Gateway recombination cloning technology

Manufactured by Thermo Fisher Scientific
Sourced in United States, United Kingdom

Gateway recombination cloning technology is a molecular biology tool that enables the rapid and efficient transfer of DNA sequences between different vector systems. It utilizes site-specific recombination to facilitate the movement of DNA fragments, allowing for the creation of various expression constructs. The core function of this technology is to provide a streamlined method for DNA manipulation and gene expression studies.

Conditional Expression of hADAR2 in Yeast

Check if the same lab product or an alternative is used in the 5 most similar protocols
The relevant plasmids used in this study are presented in Table S1. The Gateway recombination cloning technology (Invitrogen, Waltham, MA) was used to clone the hADAR2 into the URA3 marked plasmid (pYES2-DEST52 Gateway destination vector [catalog #12286-019]; Thermo Fisher Scientific, Waltham, MA). The URA3 marker was later swapped with the LEU2 marker to create BSB641. This plasmid enables the conditional expression of the hADARs in yeast, under a galactose-inducible promoter (GAL1p-hADAR2).
The plasmid carrying the URA3 reporter gene (BSB656) was created using in vivo homologous recombination in yeast, by co-transforming the yeast URA3 gene (including its 5′ promoter region and 3′ UTR) into a linearized HIS3-marked plasmid (pRS31349 (link)) digested with XhoI/XbaI. In vivo homologous recombination was used to insert the target and reverse complement “tail” sequences (shown in Table S2) by linearizing BSB656 with either EcoRI (target insertion) or BamHI (“tail” insertion). Site-directed mutagenesis was used to insert the EcoRI (right before the URA3 start codon) and BamHI (right after the URA3 stop codon). The target and “tail” insertions were validated by PCR and Sanger sequence using OSB2366/OSB207 and OSB1202/OSB502, respectively (Table S3).

For cloning of human IL-4 complimentary DNA into the lentiviral vector pGLTR-X-PURO, the Invitrogen Gateway Recombination Cloning Technology (Life Technologies Ltd) was used. pGLTR-X-PURO was kindly provided by Dr Stephan Geley.59 (link) IL-4 was re-cloned from pcD-human-IL-4(clone 125) (ATCC, Rockville, MD, USA) using a pair of specific primers (5′-CAAAAAAGCAGGCTCCATGGGTCTCACCTCCCAAC-3′ and 5′-CAAGAAAGCTGGGTCTCAGCTCGAACACTTTGAATATTTC-3′), which incorporated specific overhangs for the gateway reaction into the pDONOR221. The pDONOR221-Escherichiacoli-β-glucuronidase (GUS) was used for the control vector pGLTR-GUS-PURO and was provided by Invitrogen (Life Technologies Ltd).

Fluorescent Protein Localization in Plants

Check if the same lab product or an alternative is used in the 5 most similar protocols
Sequences encoding full-length and truncated (Trp-rich regions only) ESV1 and LESV protein versions were amplified using constructs from (14 (link)) as templates. The resulting PCR products were first cloned into the pDONR221 vector and subsequently recombined into pB7WGY2 (for the truncated versions; in-frame with N-terminal sequence encoding the Arabidopsis Rubisco small subunit chloroplast transit peptide followed by sequence encoding YFP) or pB7YWG2 (for the full-length versions; in-frame with a C-terminal sequence encoding YFP) via gateway recombination cloning technology (Invitrogen), as described previously (45 (link)). The resulting constructs were transformed into Agrobacterium tumefaciens, infiltrated into tobacco (N. benthamiana), and the fluorescence was imaged as described previously (14 (link)).

Construction of a Fusion Transgene for Metabolic Engineering

Check if the same lab product or an alternative is used in the 5 most similar protocols
The coding DNA sequences of Ta1SST and Ta6SFT [13 (link)] were designed as one transcriptional fusion sequence in silico (Vector NTI 11, Thermo Fisher Scientific, USA). This fusion sequence was regulated by a TaRbcS promoter and terminator [19 (link)] (Fig. 1a). The transgene sequence (TaRbcS-p_Ta1SST:Ta6SFT_TaRbcS-t) was synthesized using the Invitrogen™ GeneArt™ Gene Synthesis service (Thermo Fisher Scientific, USA), and was then transferred into the transfer DNA (T-DNA) region of a binary expression vector using GATEWAY® recombination cloning technology (Invitrogen, USA). The T-DNA region of the binary vector also contained a selectable marker cassette (OsActin-p_bar_CaMV35s-t) that comprised a synthetically constructed bar gene [50 (link)], that encoded for phosphinothricin acetyltransferase (PAT), and regulatory sequences from the rice actin promoter and Cauliflower Mosaic Virus Terminator (Fig. 1b). The final T-DNA vectors were confirmed using Sanger sequencing.

Cloning and Stable Transformation of OsISA Genes

Check if the same lab product or an alternative is used in the 5 most similar protocols

OsISA1 and OsISA2 coding sequences were amplified by PCR using attB-site containing primers (Table S1). The templates were pGEM-T Easy vectors containing OsISA1 and OsISA2 cDNA sequences [25] (link). The PCR fragments were cloned into pDONR 221 via the BP reaction of the Gateway recombination cloning technology (Invitrogen, LuBioScience GmbH. Lucerne, Switzerland). After sequence conformation, inserts were cloned into the plant vector pB7WG2 [27] (link) using the Gateway LR reaction. Stable Arabidopsis thaliana transgenic lines were generated through Agrobacterium tumefaciens-mediated transformation using the floral dip method [34] (link). Independent transformants were selected on soil by spraying two-week-old plants with 0.1% (v/v) BASTA herbicide.

To generate the TRIM8 dTAG cell lines, TC32 and TC71 cells were co-infected with FKBP12F36V-2XHA tagged TRIM8 and sgRNAs targeting TRIM8 to replace endogenous TRIM8 with FKBP12F36V-2XHA tagged TRIM8.

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.
