As a certified specialist in the provision of phosphoramidites and reagents for oligo synthesis, both direct to research groups and to oligo manufacturers, Link Technologies Ltd has observed a significant increase in requests for vitamin-modified oligo precursors, following on from the increasing use of vitamin-modified oligonucleotides in life science research. The growing interest in such compounds is reflective of the current buzz that surrounds research into the enhanced targeting and delivery of nucleotide-based treatments. Such research is vital for the therapeutic industry, wherein accurate targeting and effective uptake of pharmaceutical compounds is essential, not only for positive medicinal value but also to avoid undesirable, potentially dangerous side effects.

For example, researchers have recently highlighted the value of utilizing vitamin-modified oligonucleotides, such as those containing tocopherol, to facilitate oligonucleotide transport across cell membranes. The sourcing of reliable and pure modified phosphoramidite precursors for oligo synthesis will prove an important step in the production of such therapeutics, for use in gene therapy, RNA-induced gene silencing and further academic research.

The rise in demand for modified oligos is not only concurrent with the wealth of research in the drug delivery sector, but also with the progression of promising early-stage drug development into phased clinical trials. Such commercial progressions are utilizing increasing quantities of these chemically-altered oligos and, as such, Link Technologies has witnessed a rise in order quantities of the constituent modified phosphoramidites, to the scale of kilogram and beyond.

Dr Catherine McKeen, Technical Manager at Link Technologies, commented, “As a company dedicated to the provision of quality molecular tools, Link Technologies has the expertise and capacity to rapidly upgrade a product from small scale generation to production in kilogram quantities, as and when commercial progression dictates. Link Technologies can uniquely offer researchers supply and support throughout the entire research and testing lifetime of a Link product, omitting the need to change suppliers and thus eliminating any associated risk with product variation.”

The range of phosphoramidite modifications available is large and growing, fuelled in part by the extensive research and optimization programs being undertaken at suppliers such as Link Technologies. With over 20 years’ experience in the manufacture of modified phosphoramidites and solid supports, Link Technologies continues to build good relationships with Contract Manufacturing Organizations (CMOs); partnering and providing expertise for the product journey, from research compound to commercial reagent. This proactive approach not only assists the development of the chemical process but also allows Link Technologies to recognize and react to early indicators of future product demand, ensuring that they remain on top of trends to meet research needs.

Genome AnalysisGenomics, the study of genomes, includes functional genomics, evolutionary genomics and comparative genomics. There are many genomic technologies such as DNA sequencing of whole genomes, computational biology and bioinformatics. DNA and nucleic acids must be isolated and concentrated from cells for analysis with kits, automated analyzers and software. Other useful technologies for studying genomics include PCR, microarrays and electrophoresis.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.
