SELECTION GUIDE: 8-strip PCR TUBES

White vs. Clear:

White

• Direct significantly more signal back to the qPCR instrument's detector compared to traditional clear plates (the improved signal reflection ensures that even the lowest levels of fluorescence are detected)
• The white well walls stop the signal from passing through to the cycler block, where it can be inconsistently reflected or absorbed, leading to increased noise levels in detected fluorescence. This keeps variations in the cycler block from affecting qPCR data
• Our white PCR plastics increases sensitivity, reduces variability and increases the signal-to-noise ratio within the qPCR assay

Clear

• Allows to verify pipetting steps right after each pipetting action, as you can see the reagent added into the well as you intended
• Suitable for most applications

Standard Profile vs. Low Profile

Standard-profile (full-height: around 21.0 mm) wells

• “Standard” relative to the low-profile plates
• Fit in most classical thermal cyclers and real-time PCR detection systems (ex. Bio-Rad's iCycler®, iQ™ series real-time PCR detection systems, and Applied Biosystems' regular PCR systems and DNA sequencers)
• Allow large reaction volumes
• Tubes reduce risk-splashing caused by cross-over contamination, minimizing the risk of well-to-well cross contamination

Low-profile (around 15.5 mm) wells

• The newer design reduces the potential for condensate formation and offers advantages for light capture in fluorescence assays, low-volume reactions, and fast PCR
• Recommended for newer instruments (ex. Bio-Rad's C1000 Touch™ and S1000™ thermal cyclers, CFX series real-time PCR detection systems, and Applied Biosystems' fast PCR systems)
• Tubes reduce dead space and increase PCR efficiency

**Please consult the manual of the PCR system, if necessary or ask us.

Instruments with adjustable lids can usually use both standard-profile and low-profile wells.

These instruments include Bio-Rad's 1000-series and DNA Engine® series thermal cyclers.

**Some systems require standard profile or low-profile tubes only.
