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.

摘要:The present invention provides a composition and process for removal of colours and inhibitors from tissues to isolate RNA. Particularly, this invention relates to a composition and the method to remove the soluble substances that otherwise would impart colour to the ribonucleic acid (RNA) preparations or would inhibit down stream applications including synthesis of complementary DNA (cDNA) and polymerase chain reaction using RNA as one of the substrates. Reported protocols till date can isolate RNA, but the isolated RNA is not suitable for downstream processes such as RT-PCR due to presence of colours and the associated interfering agents. None of the protocols describe a simple and quick method for removal of these interfering chemicals.

摘要:The present invention discloses a polypeptide and application thereof. By modifying oxyntomodulin (OXM), hybridizing OXM with a peptide sequence of Exenatide, including enabling the polypeptide to be resistant to DPP-4 enzyme degradation through amino acid modification, and conjugating fatty acid chains at the same time, an OXM hybrid peptide having longer pharmacologic action time and better weight losing effects is obtained. Synthesis of a target polypeptide is fast realized by an orthogonal protection strategy solid-phase synthesis method, and a crude product is purified and freeze-dried to obtain the OXM hybrid peptide.

摘要:A zinc oxide microcrystalline fiber and a low-temperature template-free hydrothermal synthesis method therefor. The method comprises: step 1. a divalent zinc salt reacts with a strong base in water to obtain a first transparent solution containing Zn(OH)4 2-ions, the divalent zinc salt being selected from one or more of zinc chloride, zinc acetate, and zinc nitrate; and step 2. the first transparent solution reacts in a reactor having a non-sticky surface, in the presence of a surfactant and at a temperature does not exceeding 100°C to obtain a zinc oxide microcrystalline fiber, the surfactant being selected from one or more of dodecyl sulfate and polyoxyethylene octyl phenyl ether having 9 or 10 oxyethylene units. The method for synthesizing a zinc oxide microcrystalline fiber is relatively simple, can avoid the use of expensive equipment such as an autoclave, and does not require any template, thereby greatly reducing the production costs of a zinc oxide microcrystalline fiber, and facilitating the large-scale production of the zinc oxide microcrystalline fiber and wide application thereof in daily life.
