Title: Bispecific and oligospecific mono-and oligovalent receptors, production and applications thereof
Inventor: BOSSLET KLAUS
IPC: C12N5/10
Filed: 1990-06-22
Granted: 1999-04-01
Abstract: The invention relates to bispecific and oligospecific, mono- and oligovalent receptors which are prepared by genetic manipulation by fusion of DNA coding for F(ab) fragments of the antibodies of two or more different specificities, using suitable linkers. Preferably one of these specificities is directed against an epitope, which is located either on the cell membrane or in the interstitium, of a tumour-associated antigen (TAA) while the other specificities relate to high molecular or low molecular weight ligands and react, for example, with the complexons ethylenediaminetetraacetate or diethylenetriaminepentaacetate in Y90-complexed form (EDTA-Y90 or DTPA-Y90). In a particularly preferred embodiment, the binding to the complexons takes place on the complexon-receptor arm via fos-jun interaction (or else avidin-biotin interaction). Further preferred specificities have catalytic properties.

Title: Process for preparing reactive polystyrene group resins
Inventor: HO SUNG-MU
IPC: C08F212/08
Filed: 1990-07-31
Granted: 1993-04-19
Abstract: The  reactive  polystyrene  based  resin  is  prepared   by: preparing the prepolymer by the bulk polymerisation of  the  mixt. comprising 90.0-99.5  wt.pts.  of  styrene  monomer  and  0.5-10.0 wt.pts. of 2-vinyl-2-oxazoline or 2-vinyl-isoprophenyl-2-oxazoline monomer  to  30-40  %  of  polymerising  ratio   by   adding,   as polymerization controlling agent, 0.01-0.3 wt.%  of  one  cpd.  of tertiary dodecyl mercaptan,  lauryl  mercaptan,  nonyl  mercaptan, carbon tetrachloride, organic disulfide or cumen, w.r.t. the total resin component; then adding a suspension solution and suspending, and adding a polymerization initiator and suspension-polymerising.
