Embodiment 1

[0024] A method utilizing transmission electron microscopy to locate muscle satellite cells in the muscle of the scorpionfish Xu's, the specific steps of the method are as follows:

[0025] 1. Sampling and washing. Take a 1-year-old flat scorpionfish with a clean and sterile blade above the lateral line, close to the skeletal muscle in the middle of the dorsal fin, cut into small pieces about 1mm wide and 2-3mm long, and rinse with excess RNase-free 1xPBS buffer. The washed muscle samples were stored overnight at 4°C in 2.5% glutaraldehyde;

[0026] 2. After 0.1mol L -1 After rinsing with phosphate buffer, transfer to 1% osmic acid and fix at 4°C for 3h.

[0027] 3. Dehydration. 50% ethanol, 15-20min; 70% ethanol, 15-20min; 90% ethanol, 15-20min; 90% ethanol, 90% acetone (1:1) 15-20min; 90% acetone, 15-20min. All the above operations were carried out at 4°C. Dehydrate in 100% acetone at room temperature three times, each time for 15-20min.

[0028] 4. Embedding. Pure ac...

Abstract

The invention relates to an in situ hybridization probe primer, probe and positioning method of Xu's flat scorpion muscle satellite cells, which belong to the field of molecular biology. The primer sequences of the probe template are as SEQ.NO 1 and SEQ.NO 2, and the probe The sequence is shown in SEQ.NO 3. The invention also provides a method for using the probe to carry out in situ hybridization to localize the satellite cells of the flat scorpionfish muscle. The invention locates Xu's flat scorpion muscle satellite cells through the in situ hybridization of skeletal muscle tissue of Pax7 gene, provides theoretical and technical support for exploring the renewal and activation molecular mechanism of muscle satellite cells, and will help to further study Xu's flat Muscle growth and differentiation rules of scorpionfish; in addition, the invention has a certain application prospect in the research of gene positioning and function by in situ hybridization of muscle tissues of other fishes.

Description

technical field [0001] The invention belongs to the field of marine fish muscle growth and development, and relates to an in-situ hybridization probe primer, probe and positioning method of Xu's flat scorpion muscle satellite cells. Background technique [0002] Sebastes schlegelii is known as the "northern grouper". Its meat is delicious and has high economic value. It is an important marine economic fish and an excellent species for breeding. East China Sea. Xu's flat scorpionfish has a wide range of living temperatures and can survive the winter in deep-water cages. It is one of the few species suitable for long-term farming in deep-water cages in the north. It has been widely used in deep-water cage culture in the northern coast. [0003] Fish muscles make up 40-60% of the body weight and are the main edible part. For large economically important fishes such as the flat scorpionfish, muscle growth is the core of growth traits. Different from the muscle growth pattern ...
