The invention provides a treatment method and a treatment agent for a biological specimen. According to the treatment method provided by the invention, before a biological specimen is in contact witha cross-linking agent, the surface of the biological specimen is coated with gelatin to form a gelatin coating layer. The treatment method comprises the following main steps: 1, wrapping a biologicalspecimen with heated gelatin hydrogel; and 2, cooling and solidifying the gelatin hydrogel, and then placing the biological specimen coated with the gelatin in a cross-linking agent for cross-linkingtreatment so as to enable the gelatin coating layer to form a fixed insoluble cross-linked product. The biological specimen treating agent comprises gelatin, and the concentration of the gelatin ranges from 15% to 40%. The treatment method and the treatment agent for the biological specimen have the following beneficial effects: (1) pain and trauma of a patient are reduced; (2) avoiding of ethicalproblems; and (3) large-sca
