  • Patent number: 6028172
    Abstract: A solid phase peptide synthesis reactor system and method of operating the reactor are provided. The reactor system includes a basket rotatable about an axis within a housing and a receiver which delivers fluid to, and collects fluid from, the housing. The basket has a perforate side wall against which a resin cake for the peptide synthesis is formed. The reactor and receiver form a loop or circuit through which solutions are circulated. The circulation of the solutions prevents the reactor from flooding so that the basket will not be submerged in solution and allows for the use of less liquid. Thus greater amino acid concentrations may be used. The method includes forming a resin cake of uniform depth on the wall of the spinning basket and spraying the solutions against the resin cake while spinning the basket. The solutions will pass through the resin cake and drain to the receiver to be circulated or recycled through the system or discharged from the system.

  • Patent number: 5425924
    Abstract: A compact fixed-bed catalytic reactor containing a plurality of staggered partitioning plates inside a reactor vessel to form a folded reaction path. The reactor is substantially rectangular in shape and each of the partitioning plates is held inside the reactor by a frictional force between the partitioning plate and the inner wall of the reactor vessel while one side thereof, being shorter than the width of a corrsponding inner side the reactor, forms an opening allowing the passage of reactant therethrough. The partitioning plates contain a plurality of fingers to further secure the same in place and prevent horizontal movement thereof. The present invention allows a box-like catalytic reactor to provide the advantages of a fixed-bed tubular reactor, while maintaining a desirable spacial compactness and lowering the construction cost.

  • Patent number: 5350681
    Abstract: The present invention discloses a method for the enzymatic synthesis of a peptide. A protected peptide having a C-terminal carboxylate group or a protected, N-acyl amino acid having an alpha carboxylate group is reacted with a protected peptide having an N-terminal ammonium group or a protected amino acid having an alpha ammonium group in the presence of a condensation enzyme under conditions in which the carboxylate group and the ammonium group condense to form a protected, uncharged, peptide product. This peptide product is transported across a water-immiscible hydrophobic phase into an aqueous product phase and prevented from back diffusing across the water-immiscible hydrophobic phase. The peptide product can be converted, chemically or enzymatically, to a charged species that cannot back diffuse across the water-immiscible phase into the aqueous reaction phase.

  • Patent number: 5186902
    Abstract: A CO.sub.2 gas generator for a utilization device is located in a housing and chemically generates CO.sub.2 from a chemical reaction between two reagents contained within a common container. The reagents are located in different chambers of the container with a CO.sub.2 accumulation region being included in one of the chambers. A reference pressure source of a predetermined pressure forces the two reagents into contact with each other when the pressure of gas in the CO.sub.2 accumulation region is less than the predetermined pressure whereupon CO.sub.2 is generated in one of the chambers. An output conduit in fluid communication with the CO.sub.2 accumulation region is provided to withdraw the generated gas from the generator. As the CO.sub.2 is withdrawn, the gas pressure drops permitting more mixing of the reagents. When the CO.sub.2 pressure becomes equal to or higher than the predetermined pressure applied by the reference pressure source, the reagents become separate again and gas generation ceases.
