Abstract: The present invention relates to a “one-pot process” for preparing intermediate of antibody-drug conjugate. The preparation process provided by the present invention is simple in operation, and needs no such steps like concentration, washing and filtration of the intermediate reaction liquid, disposal of the organic waste liquid, and packaging and storage of the intermediate. The entire reaction system comprises only one separation and purification treatment, saving costs for labor, equipment, venues, raw materials, etc., and greatly reducing the pollution to the environment. In addition, the “one-pot process” for preparing intermediate of antibody-drug conjugate of the present invention produces the intermediate of antibody-drug conjugate with higher yield. The “one-pot process” for preparing intermediate of antibody-drug conjugate provided by the present invention is more suitable for scale-up production.

Abstract: Provided are a support plate, a display apparatus and an electronic device. The support plate includes flat regions including first and second flat regions spaced apart along a first direction, a bendable region between the first and second flat regions, and a pattern region covering at least the bendable region. A plurality of hole groups arranged along the first direction are disposed in the pattern region, and each hole group includes a plurality of holes at intervals along a second direction. At least two of holes in part of the pattern region covering the bendable region are oblique holes, and central axes of the oblique holes intersect with a thickness direction of the bendable region at a non-zero included angle. The central axes of the oblique holes are located in a first datum plane, and the bendable region bends along the thickness direction perpendicular to the first and second directions.
