  • Labeled pkg-1-alpha-binding compounds and their use in imaging and quantifying pain
    Publication number: 20160243266
    Abstract: The present invention relates to the use of compounds that selectively bind to activated protein kinase G 1 alpha for imaging the anatomic basis for chronic pain. Such imaging may also be used to objectively quantify chronic pain.

  • Method of treating colorectal carcinoma lesion and composition for use therein
    Patent number: 5643550
    Abstract: This invention provides a method of imaging a colorectal carcinoma lesion in a human patient which comprises administering to the patient a monoclonal antibody capable of binding to a cell surface antigen associated with the colorectal carcinoma lesion and which is labeled with an imaging agent under conditions so as to form a complex between the monoclonal antibody and the cell surface antigen, imaging any complex so formed, and thereby imaging the colorectal carcinoma lesion.This invention also provides a monoclonal antibody designated AS 33 (ATCC Accession No. HB 8779) and the hybridoma which produces it.
    Type: Grant
    Filed: September 27, 1994
    Date of Patent: July 1, 1997
    Assignee: Sloan-Kettering Institute for Cancer Research
    Inventors: Sydney Welt, Chaitanya R. Divgi, Samual Yeh, Lloyd J. Old, Herbert F. Oettgen, Francisco X. Real, Junichi Sakamoto
  • Hybridoma cell lines which produce monoclonal antibodies having the properties of monoclonal antibody 100-310 and the monoclonal antibodies produced by these hybridoma cell lines
    Patent number: 5565356
    Abstract: Monoclonal antibody 100-310 is found to be reactive against colon cancer cells and would therefore be useful for diagnostic imaging and treatment of colon cancer.
    Type: Grant

  • Method of imaging colorectal carcinoma lesion and composition for use therein
    Patent number: 5160723
    Abstract: This invention provides a method of imaging a colorectal carcinoma lesion in a human patient which comprises administering to the patient a monoclonal antibody capable of binding to a cell surface antigen associated with the coloretal carcinoma lesion and which is labeled with an imaging agent under conditions so as to form a complex between the monoclonal antibody and the cell surface antigen, imaging any complex so formed, and thereby imaging the colorectal carcinoma lesion.This invention also provides a monoclonal antibody designated AS 33 (ATCC Accession No. HB 8779) and the hybridoma which produces it.
