Abstract: The present invention relates to novel bispecific three-chain antigen-binding polypeptides and their preparation and use in the treatment and/or diagnosis of various diseases, and also relates to bispecific three-chain antibody-like molecules (TCAs) capable of activating immune effector cells and their use in diagnosis and/or treatment of various diseases.

Abstract: One embodiment relates to a fitness development system. The fitness development system generally comprises an exercise chamber and an object. The exercise chamber may comprise a base, an inclined floor, and one or more barriers. The base may define a substantially horizontal axis to support the exercise chamber, while the inclined floor may comprise an angle of inclination that defines a degree of separation of the inclined floor from the base, wherein the angle of inclination maximizes fitness development of an individual advancing the object up the inclined floor against a gravitational pull on the object. The barriers may substantially enclose the exercise chamber. The object may comprise a configuration enabling maximum fitness development of the individual advancing the object up the inclined floor.

Abstract: A method of preparing polyclonal immunoglobulin Fab fragments comprising cleaving immunoglobulin molecules, characterised in that the said cleavage is carried out on immunoglobulins in blood, serum or plasma in a closed, sterile environment.

Abstract: The present invention describes methods for screening or selecting novel proteolytic enzymes. These enzymatic functions can be selected from isolated chromosomal DNA libraries or from pools of mutagenized DNA encoding a proteolytic function. In particular, the selection method of the present invention, a phage gene is chosen that encodes a gene product necessary for the production of a phage. The phage carrying the modified gene is introduced into a host. Also, DNA libraries present within a cloning vector are introduced into host cells. The host cells are grown under conditions where the introduced libraries are expressed in the host cells. The presence of an enzymatic function capable of cleaving the target peptide is identified on the basis of production of infective phage.

Abstract: An immunogenic composition for raising antisera to a drug comprising immunologically active carrier protein to which is bound at least two types of hapten, each hapten comprising a drug molecule and, optionally, a bridging group, a method of raising antisera to a drug using said immunogenic composition, and a method of alleviating an overdose of a tricyclic depressant drug comprising an effective amount of antisera raised to an immunogen.

Abstract: Methods and kits are described for performing immunoassays. The kit includes a reaction cell having a microporous membrane and an absorbent capable of drawing liquid sample through the membrane. An applicator is provided for applying a small volume of the liquid sample to the membrane by contacting a port of the applicator to the membrane and allowing the sample to flow therethrough by capillary action. Analyte in the sample is immobilized, typically by immunoadsorption, and the immobilized analyte may then be visualized using conventional signal producing systems, such as color, fluorescence, and luminescent systems.
