Embodiment 1
[0029] Make a kit for rapid detection of algae Schwannella according to the following formula:
[0030] Reagent A: 0.1M NaCl, 10mM Tris.Cl (pH8.0), 1mM EDTA (pH8.0), 5% Triton X-100
[0031] Reagent B: 10mg / ml lysozyme, 10mM Tris.Cl (pH8.0)
[0032] Reagent C: 5.0μl 10×PCR Buffer, 0.5μl Taq (5U / μl), 35.5μl ddH 2 o
[0033] Reagent D: 4.0μl dNTP (2.5mM each), 3.0μl MgCl 2 (25mM),
[0034] 20pm VP 03 , 20pm VP 04
[0035]Reagent E: 50×TAE
[0036] Reagent F: agarose (1%) + ethidium bromide (0.5 μg / ml)
[0037] Follow the procedure below for testing:
[0038] 1. Sample processing and DNA extraction: Take about 0.1-0.5 grams of fish tissue, add 400 μl of reagent A to the sample, mash it with a sterilized toothpick, centrifuge at 12,000 g for 2 minutes, discard the supernatant, and re-use 350 μl of reagent A and 50 μl of reagent B. Suspend the precipitate and mix well. Place at room temperature for 5 minutes, then in a water bath at 100°C for 5 minutes. Cool to r...

[0045] Reagent A: 0.3M NaCl, 10mM Tris.Cl (pH8.0), 1mM EDTA (pH8.0),
[0046] Reagent B: 5mg / ml lysozyme, 10mM Tris.Cl (pH8.0)
[0047] Reagent C: 2.5μl 10×PCR Buffer, 0.25μl Taq (5U / μl), 35.5μl ddH 2 o
[0048] Reagent D: 2.0μl dNTP (2.5mM each), 1.5μl MgCl 2 (25mM),
[0049] 10pm VP 03 (0.5μl), 10pm VP 04 (0.5μl)
[0050] Reagent E::50×TAE
[0051] Reagent F: agarose (1.2%) + ethidium bromide (0.8 μg / ml)
[0052] Follow the procedure below:
[0053] 1. Sample Processing and DNA Extraction
[0054] Take about 0.1-0.5 g of fish tissue, add 200 μl of reagent A to the sample, mash it with a sterilized toothpick, centrifuge at 12,000 g for 2 minutes, discard the supernatant, resuspend the pellet with 150 μl of reagent A and 50 μl of reagent B, and mix well. Place at room temperature for 5 minutes, then in a water bath at 100°C for 1 minute. Cool to room temperature and centrifuge at 12000g fo...
