摘要:The present invention relates to the technical field of oligonucleotide synthesis. Disclosed are the use of silicon dioxide microspheres in the synthesis of an ultra-long oligonucleotide and a method for synthesizing an ultra-long oligonucleotide, wherein the silicon dioxide microspheres have a specific surface area of less than 1 m2/g, and preferably, the silicon dioxide microspheres have modification groups on the surface. The method for synthesizing an ultra-long oligonucleotide comprises: performing a coupling reaction on a nucleoside phosphoramidite synthesis unit using the silicon dioxide microspheres having modification groups on the surface as carriers under coupling reaction conditions. The prepared carriers can be used to prepare an ultra-long oligonucleotide.

标题 :Formulations for the synthesis of paramagnetic particles and methods that utilize the particles for biochemical applications
发明人：UTERMOHLEN JOSEPH GERARD
权利人:UTERMOHLEN JOSEPH GERARD
摘要:A set of paramagnetic particles synthesized by co-precipitation methods wherein an alkaline hydroxide solution is mixed with a metal salt solution. The alkaline hydroxide features ammonium hydroxide, potassium hydroxide, sodium hydroxide, or mixtures thereof. The metal salt solution features at least one ferrous salt and at least one tetravalent metal salt selected from Group 4 elements of the Periodic Table. The concentration of the ferrous salt is equal to or greater than the concentration of the tetravalent metal salt. The paramagnetic particles may be used for bioprocessing via magnetic fields. Bioprocessing, for example, may include purifying, concentrating, or detecting biomolecules of interest (e.g., nucleic acids, carbohydrates, peptides, proteins, other organic molecules, cells, organelles, microorganisms, viruses, etc.), or other magnetic field-based processes common to applications in separation science, diagnostics, molecular biology, protein chemistry, and clinical practice.
