Abstract: The present invention provides a rabies virus monoclonal antibody 2F2 and universal rabies virus antibody rapid detection test paper and belongs to the technical field of biological detection. An amino acid sequence of the monoclonal antibody 2F2 is shown as SEQ ID No. 1. The monoclonal antibody 2F2 provided by the present invention specifically binds to rabies virus G proteins, and preparation of the monoclonal antibody 2F2 into test paper has the advantages of rapidity, accuracy, sensitivity, specificity and low cost.

Abstract: A 3D printing technology-based processing apparatus and method includes a frame, an injection unit, and a molding unit. A melted polymer filler can be filled into a blind hole or a passageway of a 3D printed product to improve overall strength of the product. A 3D printed product having a mortise and tenon shaped mechanical engagement structure is disclosed. The printed product having the mortise and tenon shaped structure has higher tensile strength and shear strength. The present apparatus effectively resolves a problem of warped and deformed products due to an excessive temperature difference between the product and an environment during printing. The method uses an optimized printing process to reduce the fabrication processes of a support structure, reduce consumables required for building the structure, and improve the printed surface quality of the printed product.
