The invention relates to the technical field of biochemical reagents, in particular to a magnetic bead drying protection solution, a drying magnetic bead and a preparation method thereof. Wherein the magnetic bead drying protection solution, in terms of mass percentage, comprises 5-15% cellobiose, 0.005-0.02% Tween 20 and 0.05-0.2% sucrose ester, and the balance is water; the The HLB value of the sucrose ester is 15. The magnetic bead drying protection solution provided by the present invention can protect the performance of the dried hydroxyl magnetic beads to the maximum extent, and the dried hydroxyl magnetic beads can be stored and transported at room temperature, and the storage period is long, which is helpful for the application in the microfluidic chip. application. |
