  • Patent number: 6379891
    Abstract: Viral proteins derived from an enterically transmitted non-A/non-B viral hepatitis agent (HEV) are disclosed. In one embodiment, the protein is immunologically reactive with antibodies present in individuals infected with the viral hepatitis agent. This protein is useful in a diagnostic method for detecting infection by the enterically transmitted agent. Specific epitopes have been identified that are reactive with sera of individual infected with different strains of HEV. Also disclosed are DNA probes derived from a cloned sequence of the viral agent. These probes are useful for identifying and sequencing the entire viral agent and for assaying the presence of the viral agent in an infected sample, by using probe-specific amplification of virus-derived DNA fragments.

  • Patent number: 6361938
    Abstract: A method of identifying a peptide which permits or facilitates the transport of an active agent through a human or animal tissue. A predetermined amount of phage from a random phage library or a preselected phage library is administered in vivo or in situ to a site in an animal, such as into the gastro-intestinal tract. At a predetermined time, the phage which is transported across a tissue barrier is harvested at a harvesting site, such as in portal or systemic blood or brain tissue, which is separated from the site of administration by the tissue barrier to select transported phage. This transported phage is amplified in a host. This cycle of events is repeated (using the transported phage produced in the most recent cycle) a predetermined number of times to obtain a selected phage library containing phage which can be transported from the site of administration to the harvesting site.

  • Patent number: 6355427
    Abstract: The lifetime probability of a woman developing breast cancer can now be determined based on an allelic variation found in the 3′UTR of the prohibitin gene. The probability is dependent on the sequence of the 3′UTR at position 729, i.e., whether there is a thymine (T) or a cytosine (C) or both at this position. Polymorphism at position 729 is also disclosed as a susceptibility indicator for hereditary breast cancer in men. Determining the sequence at the position 729 can be done by any number of standard techniques. Preferably, the sequence is determined by amplifying this region by PCR and subjecting it to an RFLP analysis.
