  • Patent number: 5424402
    Abstract: A kit and method of non-destructively radiolabelling a biomolecule substrate by halogenation, including the steps of: a) reacting a secondary amine with a chlorinating agent to produce an N-chloro secondary amine, (b) reacting the N-chloro secondary amine with a salt of a radiolabelled halogen to produce a radiolabelled halogenating agent, (c) reacting a solution of the biomolecule substrate with the radiolabelled halogenating agent, and (d) recovering a radiohalogenated biomolecule from the reaction of step (c). The kit and method allow for more complete iodination with a lessening of side reactions such as decomposition of the biomolecule substrate to be labelled.

  • Patent number: 5412075
    Abstract: The method for preparing high grade gelatin with a specific methionine content and with reduced methionine variability from batch to batch and within a single extraction includes controlling the amount of and variability of oxidant present during processing of bone stock into gelatin. Such controls include control of oxidant concentration and range in process water, control of volume of process water used in gelatin-making process and restriction of the range of gelatin extracts used in the product gelatin. Once the aim level of oxidant has been set, the total range of oxidant around the set point should be less than 220 meq per 100 kg dry bone.

  • Patent number: 5407912
    Abstract: The present invention is directed to a stabilized keyhole limpet hemocyanin (KLH) composition in which (i) its intact non-degraded subunit is approximately 400,000 in molecular weight based on SDS-PAGE analysis; and (ii) are contained at least about 50% didecameric or higher KLH multimers, based on sedimentation-equilibrium and/or sedimentation-velocity ultracentrifugation analyses. The KLH composition is stabilized at 4.degree. C. by dissolving and storing it in an isotonic buffer preferably containing calcium and magnesium. It is critical that the KLH not have been frozen or lyophilized during its preparation or storage. The KLH composition demonstrates enhanced immunogenic activity, particularly enhanced anti-tumor activity, which is reduced if the KLH is frozen or lyophilized. The KLH composition of the present invention exhibits enhanced anti-tumor activity in a murine bladder tumor model and thereby represents a new and useful anti-tumor immunotherapeutic agent.
