权利人:BIO TECHNE CORP
摘要:The ligand for VISTA is identified (VSIG3) as well as the use of this ligand and receptor interaction in the identification or synthesis of a VSIG3 agonist or antagonist compounds, preferably antibodies, polypeptides and fusion proteins which agonize or antagonize the effects of VSIG3 and/or VISTA and/or the VSIG3/VISTA interaction. These antagonists may be used to suppress VSIG3/VISTA's suppressive effects on T cell immunity, and more particularly used in the treatment of cancer, or infectious disease. These agonist compounds may be used to potentiate or enhance VSIG3/VISTA's suppressive effects on T cell immunity and thereby suppress T cell immunity, such as in the treatment of autoimmunity, allergy or inflammatory conditions. Screening assays for identifying these agonists and antagonist compounds are also provided.

权利人:UNIV GLASGOW COURT
摘要:The invention relates to a method and apparatus for performing and characterising a chemical synthesis, such as those performed with an automated chemical synthesis platform, including such that are portable platforms, the method comprising the steps of: performing a chemical synthesis in a chemical synthesiser; recording analytical data during the chemical synthesis, and developing a profile for the analytical data recorded over time; and comparing the profile for the chemical synthesis against a reference profile, which reference profile is the analytical data recorded over time for a reference chemical synthesis, wherein the chemical synthesis and the reference chemical synthesis share at least the same reagents and method steps for the same intended product, such as the chemical synthesis and the reference chemical synthesis sharing the same instruction set. The method and apparatus are for intended for use in replication of approved, chemical syntheses based on common reaction platforms.
