标题 :Method for determining a concentration of a synthesis component in a radiopharmaceutical sample
发明人：LEBEDEV ARTEM Y; ELIZAROV ARKADIJ M
权利人:TRACE ABILITY INC
摘要:A method for determining a concentration of a synthesis component in a radiopharmaceutical sample comprises providing an indicator, a metal or a metal complex, contacting the radiopharmaceutical sample with the indicator, metal or metal complex for a period of time sufficient to obtain an interaction, measuring an optical characteristic of the interacted components, and determining a concentration of the synthesis component in the radiopharmaceutical sample based on the measured optical characteristic.

标题:Activated modular grafted polymeric surfaces
发明人：EDE NICHOLAS JON; ERCOLE FRANCESCA; TRIBBICK GORDON; SANDAYAKE SAMAN; PERERA SENAKE
摘要:The present invention relates generally to new surfaces for solid phase chemistry applications, more specifically plastics surfaces modified by graft polymerisation for use in chemical synthesis and/or immobilisation of chemical entities and/or compounds. n In particular the invention relates to an activated modular grafted polymeric surface, which is suitable for use as a reagent for solid phase organic synthesis, or as a reagent for the affinity capture, presentation or preparation of biomolecules such as proteins, oligonucleotides, nucleic acids, peptides, and lectins. The grafted polymeric surfaces of the invention are particularly useful as scavenger reagents in combinatorial synthetic protocols, and as affinity reagents in protein purification and proteomics.
