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 method and kit for determining antibody sensitivity and quality of a clone cell stain. The method comprises: obtaining a solid-phase carrier, cells and an antibody; adsorbing the antibody on the solid-phase carrier; incubating the cells and the antibody; preserving cells bound with the antibody; and dyeing and counting the cells bound with the antibody, so as to determine the antibody sensitivity or the quality of the clone cell stain based on the cell count. The kit comprises components used in the method.

Abstract: A reagent for classifying and counting leukocytes containing (1) a cyanine fluorescent dye; and (2) a glycoside compound; a reagent kit containing the reagent for classifying and counting leukocytes as well as its preparation process; and a process for classifying and counting blood cells using the reagent or kit are provided. Using the reagent, kit and/or process provided, leukocytes can be classified and counted in four groups with a high degree of differentiation and a better classification among each subpopulation of leukocytes, especially in that it successfully addresses the indistinct classification between lymphocytes and monocytes and between the eosinophils and neutrophils in a scattergram.

Abstract: A compound having the general formula I or a conjugate thereof, wherein various groups are as defined in the specification. A composition includes: (i) a compound having the general formula I or a conjugate thereof; and (ii) at least one surfactant selected from cationic surfactants and nonionic surfactants. Also disclosed is a preparation method for the composition and a kit comprising the composition. Further disclosed is a method for identifying and differentiating erythroblasts, basophils and lymphocytes simultaneously using the composition according to the present disclosure.
