| 摘要 |
An apparatus for analyzing a sample of a mixture of compounds selected from the group consisting of polynucleotides, proteins and fragments thereof attached to magnetized moieties which generate a magnetic field contained on a substrate comprising: a) a support for mounting the substrate, b) a magnetic field detector mounted adjacent the substrate, the magnetic field detector generating an electrical signal in response to a magnetic field from the substrate, c) scanning means for moving the magnetic field detector relative to the substrate, and d) an amplifier operatively connected to the magnetic field detector to amplify a signal generated thereby. |
