Abstract: Provided are an anti-PD-L1/anti-PD-1 natural antibody structure-like heterodimeric bispecific antibody and a preparation thereof. In particular, provided are a highly stable heterodimeric anti-PD-L1/anti-PD-1 bispecific antibody with characteristics of a natural IgG and without mismatches heavy chain-light chain, and a preparation thereof. The bispecific antibody can bind to both target molecules and is more effective in treating a complex disease.

Abstract: A method for designing a high-speed multichannel optical module. Components in an optical module are classified into a circuit part and an optical path part according to functions, and the circuit part and the optical path part are separately processed and then assembled to be an optical module. Thus, modular production is implemented, and multiple parts can be processed at the same time, thereby improving the production efficiency. Moreover, if any fault occurs to either of the parts, the part can be independently replaced and maintained, thereby preventing the entire optical module from being scrapped, facilitating control of the production costs, and improving the yield rate. Also disclosed in the present invention is a high-speed multichannel optical module, which is manufactured according to the design method above. The high-speed multichannel optical module employs a modular structure, and comprises a circuit part and an optical path part which are electrically connected.

Abstract: An antibody specifically binding to PD-1 and a functional fragment thereof. The antibody or functional fragment thereof includes a PD-1 chimeric antibody and a functional fragment thereof, and a PD-1 humanized antibody and a functional fragment thereof.

Abstract: An antibody specifically binding to IL-17A or a functional fragment thereof. The antibody or functional fragment thereof includes an IL-17A chimeric antibody and a functional fragment thereof, and an IL-17A humanized antibody and a functional fragment thereof.
