Embodiment 1

[0029] A method for rapidly separating hepatocytes of carps, comprising the following steps:

[0030] (1) Grass carp is anesthetized with ethyl m-aminobenzoate methanesulfonic acid at a concentration of 100 mg / l. After anesthesia, the back artery is cut off to let blood, and then the abdomen of the fish is placed upward on ice, and its abdomen is disinfected with 75% alcohol , cut the belly of the fish along the midline of the abdomen to take out the liver, and put the liver into the pre-cooled Hanks balanced salt solution;

[0031] (2) Take a 1cm×2cm liver block from the liver in step (1), remove the membrane, sinusoids and connective tissue on the surface of the liver block, then cut it into 1mm thick liver slices, and cut the liver slices with pre- Rinse off with cold Hanks' Balanced Salt Solution;

[0032] (3) Mince the liver slices rinsed in step (2) to obtain liver fragments, transfer the liver fragments to a centrifuge tube, and add 30ml of Hanks’ balanced salt solutio...

Embodiment 2

[0037] A method for rapidly separating hepatocytes of carps, comprising the following steps:

[0038](1) Grass carp is anesthetized with ethyl m-aminobenzoate methanesulfonic acid at a concentration of 100 mg / l.

Abstract

The invention discloses a rapid separating method for cyprinid fish hepatocytes. The rapid separating method comprises the steps of chopping fish livers to obtain fish liver fragments and adding a Hank's balanced salt solution into the fish liver fragments, and performing oscillation and centrifugation to obtain precipitates; adding digestive juice consisting of CaCl2, bovine serum albumin, collagenase, dispase, a trypsin inhibitor, deoxyribonuclease I and the Hank's balanced salt solution into the precipitates, and performing oscillation, beating and sieving with a cell strainer to obtain large tissue precipitates and a cell suspension; adding a cleaning solution consisting of the CaCl2, the bovine serum albumin and the Hank's balanced salt solution into the large tissue precipitates, andperforming beating and sieving with the cell strainer to obtain a cell suspension, repeating the step for 3 times to obtain a merged cell suspension, performing centrifugation on the merged cell suspension to obtain cell precipitates, adding the cleaning solution into the cell precipitates, and performing beating and centrifugation to prepare primary hepatocytes. The method effectively solves theproblems that cost is high and the sizes of fishes are required to be large due to the fact that the separating time is long and multiple enzyme preparations are required by employing an existing method

Description

technical field [0001] The invention relates to the technical field of fish liver cell separation, in particular to a rapid separation method for carp fish liver cells. Background technique [0002] The liver is one of the most important organs in the body. It has the functions of digestion, metabolism and immune regulation, and is the target organ of harmful environmental factors. Therefore, primary cells isolated from the liver are often used as the object of research in pharmacology, toxicology, immunology, cell biology and endocrinology. Fish hepatocytes have also been isolated and cultured, and they have been used in the study of fish liver structure and function, such as temperature acclimation of fish, cell senescence, cell interaction, lipoprotein metabolism, nutrient metabolism and endocrine regulation, vitellogenin Synthesis, hormone receptor expression, metabolism and toxicology studies of cytochrome P450. [0003] The perfusion method is often used to isolate h...
