We have developed a system for the induction of marker-free mutation of Bacillus subtilis. The system features both the advantages of the use of antibiotic-resistance markers for mutant selection, and the ability to efficiently remove the markers, leaving unmarked mutations in the genome. It utilizes both a selective marker cassette and a counter-selective marker cassette. The selective marker ...
conclusions the results of this study demonstrated that the tpasp-padre-truncated orf2 gene cassette and the truncated orf2 gene in recombinant plasmids are successfully expressed in eukaryotic cells. the immunogenicity of the two recombinant plasmids with different formulations will be evaluated as a novel dna vaccine in future investigations. results sequence analysis and bioinformatics studi...
The kanMX4 resistance marker is widely used for Saccharomyces cerevisiae gene deletion and has been used to create a genome-wide deletion mutant collection. Transfer of PCR-amplified marker loci from collection mutants is a very efficient way of introducing mutations into other S. cerevisiae strains of interest. An important limitation of this strategy is that the kanMX4 marker is not easily re...
UNLABELLED Integrons are bacterial genetic elements able to capture and express genes contained within mobile gene cassettes. Gene cassettes are expressed via a Pc promoter and can be excised from or integrated into the integron by integrase IntI. Although the mechanisms of gene cassette integration and excision are well known, the kinetics and modes of gene cassette shuffling leading to new ge...
This work describes a self-contained, simple, disposable, and inexpensive gel capillary cassette for DNA amplification in near point of care settings. The cassette avoids the need for pumps or valves during raw sample delivery or polymerase chain reaction (PCR) amplification steps. The cassette contains capillary reaction units that can be stored at room temperature for up to 3 months. The curr...
BACKGROUND Fission yeast is one of the most commonly used model organisms for studying genetics. For selection of desirable genotypes, antibiotic resistance cassettes are widely integrated into the genome near genes of interest. In yeasts, this is achieved by PCR amplification of the cassette flanked by short homology sequences, which can be incorporated by homology directed repair. However, th...
Abstract Background To the best of our knowledge, manually production [ 177 Lu]Lu-FAPI radiopharmaceutical derivatives has been only described in literature. In this work, a fully-automated synthesis well designed for first time using commercially available module. addition to development an automated system with disposable cassette, quality control (QC) and stability studies were comprehensive...
The gene cassettes found in class 1 integrons are generally promoterless units composed by an open reading frame (ORF), a short 5' untranslated region (UTR) and a 3' recombination site ( attC). Fused gene cassettes are generated by partial or total loss of the attC from the first cassette in an array, creating, in some cases, a fusion with the ORF from the next cassette. These structures are ra...
Homologous recombination between closely related gene cassettes, such as aadA1 and aadA2, which are 89% identical, can create hybrid cassettes and hybrids of existing cassette arrays. A new cassette array, dfrA12-orfF-aadA8b, which was created by such a recombination event occurring within the aadA2 cassette in the dfrA12-orfF-aadA2 array, has been identified.
