sanger sequencing was performed in both directions by Macrogen with PCR primers, except for atp6, for which universal primers M13F-pUC(-40) and M13F(-20) were used. For tef1, additional sequencing was performed with two internal primers, EF1-1577F and EF1-1567R (Rehner and Buckley 2005 (link)).

Total DNA extraction from approximately 50 mg of 10-day fresh mycelium was performed using commercial DNA isolation kits following the manufacturer’s protocol. The PCR amplification of the glyceraldehyde-3-phosphate dehydrogenase (gapdh) region was carried out using gpd1 and gpd2 [32 (link)]. The amplification of RNA polymerase’s second largest subunit (rpb2) region was performed using RPB2–5F2 [33 (link)] and RPB2–7cR [34 (link)]. The Alternaria major allergen gene (Alt-a 1) region was amplified using primers alt-for and alt-rev [33 (link)]. The PCR components and amplification conditions were obtained as described by Woudenberg et al. [30 (link)]. The amplified amplicons were sequenced in both directions using PCR primers at Macrogen (South Korea) following the manufacturer’s instructions. The newly generated sequences in this study were deposited in the GenBank database (Table S1).

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.
