摘要:
The present invention provides molecular switch system methods and compositions for use in regulatable gene expression. The system includes a nucleic acid construct which has a DNA response sequence for a transcriptional regulatory protein operably linked to a promoter, a compound binding sequence in the vicinity of the DNA response sequence, a transgene under the control of the promoter; and a DNA binding compound. In some cases, the molecular switch system further includes a nucleic acid sequence encoding a transcriptional regulatory protein operably linked to a second promoter. The invention further provides a method for screening compounds for the ability to function in the molecular switch system and thereby regulate gene expression.
摘要:
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.

The present invention defines a DNA: protein-binding assay useful for screening libraries of synthetic or biological compounds for their ability to bind DNA test sequences. The assay is versatile in that any number of test sequences can be tested by placing the test sequence adjacent to a defined protein binding screening sequence. Binding of molecules to these test sequence changes the binding characteristics of the protein molecule to its cognate binding sequence. When such a molecule binds the test sequence the equilibrium of the DNA:protein complexes is disturbed, generating changes in the concentration of free DNA probe. Numerous exemplary target test sequences (SEQ ID NO:1 to SEQ ID NO:600) are set forth. The assay of the present invention is also useful to characterize the preferred binding sequences of any selected DNA-binding molecule.

摘要:
Polypeptide antigens are disclosed which are immunoreactive with sera from individuals having a non-A, non-B, non-C, non-D, non-E Hepatitis, herein designated Hepatitis G Virus (HGV). Corresponding genomic-fragment clones containing polynucleotides encoding the open reading frame sequences for the antigenic polypeptides are taught. The antigens are useful in diagnostic methods for detecting the presence of HGV in test subjects. The antigens are also useful in vaccine and antibody preparations. In addition, the entire coding sequences of two HGV isolates are disclosed. Methods are presented for nucleic acid-based detection of HGV in samples and also methods for the isolation of further genomic sequences corresponding to HGV.
摘要:
The present invention defines an assay useful for screening libraries of synthetic or biological compounds for their ability to bind specific DNA test sequences. The assay is also useful for determining the sequence specificity and relative DNA-binding affinity of DNA-binding molecules for any particular DNA sequence. Also described herein are potential applications of the assay, including: 1) the detection of lead compounds or new drugs via the mass screening of libraries of synthetic or biological compounds (i.e., fermentation broths); 2) the design of sequence-specific DNA-binding drugs comprised of homo- or hetero-meric subunits of molecules for which the sequence specificity was determined using the assay; and 3) the use of molecules for which sequence specificity was determined using the assay as covalently attached moieties to aid in the binding of nucleic acid or other macromolecular polymers to nucleic acid sequences.
