Abstract

The invention relates to a paraffin wax slicing method of ocean shellfish oocytes, comprising the steps of fixing, dehydration, clarity, waxdip, imbedment, slicing, dyeing, mounting, and the like. Theparaffin wax slicing method is characterized by solving the problem of the difficult waxdip and imbedment of the ocean shellfish oocytes due to small volume, improving a hematoxylin-eosin dyeing method and obtaining favorable slicing and dyeing effect. The paraffin wax slicing method is simple and easy to operate without adding instruments or equipment, can carry out paraffin wax slicing on mostof the ocean shellfish oocytes with the diameters more than or equal to 40 micrometers, transition steps are carried out among the dehydration, the clarity and the waxdip of the steps and mostly in two-step processing so that a reagent gradually and completely enters a tissue and is preserved in the original structure of the tissue in an intact way so as to provide an effective researching means for shellfish fertilization and early embryonic development research.

Description

technical field

[0001] The invention relates to a paraffin sectioning method, in particular to a paraffin sectioning method suitable for marine shellfish egg cells with small egg diameters. Background technique

[0002] Paraffin section technology is one of the important research methods of fertilization cytology. It has mature technology, stable method, low cost, convenient observation, and has the advantages of well-preserved tissue structure and clear image contrast, which can be clearly seen under light microscope. The changes in the external morphology and internal structure of fertilized eggs, especially the elongation and elongation of the spindle body and the changes in the nuclear membrane when the pronuclei of the two sexes combine, have unique advantages that are different from compression, transmission electron microscopy and fluorescence microscopy. Paraffin section technique has been widely used in fish fertilization cytology research. However, due to the smal...
