  • Patent number: 9057727
    Abstract: The present invention provides screening methods for GPCRs based on the discovery that the affinity of a receptor agonist for a GPCR (such as the parathyroid hormone receptor) when not bound to a G-protein is correlated with the length of time over which the agonist is effective, independently of its pharmacokinetic properties. The invention also provides PTH- and PTHrP-derived polypeptides.

  • Patent number: 6068840
    Abstract: Monoclonal antibodies immunospecific for the neutrophil chemotactic factor, IL-8, have been humanized by reshaping the variable regions to conform more closely to human counterparts. These antibodies are useful in immunoassays to detect IL-8 and as ligands on immunoaffinity columns for purification of human IL-8. In addition, the humanized antibodies have an antiinflammatory effect in patients.

  • Patent number: 5968784
    Abstract: The present invention provides novel methods for identifying gene expression patterns in mRNA populations. The methods are useful for determining differential gene expression among various cells or tissues, including cells or tissues of a target organism. The invention also provides methods of determining the frequency of gene expression in mRNA populations, thus providing a method of comparing gene expression frequency among various cells or tissues. The present invention also provides methods for isolating genes corresponding to tag sequences identified according to the methods of the present invention. Furthermore, sequences that are identified according to the present invention may be used to diagnose the presence of disease.

  • Patent number: 5866341
    Abstract: A method of screening for binding partners of a specific molecule. The method employs a chimeric protein having at least two different binding regions; one containing at least a portion of the specific molecule or an analog thereof, and the other containing a binding region of an immunoglobulin chain. In a preferred embodiment, the method is used for rapidly screening member compounds of a combinatorial library for potential biological activity.

  • Patent number: 5464828
    Abstract: The invention is an aqueous suspension of sucralfate (sucrose sulfate aluminum salt), which is added with a starch and/or a derivative thereof and preferably further with a cellulose derivative, polysaccharide gum, alginic acid, alginate and/or bentonite, whereby the suspension is made stable for a long time and may be redispersed if necessary. The invention can thus provide a liquid pharmaceutical preparation useful for protecting ulcer areas on mucous membranes of the stomach and duodenum industrially for the first time, although solid pharmaceutical preparations have been available.
