Tools and Handling
• Always follow the GLP-rules established in the laboratory.
• Always wear gloves when handling chips to prevent contamination.
• When pipetting sample, use non-filter pipette tips that are of adequate size.
Pipette tips that are too large will lead to poor quantitation accuracy.
• Change pipette tips between steps to avoid cross-contamination.
• Always insert the pipette tip to the bottom of the well when dispensing
liquid. Placing the tip at the edge of the well leads to bubbles and poor
results. Holding the pipette at a slight angle will ensure proper dispensing
of the liquid.
• Use a new syringe and electrode cleaner with each new kit.
