Abstract: The present invention relates to a method for isolating proteins from a solution containing the proteins. The invention also relates to a method for the chromatographic separation of proteins. The present invention also relates to crosslinked hydroxylic polymer particles functionalized with temperature-responsive copolymer, and to methods of preparing such particles.

Abstract: A method and composition for improving one or more indicators of bowel health or metabolic health in a mammalian animal. This comprises the delivering to the gastrointestinal tract of the animal an effective amount of an altered wheat starch in the form of or derived from the grain of a wheat plant. The proportion of amylose in the starch of the grain is at least 30%.

Abstract: A polymer comprising a conducting or semiconducting segment coupled to a polymer segment having an insulating polymer backbone, the polymer further comprising a RAFT functional group coupled to the polymer segment, wherein there is no RAFT functional group in between the conducting or semiconducting segment and the polymer segment.

Abstract: The purpose of this project was to isolate recombinant antibodies for diagnosis of very virulent infectious bursal disease virus (vvIBDV) in fixed tissues. Phage-displayed recombinant antibodies, comprised of the single chain variable fragment (scFv), were investigated. A previously made recombinant antibody library generated against vvIBDV was selected and screened for recombinant antibodies that reacted against vvIBDV in ELISA. A new library was constructed fom chickens immunized with fixed vvIBDV and also screened for recombinant antibodies against vvIBDV. Also, a previously identified recombinant antibody, known to react well with vvIBDV, was used to replace either the Vh or VI gene with corresponding fragments from a new library. The Vh and VI antibody genes were initially amplified effectively by PCR. No new recombinant antibody clones were isolated from the libraries generated against vvIBDV.

Abstract: The invention relates to the identification and isolation of polynucleotide molecules encoding a new class of protein insecticidal toxins which are produced by bacteria from the genera Xenorhabdus and Photorhabdus. The polynucleotide molecules may be incorporated into, for example, insect-specific viruses (including entomopox and nuclear polyhedrosis viruses), bacteria (including Gracilicutes, Firmicutes, Tenericutes and Mendosicutes), protozoa, yeast and plants for control of pest insects.

Abstract: Fumigation of grain in a storage facility having a plurality of grain silos or bins is effected from a single source of a gaseous fumigant. The single source of gaseous fumigant is connected to a gas supply duct through which a carrier gas flows. The gas inlet ports of the silos are also connected to the gas supply duct. The connection between each gas inlet port and the duct is provided with a respective valve and a respective orifice plate, the orifice or aperture of which is sized so that the pressure drop across the orifice plate into the silo is substantially greater than the pressure drop across any other component between the gas source and the silo. With this arrangement, the flow rate of gaseous fumigant through the grain-containing silos in the facility suffers only a minor perturbation when a valve between the duct and a silo is opened or closed. This minor perturbation can be readily compensated by maintaining the gas pressure in the duct at a constant value.

Abstract: A recombinant vaccine comprises a vaccine vector which incorporates a first nucleotide sequence capable of being expressed as all or a part of an antigenic polypeptide, together with a second nucleotide sequence capable of being expressed as all or a part of a lymphokine effective in enhancing the immune response to the antigenic polypeptide. The vaccine vectors include poxvirus, herpes virus or adenovirus, and the lymphokine may be an interleukin, tumour necrosis factor or gamma-interferon. The vaccine vector may express an antigenic polypeptide which is foreign to the host vector.

Abstract: A process for the agglomeration of powder or dust of alumina containing material (herein referred to as "alumina powder"), wherein an aqueous slurry of the alumina powder is formed, the slurry containing a sufficient quantity of an inorganic binder comprising a polymer form of a hydroxy salt of aluminum. The slurry is subjected to a spray drying operation to form agglomerated granules of the alumina powder, and the granules then are calcined at an elevated temperature for their consolidation. The alumina containing material comprises Al.sub.2 O.sub.3.nH.sub.2 O, wherein n is in the range of from 0 to 3.

Abstract: This invention concerns the delivery of anti-parasitic agents to ruminant animals. More particularly, the invention concerns delivery of such agents in a controlled manner to enable the agent to have maximum effect on the parasite for longer times than is possible with conventional formulations. The composition of the invention comprises a benzimidazole, macrocyclic lactone, organophosphate, salicylanilide/substituted phenol, tetramisole or pyrimidine anti-parasitic agent dispersed in a medium the solubility characteristics of which are such as to ensure that, following oral administration, controlled amounts of the anti-parasitic agent become available to the parasite, either directly or by absorption into the ruminant blood plasma, during passage of the composition through the rumen, the abomasum and the intestine.
