Patent DE-2966602-D1 (DE)
Title: Device for moulding foamed plastic articles
Inventor: CONTASTIN ANDRE JEAN
IPC: B29B7/74
Filed: 1979-06-08
Granted: 1984-03-08
Abstract: In the course of this method, an amount of expansible mixture is poured into a mould, after which the mould is obturated by means of a plug. A vacuum is created in the chamber of the mould by way of the plug so as to cause the foaming of the mixture. The vacuum is maintained for a period after the foamable mixture has filled the whole of the volume of the mould. At the end of the polymerization of the foamable mixture, the vacuum may be re-applied in the mould, preferably for several cycles, so as to cause the cells of the foam obtained to burst.

Inventor: KNOWLES WILLIAM
IPC: G01N33/563
Filed: 1985-10-17
Granted: 1994-01-27
Abstract: Binding of a particular protein by an antibody reagent involving denaturation of the protein and use of an antibody reagent specific for binding a linear peptide epitope therein. Denaturation by chemical or physical means effectively exposes or enhances the exposure of the linear peptide epitope for binding by the antibody reagent which is preferably raised against a synthetic peptide immunogen. The technique is particularly useful in performing immunoassays for protein, in aqueous test samples. Monoclonal antibodies are also provided which are specific for the glucosylated N-terminal peptide sequence in the beta-subunit of human hemoglobin and are therefore useful in the determination of Hb Alc.

Abstract: A first glycoprotein having a molecular weight of approximately 120,000 daltons in the H9/HTLV-III cell line, of which approximately 90,000 daltons is the unglycosylated moiety, is obtained from cells infected with human T-cell leukemia virus, type III. A second glycoprotein having a molecular weight of approximately 160,000 daltons is also obtained from such cells, of which approximately 90,000 daltons is the unglycosylated moiety and is substantially identical to the unglycosylated moiety of the first glycoprotein. The presence, in a biological specimen, of either of these unglycosylated or of the unglycosylated moiety is indicative of the presence of cells infected by human T-cell leukemia virus. An assay for the glycoprotein or its unglycosylated moiety is a useful diagnostic procedure for determining such infection in biological specimens.
