[0029] The invention provides a blood sample pretreatment method, which has simple operation, few steps and saves time.
[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0031] The first step is to take a clean test tube and add acetonitrile solvent and plasma to the test tube. The volume ratio of plasma to acetonitrile is greater than or equal to 1:3. Under the action of the acetonitrile solvent, the contaminated proteins in the plasma separate to form flocs. The catenin is attached to the floc in an ionic state, and the floc is in the solution in the test tube. In this embodiment, the volume of plasma ranges from 75 μL to 100 μL. Compared with the prior art, the volume of plasma required in this embodiment is very small.
[0032] In this embodiment, the volume ratio ...
