  • Amplifier systems
    Patent number: 11949382
    Abstract: The present disclosure relates to circuitry comprising: amplifier circuitry configured to receive a variable supply voltage, wherein the supply voltage varies according to an output signal of the amplifier circuitry; monitoring circuitry configured to monitor one or more parameters of an output signal of the amplifier circuitry; and processing circuitry configured to receive an indication of the voltage of the variable supply voltage and an indication of the monitored parameters from the monitoring circuitry and to apply a correction to one or more of the monitored parameters to compensate for coupling between the variable supply voltage and the monitoring circuitry.

  • METHODS OF PURIFYING POLYPEPTIDES
    Publication number: 20190330267
    Abstract: The present invention relates to improved processes for purifying polypeptides of interest by increasing the amount of a polypeptide of interest bound to an ion-exchange matrix relative to the amount of one or more impurities bound to the ion-exchange matrix. This effect is achieved by adding a chemical compound in the process which by also binding to the ion-exchange matrix due to a change that is opposite to the change of the ion-exchange matrix, reduces the binding of impurities more than the binding of the polypeptide of interest.

    Publication number: 20160185816
    Abstract: The present invention relates to improved processes for purifying polypeptides of interest by increasing the amount of a polypeptide of interest bound to an ion-exchange matrix relative to the amount of one or more impurities bound to the ion-exchange matrix. This effect is achieved by adding a chemical compound in the process which by also binding to the ion-exchange matrix due to a charge that is opposite to the charge of the ion-exchange matrix, reduces the binding of impurities more than the binding of the polypeptide of interest.
