  • Process for the scaleable purification of plasmid DNA
    Patent number: 6797476
    Abstract: The present invention relates to a nonchromatographic-based process for the isolation of clinical grade plasmid DNA from bacterial cells. The exemplified methods described herein outline a scaleable, economically favorable protocol for the purification of clinical grade plasmid DNA from E. coli which includes CTAB-based precipitation of DNA in combination with adsorption of impurities to calcium silicate.
    Type: Grant

  • Method of determining parameters of an n-gate
    Publication number: 20020191711
    Abstract: The invention relates to a method for determining the parameters, in particular the characteristics of an n-gate, in particular in an amplifier (8). The parameters are determined by applying and optional simultaneous measurement of an input signal sequence with various amplitudes and measuring an output signal sequence, taking into account a skew which the output signal sequence has relative to the input signal sequence. The skew is thus determined by correlation of output signal sequence with the input signal sequence.
