Abstract: A lipid antigen found in colon, breast, lung, ovarian and pancreatic human adenocarcinomas identified by reactivity with human monoclonal antibody 81AV78, and the use of the antigen in vaccines.
Abstract: A novel bifunctional macrocyclic chelating agent useful for attaching metal ions to proteins, polypeptides and other polymers. These reagents are unique in their ability to bind a variety of metal ions and to yield a high metal ion concentration per protein molecule. Protein metal chelates thus obtained will have useful radiophysical, chemical, fluorescent, photochemical and magnetic properties suitable for biomedical applications.
Abstract: A method for in-vivo targeting a functional moiety in a patient by administering a targeting moiety coupled to an affinity component, wherein the targeting moiety has affinity for binding sites in a target area, and administering a binding partner to the affinity component coupled to a functional moiety to localize the functional moiety in the target area. Preferably the targeting moiety is an antibody and the functional moiety is a radiometal when performing in vivo imaging or therapy. The affinity component may be a novel methotrexate analog.

Abstract: A device and method for detecting microorganisms in a specimen by culturing the specimen in a sealable specimen container with a culture medium and detecting microorganisms in the specimen-by measuring changes in pressure within the container caused by their metabolic activity during culturing. Pressure changes are measured using a sensor having a deformable section in communication with the container and a piezoelectric apparatus, such that the piezoelectric apparatus is deformed by changes in pressure within the specimen container and an electrical signal is produced by the deformation. The electrical signal is processed to detect any change in the rate of change of pressure, and thus detect the growth of microorganisms.

Abstract: A method and apparatus for a liquid level sensor control circuit of a bioassay apparatus for controlling a position of a sampling probe with respect to a surface of a liquid in a container. The apparatus includes a sampling probe, an oscillator circuit coupled to the sampling probe for producing a first output signal having a constant frequency, a comparator coupled to the oscillator circuit for comparing the amplitude of the first output signal to a first reference amplitude and for producing a change signal when the amplitude of the first output signal changes with respect to the reference amplitude, and a controller responsive to the change signal for controlling the position of the sampling probe with respect to the surface of the liquid.
Abstract: A new series of bifunctional chelating agents useful for attaching metal ions to proteins, polypeptides and other polymers and methods for their preparation are described. These reagents are unique in their ability to bind a variety of metal ions and to yield a high metal ion concentration per protein molecule. Using these methods polymeric analogs of these bifunctional chelating agents called Starburst ligands can also be obtained. Protein metal chelates thus obtained will have useful radiophysical, chemical, fluorescent, photochemical and magnetic properties suitable for biomedical applications.
Abstract: This invention relates to a method of cancer therapy for treating human patients with resectable solid tumors to inhibit recurrence and formation of metastases, comprising surgically removing tumor tissue from a human cancer patient, treating the tumor tissue to obtain tumor cells, irradiating the tumor cells to be viable but non-tumorigenic, preparing a vaccine comprising about 10.sup.7 viable but non-tumorigenic tumor cells per dose and injecting the vaccine intradermally into the human patient after the patient's immune system has recovered from surgery.
