Latest Patents

Orchansky holds a patent for the "Human gamma interferon-specific receptor protein, antibody against said." This patent details the analysis of [.sup.125 I] interferon gamma cross-linked to its receptor on various human cells. The research revealed at least three different types of human interferon gamma receptors. In WISH, HeLa, FS11, and other tissue cells, a receptor with a molecular weight of 90,000-105,000 was identified. In monocytes and the myeloid cell line KG-1, a receptor with a molecular weight of 140,000 was found, while in Daudi lymphoblastoid cells, a receptor with a molecular weight of 95,000-115,000 was observed. The various receptors were isolated from these cells through extraction followed by affinity chromatography on an immobilized interferon gamma column. The resulting purified preparations retained their original affinity for interferon gamma and were utilized for immunizing mice, leading to the development of highly specific antibodies.
