    摘要: Methods are provided for producing fusion partners which involve employing an immortalized human myeloma cell line sensitive to HAT and having an additional dominant selectable resistance marker and fusing the doubly marked human myeloma cells with a stable immortalized rodent myeloma cell line, desirably previously subjected to substantial chromosome damage, and isolating cells having a substantially complete chromosomal complement of the rodent cell and at least about one chromosome of the human cell having a gene expressing said resistance, thereby being resistant to a selective agent. The resulting heteromyeloma may be fused with high efficiency with human lymphocytes to produce monoclonal antibodies.The cell lines designated as A6 and 36 were deposited at the A.T.C.C. on Jan. 11, 1983 and given accession numbers CRL8192 and CRL8193, respectively.

    摘要: A method for determining normal intrauterine pregnancy during the first 20 weeks of pregnancy comprises obtaining a test sample; and determining the presence of a fetal restricted antigen in the sample. The test sample is removed the vaginal cavity in the vicinity of the cervical canal and/or the cervical os. One fetal restricted antigen is fetal fibronectin.In one embodiment of this invention, the test sample is contacted with an insoluble support to which anti-(fetal restricted antigen) antibody is adhered, and the fetal restricted antigen binding to the support is determined. Alternatively, the test sample is contacted with an insoluble support to which is adhered an antibody which binds a class of substances including the fetal restricted antigen; and the fetal restricted antigen binding to the support is determined. Reagents and reagent kits are also included.

    摘要: Nucleated fetal cells such as nucleated fetal red blood cells are separated from maternal blood with a discontinuous triple gradient gel and centrifugation. Nucleated fetal red blood cells are collected at an interface between a gel layer having a density in the range of from 1.105 to 1.110 g/mL and the second layer having a density in the range of from 1.075 to 1.085 g/mL, and maternal granulocytes are collected at an interface between a gel layer having a density in the range of from 1.115 to 1.125 g/mL and a layer having a density in the range of from 1.105 to 1.110 g/mL. This allows separation of fetal cells for testing from the maternal blood rather than the placenta or amniotic fluid, reducing the risk of sample collection and facilitating routine testing of fetal cells for evidence of genetic defects.

    摘要: A method for determining ectopic pregnancy in pregnant persons comprises obtaining a test sample; and determining the absence of a fetal restricted antigen in the sample. The sample is obtained from the vaginal cavity in the vicinity of the cervical canal or the cervical os. One fetal restricted antigen is fetal fibronectin. In one embodiment of this invention, the sample is contacted with an insoluble support to which anti-(fetal restricted antigen) antibody is adhered, and the fetal restricted antigen binding to the support is determined. Alternatively, a class of substances of which the fetal restricted antigen is a member is captured with a general binding antibody such as an anti-(fibronectin) antibody; an anti-(fetal restricted antigen) antibody such as anti-(fetal fibronectin) antibody is bound to the support; and the absence of binding with fetal restricted antigen is determined. Competition or sandwich assay procedures can be used. Reagents and reagent kits are also included.

    摘要: Methods are provided for inducing cell death in B-cells, including neoplastic B-cells, by employing reagents that bind to a B-cell epitope. Particularly, antibodies specific for the marker can be administered to a host to induce death in B-cells to which the antibodies bind or can be used in ex vivo clinical situations to selectively remove B-cells. A B-cell specific oligosaccharide epitope useful as a B-cell marker has been identified. The ligand being recognized on B lymphocytes has no apparent similarities to any of the known pan-B cells markers. In addition, proteins which specifically bind the disclosed epitope are provided. Human monoclonal antibody 216, which recognizes this B-cell epitope, is cytotoxic to B-cells and binds all CD19.sup.+ and CD20.sup.+ B lymphocytes in human peripheral blood and spleen. Furthermore, MAb 216 does not distinguish B cells by the isotype expressed, binding IgG.sup.+ and IgM.sup.+ cells with equal intensity, and also bind all B cells regardless of their CD5 expression. Methods to inhibit neoplastic B-cell growth by administering a B-cell-cytotoxic protein are presented. These products and methods find use in diagnosis and therapy.

    摘要: A method for separating nucleated fetal red blood cells and nucleated fetal cells and maternal granular sites from maternal blood is achieved by applying maternal blood to a triple gradient gel, isolating nucleated fetal cells from the gel and binding the isolated fetal cells to a solid support by means of an anti-i antibody bound to the solid support. The separated fetal cells can then be subjected to analysis for fetal sex or genetic disorders.

    摘要: The invention provides a method for determining the presence of products of conception in a sample derived from the uterus during a D&C, or a therapeutic or spontaneous abortion, and comprises determining the presence in the sample of a fetal restricted antigen, which is found in products of conception but not found in significant amounts in maternal plasma or serum. Since the fetal restricted antigen is not present in significant quantities in maternal plasma or serum, the methods of this invention are reliable even when the sample is contaminated with maternal blood. One fetal restricted antigen is fetal fibronectin.In one embodiment of this invention, the sample is contacted with an insoluble support to which anti-(fetal restricted antigen) antibody is adhered, and the fetal restricted antigen binding to the support is determined. Alternatively, an antibody which binds a class of substances of which the fetal restricted antigen is a member can be substituted for either the capture antbody or the sandwiching antibody, and binding of fetal restricted antigen is determined. Competition assay procedures can also be used.Reagents and reagent kits are included.

    摘要: A method for determining increased risk of labor and fetal membrane rupture after week 20 of pregnancy comprises obtaining a secretion sample from the vaginal cavity; and determining the presence of a fetal restricted antigen in the sample. The sample can be removed from anywhere in the vaginal cavity, but is preferably removed from the posterior fornix or and/or cervical os. One fetal restricted antigen is fetal fibronectin. In one embodiment of this invention, the sample is contacted with an insoluble support to which anti-(fetal restricted antigen) antibody is adhered, and the fetal restricted antigen binding to the support is determined. Alternatively, the class of substances of which the fetal restricted antigen is a member is captured with a general binding antibody (such as anti-human fibronectin antibody), anti-(fetal restricted antigen) antibody (such as anti-fetal fibronectin antibody) is conjugated with the support, and binding with fetal restricted antigen is determined.Reagents and reagent kits are also included.
