    摘要: The present invention provides a process for the preparation of digitalis antibodies in which appropriate mammals are immunized with a digoxin bound to protein, the animal serum is obtained, the immune globulin-containing protein fraction is separated in known manner, the immunologically-active globulins are adsorbed on an immunologically-active column and separated from the other proteins, the antibodies are again eluted from the column and the Fab fractions are split with papain and purified, wherein, as immunologically-active adsorbent, there is used an inorganic matrix of large surface area to which digitoxin aldehyde is bound via a spacer which cannot be split with papain and the splitting off of the Fab fraction from the antibodies is carried out on the matrix.The present invention also provides digitalis antibodies obtained by this process, which antibodies can be used for the therapy of digitalis intoxications and for preparing immunological reagents for the determination of digitalis glycosides.

    摘要: Nucleic acid analogues provide a particularly useful tool for the preparation of complex polymeric structures of defined geometry because they are relatively stable to reaction conditions for the preparation of such structures and provide the opportunity to introduce reactive groups which would not be possible with usual nucleic acids. These supramolecular structures can be used to form fine networks in nanometer size, for the preparation of e.g., computer chips, new materials/polymers with conductivity and/or insulator properties, and robot arms in nanometer scale.
