Repriming Chips Note: Buffer tubes filled with 1X DNA sample buffer or water should be placed into the instrument while priming or washing chips. • Touch the Unload Chip button on the Home screen to open the instrument door. Place the chip into the instrument. • Close the chip door securely and choose the corresponding assay. • Touch the Prime button on the Home screen to reprime the chip. Washing and Repriming Chips • Touch the Unload Chip button on the Home screen to open the instrument door. • Place the chip into the plastic storage container. The sipper should be submerged in the fluid reservoir. • Remove the reagents from each well of the chip using vacuum. • Each active well (1, 3, 4, 7, 8, and 10) should be rinsed and aspirated twice with water (Milli-Q® or equivalent). Do not allow active wells to remain dry. • Add 100 µL of DNA Chip Storage Buffer to each active well (1, 3, 4, 7, 8, and 10). • Place the chip in the LabChip GX Touch/GXII Touch instrument. Ensure that a Buffer Tube with 750 µL of water (Milli-Q® or equivalent) is in the buffer slot. • Close the chip door securely. • Touch the Wash button on the Home screen. The Wash screen opens (Figure 18).

Wash screen

After the completion of the wash cycle return the chip to the chip container ensuring the sipper is immersed in fluid. • Thoroughly aspirate all fluid from the chip wells using a vacuum line. • Ensure that each active well (1, 3, 4, 7, 8, and 10) is rinsed and aspirated twice with water (Milli-Q® or equivalent). Do not allow active wells to remain dry. • Add Gel-Dye solution to chip wells 3, 7, 8, and 10 using a Reverse Pipetting Technique as shown in Figure 17. • Add Marker (green cap ) to chip well 4. Use 50 µL for 96-well or 120 µL for 384-well plate analysis. Please note that the marker well may need to be replenished if the chip is in idle mode on the instrument for an extended period of time. • Place the chip into the LabChip GX Touch/GXII Touch instrument. • Close the chip door securely. • Touch the Run or Prime button on the Home screen

Removing an air bubble

• If air bubbles are not dislodged after a reprime, apply a vacuum to the sipper. Perform this by filling all active wells with 100 µL of Chip Storage Buffer. Then suction the sipper with a vacuum line as shown in Figure 19 until droplets of fluid flow out from the sipper. When suctioning the sipper, be careful not to bend or break the sipper. To facilitate this, cut the end of the pipette tip attached to the vacuum line to widen the mouth.
