  • Patent number: 6649753
    Abstract: This invention relates to the production of new & stable salts of S-adenosyl-L-methionine SAMe). The source of SAMe used in the salt formation is from chemical process wherein stereoselective methylation of S-adenosyl-L-homocysteine is achieved. The process for the salt preparation is simple, efficient & reproducible on large scale. The new salts were found to be stable at accelerated temperature for minimum 3 months.

  • Patent number: 6646118
    Abstract: The present invention relates to a support system for solid phase synthesis of oligomers, such as oligonucleotides, wherein the starting compound is bound to the support via a disiloxyl linkage. Furthermore, the invention relates to a method for synthesis of oligonucleotides on a solid support. The support system comprises a stable disiloxyl linkage providing high nucleoside loadings to the support and the method allows convenient non-laborious oligomer synthesis.

  • Patent number: 6642373
    Abstract: The present invention relates to improved methods for the preparation of nucleoside phosphoramidites and oligonucleotides. In one aspect, the methods of the invention are used to prepare phosphitylating reagents using pyridinium salts as activators. In a further aspect, the methods of the invention are used to prepare internucleoside linkages using activators which include at least one pyridinium salt and at least one substituted imidazole. In a further aspect, methods are provided preparation of internucleoside linkages between nucleosides having 2′-substituents using imidazolium or benzimidazolium salts as an activator. In a further aspect, methods are provided preparation of internucleoside linkages between nucleosides having bioreversible protecting group that confers enhanced chemical and biophysical properties, without exocyclic amine protection, using imidazolium or benzimidazolium salts as an activator.

  • Patent number: 6632941
    Abstract: Chitin is extracted from the shells of exoskeletal animals such as crab, shrimp, crayfish, and lobster, by a primarily physical process comprising the step of cutting the shells in a wet state to approximately uniform particles. The resultant mass is then diluted and mixed to form a pumpable slurry. The slurry is separated to remove most unwanted materials, after which the particle size of the concentrated chitinous residue is further reduced. The once-washed, finely-cut chitinous slurry is again separated, resulting in a chitin end product.

  • Patent number: 6596856
    Abstract: Nucleic acid labeling compounds containing heterocyclic derivatives are disclosed. The heterocyclic derivative containing compounds are synthesized by condensing a heterocyclic derivative with a cyclic group (e.g. a ribofuranose derivative). The labeling compounds are suitable for enzymatic attachment to a nucleic acid, either terminally or internally, to provide a mechanism of nucleic acid detection.

  • Patent number: 6548659
    Abstract: Process for enriching the organic nitrogen content of commercial scale quantities of cellulosic materials which includes the steps of: a) placing substantially dry or unwetted cellulosic material in a pressurizable reactor; b) injecting an ammonia or ammonia-forming nitrogen solution into the reactor until the cellulosic material is approximately submerged; c) setting the temperature in the reactor to maintain a liquid temperature between about 80 and 200° C.; d) pressurizing the reactor to at least 750 psi; e) maintaining the temperature and pressure in the reactor for a period of time sufficient for the organically bound nitrogen content of the cellulosic material to exceed about 1.5%; and f) drying the cellulosic material to a moisture content sufficiently low to arrest microbial activity.
