Methods for setting up, maintaining and operating a radiopharmaceutical infusion system, that includes a radioisotope generator, are facilitated by a computer of the system. The computer includes pre-programmed instructions and a computer interface, for interaction with a user of the system, for example, in order to track contained volumes of eluant and/or eluate, and/or to track time from completion of an elution performed by the system, and/or to calculate one or more system and/or injection parameters for quality control, and/or to perform purges of the system, and/or to facilitate diagnostic imaging.
摘要:
The present invention provides polypeptides, peptide dimer, and multimeric complexes comprising at least one binding moiety for KDR or VEGF/KDR complex, which have a variety of uses wherever treating, detecting, isolating or localizing angiogenesis is advantageous. Particularly disclosed are synthetic, isolated polypeptides capable of binding KDR or VEGF/KDR complex with high affinity (e.g., having a KD
摘要:
Fibrin-binding peptides having high binding affinity and excellent physical characteristics compared to previously known fibrin-binding peptides are provided. These fibrin-binding peptides may be conjugated to a detectable label or a therapeutic agent and used to detect and facilitate treatment of pathological conditions associated with the presence of fibrin such as thrombic, angiogenic and neoplastic conditions. These peptides may be used in imaging processes such as MRI, ultrasound and nuclear medicine imaging (e.g. PET, scintigraphic imaging, etc.). The peptides may also be used therapeutically. The present invention also provides processes and methods for making and using such peptides and conjugates thereof.
摘要:
The invention is directed to analogs of LHRH-II and, more generally, to analogs of the LHRH family in which modifications have been made that confer enhanced binding affinity for LHRH receptors and/or improved metabolic stability.The invention is further directed to methods of targeted therapy and targeted imaging in patients with sex-hormone-related cancers or other LHRH-mediated diseases.
摘要:
Disclosed herein is a class of linkable tetrasaccharide compounds that includes the amino phenyl glycoside of sialyl Lewis X (SLeX) and related analogs. These compounds have conjugatable nucleophilic groups, making them useful in preparing multimeric SLeX compositions. In particular, the disclosed SLeX compounds can be used to prepare selectin binding ligand conjugates by linking them to a reporter moiety, such as a contrast agent, a radiodiagnostic agent, or a cytotoxic or chemotherapeutic agent. The SLeX compounds and conjugates of the invention exhibit binding to selectin that is similar to native Sialyl Lex, and are, therefore, useful for diagnosing and treating selectin-mediated disorders and related conditions.
摘要:
New and improved compounds for use in radiodiagnostic imaging or radiotherapy having the formula M-N-O-P-G, wherein M is the metal chelator (in the form complexed with a metal radionuclide or not), N-O-P is the linker, and G is the GRP receptor targeting peptide. Methods for imaging a patient and/or providing radiotherapy to a patient using the compounds of the invention are also provided. A method for preparing a diagnostic imaging agent from the compound is further provided. A method for preparing a radiotherapeutic agent is further provided.
摘要:
The present invention provides methods and compositions that reduce target-independent primer extension or enhance template dependent primer extension. The methods and compositions of the present invention are applicable not only in PCR, but also in nucleic acid sequencing, genotyping, and other applications employing extension of a primer in a target-dependent manner.
摘要:
Multiple fluid sample processors and systems for high throughput chemical synthesis and biological assays and/or processing. A multi-layered fluidic array having microchannels, reservoirs and reaction wells is subject to robotic and automated handling. A pressure pumping system is utilized for fluid delivery and control through the synthesis process. The sizes of the micro-sized channels, apertures, and valves are adjusted to optimize fluid distribution and channel filling. The fluid sample processors can be grouped together in a microtiter format to increase the speed, quantity and efficiency of the processing.
