  • Publication number: 20170368052
    Abstract: The present invention provides solid crystalline forms of apomorphine free base or a hydrate, solvate, or co-crystals thereof. Such crystalline forms may be advantageous over amorphous forms of apomorphine, e.g., amorphous salt forms such as acid addition salts of apomorphine, because of their increased/greater stability and/or improved pharmacological properties, e.g., decreased adverse reactions at the site of administration. The invention further provides liquid formulations obtained by dissolving said crystalline forms of apomorphine in a solvent, as well as a method for treatment of a neurological or movement disorder, e.g., Parkinson's disease, or a condition associated therewith, by administration of said liquid formulations.

  • Patent number: 5770367
    Abstract: A reagent comprises: a) an analyte moiety comprising at least two analyte residues, and linked to; b) a tag moiety comprising one or more reporter groups adapted for detection by mass spectrometry, wherein a reporter group designates analyte residue, and the reporter group at each position of the tag moiety is chosen to designate an analyte residue at a defined position of the analyte moiety. A plurality of such reagents, each comprising a different analyte moiety, provides a library of reagents which may be used in assay methods involving a target substance. Analysis of the tag moieties indicates the nature of the analyte moieties bound to the target substance. A method of sequencing nucleic acid employs a library of the reagents to determine the sequence of a target nucleic acid.
