摘要:
This invention is directed to reprogramming an adult cell nucleus to produce an embryo. The process involves: taking a donor cell or nucleus; fusing the donor nucleus with a recipient cell that has not been enucleated to procude an aneuploid cell; waiting a period of time to allow the donor nucleus to be reprogrammed; and removing the recipient cell nucleus. This process results in an embryo with a reprogrammed nucleus.

The present invention provides a truncated Reelin protein containing a F-spondin domain and a CR-50 recognition site but containing no repeat site of a Reelin protein, and a DNA encoding the truncated Reelin protein. The truncated Reelin protein and the DNA encoding this protein of the present invention can be utilized for treatment of diseases including agyria due to abnormal alignment of neurons.

Antibodies to intracellular domains of two or more kinds of protein tyrosine phosphatases, methods for generation thereof and cells producing these antibodies are disclosed. The antibody of the present invention may have specificity to intracellular domains of phosphatase subunits of both of LAR and CD45, and may be useful for analysis and quantitative determination of PTPs, identification and detection of novel PTPs, and for obtaining novel phosphatases by cloning and the like, as well as for developing useful diagnostic methods of insulin resistance and NIDDM, for prophylaxis and diagnosis of various disease states of syndrome X that is based on insulin resistance, and for prophylaxis and diagnosis of onsets of arteriosclerosis and cardiac diseases.
摘要:
In a screening method for identifying a substance for the treatment of bone disorders that are associated with reduced bone mass, the substance is tested for its ability to upregulate the expression of Fra-1 or to modulate the expression of a Fra-1 target gene in osteoblasts, said upregulation or modulation resulting in an increased bone formation in vivo. The identified osteoinductive compounds and DNA molecules encoding biologically active Fra-1 molecules can be used for the therapy of bone disorders characterized by a circumscribed or systemic reduction of bone mass.

The present invention relates to FMRF amide type peptides and their non-amidated precursors, to recombinant nucleic acids encoding for such peptides, to the use of these nucleic acids, in forms substantially isolated from other nucleic acid or when incorporated into vectors, to transform organisms in order to render them capable of producing these peptides, to the use of such peptides, nucleic acid and vectors as pesticidal agents, eg. insecticidal, acaricidal and helminthecidal agents and to compositions comprising one or more of these. A peptide or salt thereof comprising an amino acid sequence Pro-Pro-(Xaa1)n-Phe-Xaa2-Arg-Xaa3 or a conservatively substituted analogue thereof, wherein the N terminal of said peptide may be free amino or protected amino and the C-terminal of said peptide, which is the C-terminal -Xaa3 of the above sequence, may consist of that residue with a free carboxylic acid group or with an amidated carboxyl of the formula CONR1R2 wherein R?1 and R2¿ are independently selected form hydrogen, alkyl, alkenyl, hydroxyalkyl, alkoxyalkyl and aminoalkyl or together with the nitrogen to which they are attached form a C¿3-8? heterocyclic ring; wherein Xaa?1¿ is any amino acid, which is independently selected at each repeat n, and n is an integer from 0 to 10 and Xaa2 is Met, Val, Ile, Leu, Nle or Phe or a conservatively substituted analogue thereof and Xaa3 is Phe, Asp or Glu, provided that when the peptide is Ile-Pro-Pro-Gln-Phe-Met-Arg-Phe it is not combined with skin of the frog Hylambates (Kassina maculata) is specifically claimed as are nucleic acids encoding therefor.
摘要:
An antiannexin-V monoclonal antibody is produced from a hybridoma cell line that is prepared by using a human annexin V alone or together with a canine annexin V, has a binding specificity for the antigenic determinant site of annexin V, an antigenic protein, and produces an antiannexin-V monoclonal antibody belonging to immunoglobulin G. The antiannexin-V monoclonal antibody thus produced is used to diagnose myocardial infarct and angina pectoris, and the first and second antiannexin-V monoclonal antibodies produced from the respective hybridoma cell lines are used to diagnose myocardial infarct and/or angina pectoris by quantifying the human annexin V contained in specimens. The quantifying method comprises effecting an antigen-antibody reaction between the human annexin V and the first antiannexin-V monoclonal antibody to form a human annexin V antigen-antiannexin-V monoclonal antibody complex, binding a labeled antiannexin-V polyclonal antibody or the second monoclonal antibody to the annexin V antigen moiety of the formed antigen-antibody complex to form a labeled conjugate between the antigen-antibody complex and the polyclonal or second monoclonal antibody, and quantifying the labeled conjugate thus formed.
摘要:
A monoclonal antibody (FE8) against human complement receptor type 2 (CR2, CD21) which is able to substantially remove C3-derived fragments already attached to CR2, in particular C3dg from CR2 at temperatures of 25°C and above. Furthermore, the invention covers hybridoma cells and processes to obtain antibodies, as well as therapeutic applications.
摘要:
A monoclonal antibody that recognizes each of the epitopes present at the 10th to 220th, 221st to 297th and 469th to 662nd positions from the N-terminal amino acid of human Mx protein MxA and reacts specifically with the Mx protein by western blotting, immunoprecipitation or immunocyte staining; and a hydbridoma that produces the antibody. This antibody is useful for diagnosing viral infection.
