Assay warnings and precautions 1
Assay warnings and precautions
Follow universal precautions for laboratory and assay procedures, and waste disposal.
Follow federal, state, local, and within-country regulations. See Appendix G, ʺSafetyʺ
on page 87.
Before you begin, go to Appendix A, ʺWorkflow and practicesʺ on page 57 for specific
setup instructions, and equipment and technique illustrations and Appendix C,
ʺThermal cycler protocolsʺ for specific thermal cycler protocol set ups.
For additional specific warnings, precautions, and procedures, refer to
ʺDocumentation and supportʺ on page 90:
Precautions
The physical and toxicological properties of the products in this kit(s) have not been
thoroughly investigated. Follow prudent laboratory practices and use general
laboratory safety equipment (eye protection, lab coat, and lab gloves) and good
personal hygiene when working with these or any laboratory reagents. Refer to the
Safety Data Sheet for more information.
Proper laboratory practice is necessary as previously amplified PCR product is the
most likely potential source of contamination. We strongly recommend two separate
work areas be used to minimize the risk of cross contamination during the assay
procedure. It is essential to adhere to workflow recommendations. PCR reactions
should be set up in the Pre-PCR Area only. Personnel should not re- enter the Pre-PCR
Clean Area once exposed to PCR products without first showering and changing into
clean clothes.
Carefully reading and following the protocol as written is essential. Substitution of
reagents and not following detailed procedures are not recommended as your results
could be suboptimal.
Pre-/Post-PCR
• Follow standard procedures and single-direction workflow for the Pre-PCR
laboratory area.
• Use dedicated equipment for each area (e.g., thermal cyclers, microfuges, pipettes
and tips, ice buckets, etc.).
• Place all reagents and master stocks in use area. Do not move equipment between
Pre- and Post-PCR Rooms, e.g., ice buckets, pipettes, etc.
• Use separate copy of assay procedure in Pre- and Post-PCR areas.
• Follow procedures for re-entry of Pre-PCR Clean Room from post-PCR.
• If pre-PCR work is done in a laminar flow hood or PCR cabinet, then additionally
ensure:
– laminar flow hood is always on.
– UV lamp is on when not in use.
Do not
• Use kit after its expiration date.
• Mix and match reagents from other reagent kits.
• Use reagents after more than four freeze-thaw cycles.
• Use any water other than nuclease-free water supplied with the CytoScan Reagent Kit.
• Reuse a plate seal.
