摘要:
Methods are described for the identification and preparation of high-affinity nucleic acid ligands to TGF&bgr;2. Included in the invention are specific RNA ligands to TGF&bgr;2 identified by the SELEX method. Also included are RNA ligands that inhibit the interaction of TGF&bgr;2 with its receptor.
摘要:
The object of the present invention is to provide a T cell line capable of continuously producing human immunodeficiency virus (HIV) using CC chemokine receptor 5 (CCR5); and being in a state of continuously producing human immunodeficiency virus (HIV) or in a state wherein human immunodeficiency virus (HIV) is latently infecting, and a method for isolating and producing the T cell line. The present invention related to T cell line capable continuously producing human immunodeficiency virus (HIV) using cc chemokine receptor 5 (CCR5) and being in a state of continuously producing human immunodeficiency virus (HIV) is latently infecting, a method for screenings by use of the T cell line of (1) HIV resistant to an agent having an anti-HIV activity, (2) an agent having an anti-HIV activity, (3) an agent inhibiting the transition of HIV from the latent period into the proliferation period, and (4) an agent capable of eliminating HIV from T cell line; and a pharmaceutical composition comprising the agent obtained by the above screenings of (2) to (4). A T cell line of the present invention having a continuous productivity of human immunodeficiency virus (HIV) usnig CC Chemokine receptor 5 (CCR5) is useful in screening for agents or salts thereof for the treatment or prevention of diseases such as AIDS caused by HIV.

Methods are described for the identification and preparation of nucleic acid ligands to tenascin-C. Included in the invention are specific RNA ligands to tenascin-C identified by the SELEX method. Further included in the invention are methods for detecting the presence of a disease condition in a biological tissue in which tenascin-C is expressed.
摘要:
The present invention relates to the cloning and expression of foreign protein or polypeptides in bacteria, such as Escherichia coli. In particular, this invention relates to expression tools comprising a FKBP-type peptidyl prolyl isomerase selected from the group consisting of FkpA, SlyD, and trigger factor; methods of recombinant protein expression, the recombinant polypeptides thus obtained, as well as to the use of such polypeptides.
摘要:
A test system for studying a biological fluid which comprises a tube- or pipe-like hollow body which is intended for receiving or passing through a biological fluid and on whose inside a support is attached on which binding molecules for one or more different antigens, antibodies, pathogens, toxins and/or exogenous or endogenous proteins to be detected in the biological fluid are arranged in fields separated from one another is described.
摘要:
Antigens capable of eliciting antibodies which can enhance the rate of chemical reactions at peptide bonds are disclosed. In particular, the rate of cleavage or formation of metastable peptide bonds, such as ASN-X, ASP-X, GLN-X, GLU-X, LYS-X, and HIS-Y-X, where X and Y are any amino acid, is enhanced by antibodies elicited by said antigen.
摘要:
An active peptide consisting essentially of 7 to about 30 residence and having a sequence that corresponds to a conserved domain of an HIV protein is disclosed, as is a multimer containing that peptide, an aqueous composition containing the multimer and methods of using and making the same. The aqueous composition containing an immunologically effective amount of an active peptide multimer, when introduced into an immunocompetent host animal in an immunologically effective amount, is capable of inducing cellular immunity against the native HIV protein to which the active peptide of the multimer corresponds in sequence, but is not capable of inducing production of antibodies that immunoreact with that native HIV protein.
摘要:
Retroviruses associated with Acquired Immune Deficiency Syndrome (AIDS), including Lymphadenopathy Associated Virus (LAV), are isolated from the sera of patients afflicted with Lymphadenopathy Syndrome (LAS) or AIDS. LAV is a Human Immunodeficiency Virus (HIV). Viral extract, structural proteins and other fractions of the retrovirus immunologically recongize the sera of such patients. Immunological reaction is used to detect antibodies that specifically bind to antigenic sites of the retrovirus in samples of body fluids from patients with AIDS or risk of AIDS.
摘要:
This invention comprises nucleic acid ligand for use as a diagnostic reagent for detecting the presence or absence of a target molecule in a sample, and a diagnostic reagent to measure the amount of a target molecule in a sample. In a preferred embodiment the nucleic acid ligands are identified by the method of the invention referred to as the Systematic Evolution of Ligands by EXponential enrichment (SELEX), wherein a candidate mixture of nucleic acids are iteratively enriched in high affinity nucleic acids and amplified by further partitioning.
摘要:
The present invention discloses a novel method for the rapid screening of candidate cytotoxic T lymphocyte- (CTL-) inducing compounds, such as peptides, by the in vivo priming of CTLs with synthetic peptides. The use of compounds so identified for the development of CTL vaccines for the treatment of various infectious disorders, including the treatment of viral diseases such as AIDS, herpes, influenza, and feline or bovine leukemia, is also disclosed, as is the use of this methodology for the preparation of specifically primed CTLs.
