Abstract: The present invention relates to pharmaceutical compositions capable of specifically inducing cell death in the proliferating angiogenic endothelial cells associated with solid tumors and other angiogenesis associated diseases. More specifically, the present invention relates to nucleotide constructs that are selectively active in angiogenic endothelial cells and that encode highly toxic agents, such as diphtheria toxin, for expression in such cells.

Abstract: Methods and associated compositions are described for enhancing the selective delivery of therapeutic, diagnostic and imaging agents to activated vascular sites.

Abstract: The present invention provides a process for the determination of a protein according to the fluorescence polarization immunoassay principle in a homogeneous system by simultaneous incubation of the sample solution witha) a peptide sequence, labelled with a fluorescing compound, of 6 to 14 amino acids, two of which are cysteine which form a disulphide bridge with one another, the sequence thereby corresponding to an epitope sequence of the protein to be determined, andb) an antibody which is specifically bindable not only with the protein but also with the peptide sequence and displays for the fluorescing peptide sequence of the protein and the native protein molar relative affinities which differ by a factor of at most 6, and measurement of the depolarization of polarized light passed through the incubated solution.

Abstract: In body fluids containing saliva alpha amylase and pancreatic alpha amylase, pancreatic alpha amylase is determined with a monoclonal antibody which specifically binds but does not inhibit saliva alpha amylase and which has a cross-reactivity of 5% or less toward pancreatic alpha amylase. The monoclonal antibody binds salvia alpha amylase to form a complex which is separated to permit determining pancreatic alpha amylase with an amylase detection system. The complex may be separated by precipitating with a precipitating agent such as an anti-antibody or protein A, or by immobilizing the monoclonal antibody on a solid carrier.

Abstract: The present invention provides a monoclonal anti-alpha-amylase antibody which non-specifically inhibits the enzyme activity of human alpha-amylase by more than 90%.The present invention also provides a process for obtaining this monoclonal antibody and a medicament containing it.
