Abstract

The invention, relating to a molecular biology technology, particularly discloses a kit for rapid detection of red tide algae in a natural water sample and a usage method thereof. The kit comprises a filter membrane, a reagent and a sample to be detected, wherein, the reagent comprises 0.05-0.2 mL of ddH2O, 0.2-0.4 mL of 95% ethanol, 1.5-2.5 mL of 20*SET buffer, 600-700 mu l of 5*SET buffer, 400-500 mu l of 1* SET buffer and 10-15 mu l of FITC labeled oligonucleotide probe solution. The kit is convenient to carry, and can be carried to the ships for detecting red tide algae in the natural water sample at any time. Simultaneously, the kit has the advantages of simple operation, time saving, and effectiveness, and has good application and market demands.

Description

technical field [0001] The invention relates to molecular biology technology, in particular to a kit for rapidly detecting red tide algae in natural water samples. Background technique [0002] Red tide (red tide) generally refers to the phenomenon of discoloration of sea water due to the excessive reproduction of marine plankton (mainly dinoflagellates and diatoms). Strictly speaking, red tide is a natural phenomenon, but since the 1970s, there have been more and more reports about red tide. According to incomplete statistics, in 1972 and 1998, there were There are 360 ​​recorded red tides. The frequency of red tides has increased significantly, the scale of occurrence and the degree of damage have become increasingly serious, which not only affects the marine ecological environment of our country, but also causes huge losses to marine fisheries. What's more serious is that the frequent outbreaks of red tides make the species of red tide algae expand rapidly around the wo...
