Linearization by pcr
NettetThere are two strategies for generating transcription templates: PCR amplification and linearization of plasmid with a restriction enzyme (Figure 2). Which one to choose will depend on the downstream application. In general, if multiple sequences are to be made and transcribed in parallel, ... Nettet17. apr. 2012 · Inverse fusion PCR cloning (IFPC) is an easy, PCR based three-step cloning method that allows the seamless and directional insertion of PCR products into virtually all plasmids, this with a free choice of the insertion site. The PCR-derived inserts contain a vector-complementary 5′-end that allows a fusion with the vector by an …

NettetThe outbreak of coronavirus disease 2024 (COVID-19) in Wuhan, China, was caused by a novel coronavirus (CoV), named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The rapid detection of viral nucleic acids is critical for the early identification of infected cases. We have developed two TaqMan real-time reverse transcription-PCR …
NettetThis protocol describes the synthesis and purification of RNAs using plasmid DNA or PCR-amplified DNA as a template. This procedure should give NTP-free, full-length RNA for all sizes of RNA. This protocol is derived from Milligan and Uhlenbeck, the classic paper on T7 transcription reactions, with … Nettet12. apr. 2024 · For oocyte expression, plasmid DNA was linearized using Not1-HF (NEB, R3189) for 2 h at 37 °C. Linearized DNA was purified using a PCR purification Kit (Qiagen, 28104) and eluted in 30 ml RNase ...
Nettet8. mar. 2024 · If you are using PCR to create the insert or to amplify a linearized vector, PCR primers lacking 5’-phosphates are useful to reduce the background of the re-circularized vector during cloning. Likewise, enzymatic methods can be used to remove phosphates by treating the DNA fragments with alkaline phosphatase.
