Abstract:
This invention relates to a composition of a non-labeled monoclonal antibody binding to a tumor antigen and a second monoclonal antibody labeled with a NIR fluorescence label, binding to the same tumor antigen, wherein the first and second antibody exhibit no cross reactivity. The composition can be used for the treatment of patients suffering of solid tumors which are associated with an overexpression of such a tumor antigen. The invention further relates to a the co-administration of said first and second antibody as wells as to a method of acquiring a NIR fluorescence images of such tumors or the patients suffering from such tumors during the treatment of said patientwith such composition.
Abstract:
The present invention relates to the field of therapeutic antibodies. It especially relates to the study of therapeutic antibodies in an experimental animal. The present invention discloses a method of detecting a therapeutic antibody in a sample obtained from an experimental animal comprising the steps of a) providing the sample to be analyzed, b) incubating said sample with an antibody binding to a therapeutic antibody and not binding to the immunoglobulin of said experimental animal, c) optionally incubating said sample with a reagent appropriate for the selective detection of total, active or antigen-bound therapeutic antibody, and d) correlating the complex formed in (b) or (c) to the concentration of said therapeutic antibody. A monoclonal antibody directed to a certain epitope that is present on all classes of human immunoglobulin of class G, but not on the immunoglobulin of any experimental animal except on the IgG of chimpanzees was used (MAB-M-R10Z8E9) .
Abstract:
A compound has general formula (I), in which Bi is a residue obtained by splitting a carboxyl group from biotin or a biotin derivate; R and R represent independently from each other hydrogen or C1-C4-alkyl; n is an integer from 4 to 10; and X is an alkylene residue substituted by one or several O and/or S atoms, having a 5 to 20 atom long chain. Also disclosed is a conjugate of this compound with a substance having at least one primary and/or secondary amino group NHR .
Abstract:
The present invention relates to the field of therapeutic antibodies. The invention especially relates to a method of detecting the target antigen of a therapeutic antibody in a sample comprising the steps of a) providing the sample to be analyzed, b) incubating said sample with said therapeutic antibody under conditions appropriate for binding of said therapeutic antibody to said target antigen, whereby a target antigen-therapeutic antibody-complex is formed, and c) detecting the complex formed in (b).

Abstract:
This invention relates to a composition of labeled and non-labeled monoclonal antibodies directed to a human transmembrane protein for the simultaneous treatment and diagnosis of diseases which are associated with an overexpression of such a protein especially of cancer. The invention further relates to a method of first administering said composition, determine the change of labeled antibody concentration and afterwards administering the non-labeled monoclonal antibodies only such that the minimum required concentration of such non-labeled antibody for a favorable therapeutical effect is achieved and maintained in the treatment, while unfavorable side effects are minimized due to the lower systemic antibody concentration.
Abstract:
Bei einem Verfahren zum Steuern eines elektrischen Verstärkers (EV), bei dem ein eine Endstufe (ES) des Verstärkers (EV) ansteuerndes Reglersignal (RS) überwacht wird, wird das Reglersignal (RS) in Abhängigkeit eines Ausgangsignals (U out) der Endstufe (ES) eingestellt. Dabei wird das Reglersignal (RS) mit einem Referenzsignal (REFS) verglichen, wobei beim Durchschreiten eines Amplitudengrenzwertes (REF O, REF U) und eines Periodendauergrenzwertes (PGW) des Referenzsignals (REFS) vom jeweiligen Amplitudenwert (AW) bzw. Periodendauerwert (PW) des Reglersignals (RS) die Endstufe (ES) eingangsseitig sperrend angesteuert wird.
Abstract:
Die Erfindung betrifft einen elektrischen Verstärker mit einer Endstufe (6), die durch eine elektrische Energiequelle versorgbar ist, wobei die Endstufe (6) eingangsseitig mit einer Steuerungseinrichtung (4) verbunden ist, durch deren Steuersignal ein von einem Parameterwert der Energiequelle abhängiges Ausgangssignal der Endstufe (6) steuerbar ist. Gemäß der Erfindung ist eine Kompensationseinrichtung (9) vorgesehen, die mit der Energiequelle und der Steuerungseinrichtung (4) verbunden ist, und durch die das Steuersignal in Abhängigkeit von dem Parameterwert der Energiequelle veränderbar ist. Der Parameter kann z.B. die Netzspannung der Energiequelle sein. Die Erfindung betrifft weiter ein Verfahren zum Steuern eines elektrischen Verstärkers mit einer Endstufe (6), die durch eine elektrische Energiequelle versorgt wird, wobei ein Parameterwert der Energiequelle ermittelt, daraus ein Kompensationssignal abgeleitet und in Abhängigkeit davon ein Steuersignal für die Endstufe (6) gebildet wird. Der elektrische Verstärker und entsprechend das Verfahren können vorteilhaft als Gradientenverstärker für ein Magnetresonanzgerät eingesetzt werden.
Abstract:
The invention relates to a method for purifying a target substance from a biological sample, involving immobilisation of the target substance on a solid phase through a high affinity binding pair, and follow-on elution through addition of a partner of the binding pair in a free form. The invention further relates to reagent kits for carrying out the inventive method.
