  • Patent number: 11970537
    Abstract: Provided is a fusion protein dimer using an antibody Fc region as the backbone, comprising a first and a second polypeptide chain. The first polypeptide chain comprises a first antibody Fc region and one or more single-domain antibodies fused to the first antibody Fc region. The second polypeptide chain comprises a second antibody Fc region and one or more single domain antibodies fused to the second antibody Fc region. The first polypeptide chain and/or the second polypeptide chain further comprise a cytokine fused to the Fc region of the respective antibody. Further provided is use of the fusion protein dimer in preparing an immunotherapeutic drug for treating tumors. The Fc fusion protein heterodimer not only increases the activity of a single domain antibody, but also significantly improves the biological activity of a cytokine.

  • Publication number: 20210359148
    Abstract: A series-connected solar cell module is provided, which includes multiple solar cell units. each of the multiple solar cell units comprises multiple solar cells. In each of the multiple solar cell units, a back surface of one of two adjacent solar cells is electrically connected to a front surface of the other of the two adjacent solar cells through a conductive material. A first insulating layer and a second insulating layer are provided at positions where the conductive material is in close contact with the two adjacent solar cells. Therefore, adjacent solar cells can be arranged in close contact with each other, to achieve a seamless contact, thereby increasing the effective area of the series-connected solar cell module.

  • Patent number: 8069709
    Abstract: An ion-based triple sensor is disclosed. The ion-based triple sensor may include an ion sensing unit, configured to measure an ionic current intensity, a pressure sensing unit, configured to measure a pressure, and a temperature sensing unit, configured to measure a temperature. The ion-based triple sensor may further include a signal processing unit coupled to the ion sensing unit, the pressure sensing unit and the temperature sensing unit. The signal processing unit may include a filtering component, configured to filter at least one of the ion, pressure and temperature measurements, and a data acquisition component, configured to sample the filtered measurements and communicate the samples to a controller.
