Abstract: The present invention concerns the use of immunoassays for the characterisation, diagnosis, screening and monitoring of cancer and other diseases. In particular said immunoassays involve the use of polyclonal and monoclonal antibodies against different regions in tissue factor, particularly urinary tissue factor, and methods for generating the same. Preferably said antibodies are specific for the tissue factor signal transduction peptide region (anti-TF-STP antibodies). In particular, the present invention relates to antibodies and the use thereof which are specific for phosphorylated isoforms of TF-STP. The invention further concerns use of these anti-TF-STP antibodies to quantitate TF-STP isoforms in biological fluids, in particular urine.

Abstract: We provide a novel technological approach for quantitation of c-terminal fragment of uTF for the purpose of quantitation, diagnosis and population screening of cancer. We provide a rationale for measuring c-terminal fragment, methods for making assays, monoclonal and polyclonal antibodies, together with accepted methods of sample preparation. Taken together these proposals and ideas constitute a novel approach for diagnosis and population screening for cancers using urine from cancer patients. In addition we believe that our approach may be useful in the diagnosis of other pathological conditions.

Abstract: Branched olefins of at least 4 carbon atoms are hydroisomerized to a less branched alkane by contact with a hydrogen containing gas and a shape selective zeolite which has at least 1 metal of the Pt group supported primarily within the channels of said zeolite.

Abstract: A process for the production of aromatic compounds from low-molecular weight predominantly paraffinic feedstock which comprises contacting the feedstock in a first reactor with a dehydrogenation catalyst to produce a first reaction product containing alkenes; contacting said first reaction product in a second reactor with a crystalline aluminosilicate catalyst to produce a second reaction product containing aromatics; and separating an aromatic-rich fraction therefrom. In a preferred embodiment the feedstock consists essentially of propane and/or butane.

Abstract: A process for producing hydrocarbons comprising contacting, under conversion conditions, an aqueous methanol with a crystalline aluminosilicate zeolite catalyst which is hydrothermally stable in the temperature range of from 250.degree. C. to 500.degree. C. and is capable of converting methanol to hydrocarbons, and with a promoter comprising one or more compounds selected from the group consisting of aromatic hydrocarbons, precursors to aromatic hydrocarbons, olefins, precursors to olefins and aldehydes to form a mixture comprising light olefins, lower alkanes and monocyclic aromatic hydrocarbons and recovering said hydrocarbons.

Abstract: The invention concerns a process for the removal of catalyst residues from a gas by contacting the gas with particulate mineral oxides. The process of the invention may be applied to the removal of coordination catalyst residues from .alpha.-olefins recycled from a polymerization reactor. The process is particularly useful in the removal of alkylaluminium halides and hydrogen halides, such as diethylaluminium chloride and hydrogen chloride, from .alpha.-olefins such as propylene. The process offers the advantages of being able to be operated under anhydrous conditions, and combining high efficiency in the removal of low levels of catalyst residues with a high capacity for the catalyst residues.
