摘要:
Immunoassays are performed with two different ligands tagged with two different tagging constituents which are independent of each other and the two tagged ligands are immunologically bound together. The two different ligands may be detected independently through their independent tagging constituents for quality control, internal calibration (standardization), determination of viability and shelf life and the like.

Antigens specific to respiratory syncytial virus are produced on the surface of cells by:
(1) culturing in vitro cells derived from a human or animal mucosa, (2) inoculating the cultured cells with respiratory syncytial virus, and (3) selecting virally infected cells from the culture.
The resulting cells or the viral antigen(s) when partially or completely isolated from the cells have immunological and diagnostic uses in respect of infection by respiratory syncytial virus and may be used to isolate viral antibodies. A specific cell strain NM7 produced by this method from bovine nasal mucosal cells has respiratory syncytial virus antigens on its surface and its corresponding, uninfected cell strain NM5 can be infected similarly.

New compounds are prepared having the formula: wherein (1) X, is Cl, R 2 is oxygen and R 1 is -(CH 2 ) n -OH or -(CH 2 ) n -O-(CO) m (CH 2 ) P COZ or -O-(CH 2 ) P COZ or -O-(CH 2 ) p COOR 11 or is a radioisotope or (2) X 1 is Cl, R' is Hand R' is = N . O(CH 2 ) q COZ or (3) X, is a radioisotope, R 2 is oxygen and R, is OH in the 4-position and wherein n is an integer of 1-5, m is 0 or 1, p is an integer of 1-4, q is an integer of 1-3, R 11 is a C 1 -C 3 alkyl group and Z is OH or a group of formula: where s in an integer of 1-4, R 6 is a radioactive nuclide and R, is OH. Various methods for their preparation are described. The unlabelled compounds in which R, and R, contains a free carboxy group can be coupled with an immunogenic carrier to give an immunogen which can be used to raise antisera in host animals e.g. rabbits. This antisera contains antibodies specific to the antidepressant bupropion. This antisera can be used, together with the radioactive labelled compounds I in a radioimmunoassay method for determining bupropion in biological fluids as bupropion and the labelled analogue thereof compete for binding sites in the antisera. A test kit for use in the radioimmunoassay contains antisera, radioactive labelled compound I and optionally bupropion.

Es wurde gefunden, daß sich zur Bestimmung von geringen Mengen Theophyllin in biologischen Flüssigkeiten einschließlich Vollblut und haemolytischem Blut nach der Methode des Immunoassay vorteilhaft Antikörper eignen, die durch Injizieren von Antigenen, bestehend aus kovalent über die Carboxylgruppe an immunogene Träger gebundenen Theophyllin-7-alkancarbonsäuren, in Wirtstiere zu erhalten sind. Als markiertes Theophyllin eignen sich insbesondere die mit radioaktiven Jod-Isotopen iodierten Theophyllin-7-alkancarbonsäureamide mit Histamin, Tyramin und Tyrosin, sowie enzym- und fluoreszenzmarkierte Theophyllinderivate.
