Abstract
The invention discloses a preservation liquid for a pathological tissue sample. The preservation liquid is prepared through mixing by weight, 2-5 parts of potassium sorbate, 10-20 parts of industrial ethanol, 1-3 parts of glycerol, 2-3 parts of glutaraldehyde, 8.5-9.5 parts of sodium chloride, 0.6-1 part of nano-silver, 10-20 parts of citric acid and 60-100 parts of water. The sample preservation liquid is a colorless and transparent liquid, has no irritating odor and has excellent sterilization and mildew inhibition performances; the preservation liquid can effectively maintain the tissue form and color and the color of a protozoa sample, contains no volatile substances, has a lasting effect, and can effectively reduce the cost; and the preservation liquid contains no poisonous or harmful substances, is green and environmentally-friendly, and reduces the environment burden.
Description
technical field [0001] The invention relates to the technical field of pathological tissue preservation, in particular to a pathological tissue specimen preservation solution. Background technique [0002] From the operating room to the pathology department, laboratory surgery, tissue biopsy, histopathology department, gastroscopy department, etc., it is necessary to use specimen preservation solution for fixing, storing and retaining samples of tissues or cells. The existing preservation solution is mainly Fu formalin preservation solution. Formalin specimen preservation solution has a good fixation effect, which is due to the large amount of formaldehyde combined with the functional groups of the specimen protein, and after long-term storage, it further polymerizes to form paraformaldehyde. This process makes it form a moderate cross-link between protein peptide chains, which can not only kill bacteria, but also maintain the tissue shape of the specimen. However, formald...
