Abstract:
There is provided a positron-emitting 18F-labelled Factor VIIfor non-invasive PET imaging of tumor TF expression in humans. More specifically the invention relates to human TFPET imaging of pancreaticcancer metastasis for diagnosis, staging, treatment monitoring and especially as an imaging biomarker for predicting prognosis, progression and recurrence.
Abstract:
The present invention provides antibodies and antigen-binding molecules thereof which specifically bind the α and/or &bgr; subunits of the non-active form of the GPIIb/IIIIa receptor. The antibodies and antigen-binding molecules can be genetically fused and/or conjugated to heterologous moieties and used, for example, as targeting moieties. The invention also includes methods for screening for these antibodies, as well as methods of making and methods of using chimeric molecules derived from the antibodies.
Abstract:
The present invention relates to methods for mitigating a reaction inhibition in endotoxin assay in the presence of a salt ion, methods for producing a water soluble horseshoe crab Factor C for use in endotoxin assay in the presence of a salt ion, and methods for measuring endotoxin in a test specimen.
Abstract:
Methods for identifying modified proteases with modified substrate specificity or other properties are provided. The methods screen candidate and modified proteases by contacting them with a substrate, such as a seipin, an alpha macroglobulins or a p35 family protein or modified serpins and modified p35 family members or modified alpha macroglobulins, that, upon cleavage of the substrate, traps the protease by forming a stable complex. Also provided are modified proteases.
Abstract:
The present invention provides a new method for engineering or evolving enzymes to have desirable characteristics. Among the desirable characteristics is the ability to control catalytic activity through the use of a trigger molecule that rescues a catalytic site defect introduced during the engineering process. The method includes co-evolving enzyme and substrate to retain or improve substrate binding activity in the absence of catalytic activity.
Abstract:
Methods for identifying modified proteases with modified substrate specificity or other properties are provided. The methods screen candidate and modified proteases by contacting them with a substrate, such as a serpin, an alpha macro globulins or a p35 5 family protein or modified serpins and modified p35 family members or modified alpha macroglobulins, that, upon cleavage of the substrate, traps the protease by forming a stable complex. Also provided are modified proteases
Abstract:
The present invention generally relates to edible compositions and methods to produce them. In particular, the present invention relates to the enzymatic modulation of macron utrients and to food compositions containing such modulated macronutrients. One embodiment of the present invention is a method for modulating macronutrients comprising the steps of producing at least one synthetic gene coding for at least one enzyme or a functional part thereof capable of modulating macronutrients, expressing the at least one enzyme or a functional part thereof, and bringing the macronutrients into contact with the at least one enzyme or a functional part thereof exhibiting the enzymatic activity.
Abstract:
We have identified by molecular cloning a protease which originates from the larvae of Lucilia sericata and which was termed debrilase due to its activities useful for debridement of wounds. Described is a nucleic acid molecule encoding a serine protease having the ability to cleave fibrin and casein which is (a) a nucleic acid molecule encoding the serine protease comprising or having the amino acid sequence of SEQ ID NO: 2; (b) a nucleic acid molecule comprising or having the nucleotide sequence of SEQ ID NO: 1; (c) a nucleic acid molecule encoding a serine protease the amino acid sequence of which is at least 80 % identical to the amino acid sequence of (a), preferably at least 85 % identical, more preferably at least 90 % identical, and most preferred 95% identical; (d) a nucleic acid molecule comprising or having a nucleotide sequence which is at least 80 % identical to the nucleotide sequence of (b), preferably at least 85 % identical, more preferably at least 90 % identical, and most preferred 95% identical; (e) a nucleic acid molecule which is degenerate with respect to the nucleic acid molecule of (b) or (d); or (f) a nucleic acid molecule corresponding to the nucleic acid molecule of any one of (a) to (d) wherein T is replaced by U.
