Embodiment 1
[0051] A method for cleaning the sampling head of a chip spotting instrument of the present invention is carried out according to the following steps:
[0052] (1) Prepare two reagents in advance:
[0053] A: 3% (V / V) Hellmanex III aqueous solution (a cleaning agent produced by HELLMA Analytics, Germany) and 5% (W / V) SDS aqueous solution,
[0054] B: 75% (V / V) isopropanol aqueous solution.
[0055] (2), add 300ul of A solution in the No. 1 hole and the No. 3 hole of the sample strip, and add 300ul of the B solution in the No. 2 hole and the No. 4 hole;
[0056] The cleaning process is:
[0057] (1) Wash the inner wall of the sampling head with purified water 10-15 times (250ul each time), and the outer wall 2 times (2 seconds each time),
[0058] (2) The sampling head absorbs 80ul of liquid A in the No. 1 hole of the sample loading strip, and soaks the sampling head in the remaining liquid A in the No. 1 hole for more than 10 minutes;
[0059](3) Wash the inner wall of the...
