Abstract: The present application provides an anti-reflectance film and a display device. The display device includes a display panel and the anti-reflectance film located on a light-emitting side of the display panel. The anti-reflectance film includes a substrate, a transition layer, and an anti-reflectance layer. The transition layer is located on a side of the substrate. The anti-reflectance layer is located on a side of the transition layer away from the substrate. A refractive index of the transition layer is greater than a refractive index of the substrate.

Abstract: Provided are a molecule specifically binding to CLDN18.2, the molecule comprising an immunoglobulin single variable domain, a nucleic acid molecule encoding the molecule specifically binding to CLDN18.2, and an expression vector and a host cell for expressing the molecule specifically binding to CLDN18.2; further provided are a method for producing the molecule specifically binding to CLDN18.2 and use thereof for treating or preventing conditions associated with CLDN18.2.

Abstract: The present application provides an isolated PD-L1 binding molecule, specifically, an isolated PD-L1 single-domain antibody or an antigen-binding fragment thereof. The present invention also provides a nucleic acid encoding the isolated PD-L1 binding molecule, an expression vector or host cell comprising the nucleic acid, and a pharmaceutical composition or kit comprising the PD-L1 binding molecule.
