Embodiment 1
[0026] Take fresh pig embryos (including placenta), wash them with pure water, and use an electric mixer to crush the embryos and placenta into a paste (porridge). Pass the sample through a 60-mesh sieve and collect the filtered sample. Add antioxidants (tea polyphenols (Victor powder) 0.02%, tertiary butyl hydroquinone TBHQ0.01%) and lyoprotectants (sodium alginate 0.5%, Tween-80 0.5%, mannitol 4% , alanine 1%, glycine 1.5%), carry out low-temperature high-pressure homogenization after. Homogenization conditions: pressure 40Kg / cm 2 , the processing speed is 40L / hr, the homogenate volume is controlled at 1L each time, the homogenate time is 5 minutes (depending on the homogenate flow rate and sample volume), and the temperature is controlled at 0°C. Divide the homogenized samples into freezing trays, the height of the samples should not exceed 5cm, and freeze-dry them in a vacuum freeze dryer. The freeze-drying conditions are: pre-cooling at -50° C. for 1 hour; vacuuming, w...
Embodiment 2
[0029] Take fresh pig embryos (including placenta), wash them with pure water, add crushed ice made of pure water, and use an electric mixer to crush the embryos and placenta into a paste (porridge) shape. Pass the sample through a 60-mesh sieve and collect the filtered sample. Add antioxidants (tea polyphenols (Victor powder) 0.02%, tertiary butyl hydroquinone TBHQ 0.005%) and lyoprotectants (sodium alginate 0.1%, Tween-80 0.01%, mannitol 2%, alanine 2%, glycine 1%), add crushed ice made of citrate buffer, and carry out low temperature and high pressure homogenization. Homogenization conditions: pressure 60Kg / cm 2 , the processing speed is 60L / hr, the homogenate volume is controlled at 5L each time, the homogenate time is 10 minutes (depending on the homogenate flow rate and sample volume), and the temperature is controlled at 4°C. Divide the homogenized samples into freezing trays, the height of the samples should not exceed 5cm, and freeze-dry them in a vacuum freeze drye...
Embodiment 3
[0032] The conventional animal embryo freezing-thawing process and the process of the present invention are used to produce 1 kg of pig embryos, and the recovery rate and activity of active ingredients are compared. Porcine placenta activity was detected by lymphocyte rosette activity. The detection method is as follows:
[0033] Peripheral blood mononuclear cells of healthy people were separated with lymphatic separation fluid according to conventional methods, stained with 1% trypan blue to detect cell viability (should be >95%) and counted cells. Adjust the cell number to 2 x 10 with calf serum 6 / mL. Take 200 μL of cell solution into test tubes, divide them into freeze-thaw control group and homogenate group, and add samples to the final concentration of (1×10 -2 mg / L) (the sample was diluted with cell culture medium and sterilized by filtration). Water bath at 37°C for 90 minutes; wash sheep red blood cells with normal saline, and adjust the number of cells to 2×10 8...
