Patents by Inventor Robert Allan Zivin

Robert Allan Zivin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7041459
    Abstract: Methods, compositions and kits are disclosed for determining one or more target polypeptides in a sample where the target polypeptides have undergone phosphorylation. A mixture comprising the sample and a first reagent comprising a cleavage-inducing moiety and an IMAC resin for a binding site on a target polypeptide is subjected to conditions under which binding of respective binding moieties occurs. The binding site is the result of phosphorylation activity involving the target polypeptide. The method may be employed to determine the target polypeptide itself. In another embodiment the presence and/or amount of the target polypeptide is related to the presence and/or amount and/or activity of an agent such as an enzyme involved in phosphorylation of the target polypeptide.

  • Publication number: 20040115614
    Abstract: The present invention provides a system that is capable of supplying electric field stimulation to a cell and optically monitoring a physiological response of the stimulated cell. The invention also provides methods of eliciting a physiological response in a cell or characterizing the biological activity of a candidate compound using an electrical field stimulation (EFS) device. Such methods are readily amenable to high throughput screen (HTS).

  • Patent number: 6750325
    Abstract: The invention provides recombinant antibody molecules comprising antigen binding regions derived from the heavy and/or light chain variable regions of a donor anti-CD3 antibody, e.g. OKT3, and which have anti-CD3 binding specificity, preferably of affinity similar to that of OKT3. The recombinant antibody is preferably a humanized antibody and may be a chimeric or CDR-grafted antibody. A method is disclosed for preparing CDR-grafted humanized antibodies in which, in addition to the CDR's non-human antibody residues are preferably used at positions 23, 24, 49, 71, 73 and 78 of the heavy chain variable region and at positions 46, 48, 58, and 71 of the light chain variable region. The recombinant, especially the humanized, anti-CD3 antibodies may be used for in vivo therapy or diagnosis.

  • Publication number: 20040006094
    Abstract: This invention provides novel neuroprotective 4-pyrimidineamine derivatives and neuroprotective pharmaceutical compositions comprising 4-pyrimidinamines. This invention also provides methods of using these compositions to prevent ischemic cell death, particularly neuronal cell death, and reduce the likelihood of neuronal cell death in a subject due to a traumatic event. Finally, this invention provides an apparatus for administering to a subject the instant pharmaceutical compositions.
