Antisense oligonucleotides: Modulation of gene expression with modified oligos
25 Jan 2024Traditional antisense oligonucleotides (ASO)-based gene modulation (usually synonymous with silencing or downregulation of gene expression, but it can be used to improve gene expression and, in at least one particular case, it was shown to lead to upregulation of gene expression) targets mRNA and can take place in either the nucleus or the cytoplasm. Gene silencing should be simple, but there are many considerations to take into account for a successful ASO design. In this application note, Merck presents ASOs for modulation of gene expression. The note highlights common types of ASO modification and provides considerations for different types of experiments.

OligonucleotidesOligonucleotides are small nucleic acid polymers, usually less than 20 bases in length. Oligonucleotides can be made via enzymatic cleavage or more commonly by chemical synthesis with polymerases. Their use includes FISH, southern blots, microarrays and as primers in PCR. High fidelity synthesis kits and detection systems are available for easy production and detection, respectively.Gene Expression and Molecular CloningMolecular cloning is a set of techniques that utilizes vectors to transfer recombinant DNA into host cells and is an essential tool for investigating the expression of genes and proteins in bacterial or mammalian cells. A variety of vectors optimized for gene cloning and expression in a range of host organisms are available, alongside competent cells for genetic replication. Here, you can explore a range of molecular tools, high-quality genomic and cDNA libraries, premade clones, transformation and transfection reagents and mutagenesis or gene expression detection assays and expression arrays. Find the best gene expression and molecular cloning products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.RNA InterferenceRNA interference (RNAi) uses siRNA or miRNA for transcriptional silencing, gene knockdown and regulation of gene expression. RNAi requires chemical synthesis, introduction of DNA vectors into cells, an assay of RNAi effects and RNAi quantification or analysis. Consider target sequence selection, reagent preparation, controls, high specificity and effectiveness and low non-specific gene knockdown.RNARNA is a nucleic acid that plays a key role in gene expression and protein synthesis. It serves as a messenger between DNA and ribosomes, carrying genetic instructions to produce proteins. Advances in RNA-based therapies, such as mRNA vaccines and gene editing, have revolutionized treatment strategies for genetic disorders and infectious diseases. Explore RNA research tools and therapies in our peer-reviewed product directory; compare products, check customer reviews, and get pricing directly from manufacturers.Gene EditingGene editing is the precise alteration to an organism's DNA, with CRISPR being the most well-known technique. It is used in a wide range of applications, including the development of disease models and gene therapy, and crop improvement.
