qPCR Probe LyoBeads
qPCR Probe LyoBeads
are ready-to-use freeze-dried master mixes that contain all components necessary for a rapid, sensitive and reproducible detection and quantification of DNA and cDNA. qPCR Probe LyoBeads are shipped and stored simply at room-temperature. This provides a more cost efficient and ecological distribution compared to other master mixes.
All necessary components for PCR are already included in one LyoBead: an engineered DNA polymerase, an optimized reaction buffer and ultrapure dNTPs. Only primers and probes need to be added. A hot-start formulation of the included DNA polymerase prevents false amplification during the reaction set-up.
All LyoBeads are pre-dispensed in PCR-strips or PCR-plates. Available formats can be seen here.

*Typically, the annealing temperature is about 3-5°C below the calculated melting temperature of the primers used.
More product description
Pre-dispensed qPCR Probe LyoBeads
Each qPCR Probe LyoBead is equivalent to a 20 µl PCR reaction. qPCR Probe LyoBeads can be pre-dispensed in 8- well PCR strips or 96-well plates. Available formats can be seen here.
qPCR Probe LyoBeads are tested in real-time qPCR. The product demonstrates linearity of amplification over a specified serial dilution of human genomic DNA. DNA polymerase activity: DNA polymerase activity has been monitored and adjusted to a specific DNA polymerase activity using an artificial DNA template and a DNA primer. Enzyme-concentration has been determined by proteinspecific staining. Please inquire more information at firstname.lastname@example.org for the lot-specific concentration. No contamination has been detected in standard test reactions.
Costly cooling chains and storage at -20°C are no longer necessary: qPCR Probe LyoBeads are shipped and stored simply at room-temperature in a dry place. Once opened, the surrounding air humidity is ideally less than 30%.
Composition / Content of the Product
qPCR Probe LyoBeads contain all the components necessary for PCR, including a hot-start formulated Taq DNA polymerase and an optimized buffer including ultrapure dNTPs.
Which DNA polymerase is included in these LyoBeads?
The LyoBeads contain our best performing, hot-start formulated, engineered Taq DNA polymerase. We have chosen this DNA polymerase as it is best suited for multiplex PCRs, pathogen detection qPCRs and all kinds of probe-based qPCRs.
The enzyme’s fidelity is comparable with the wild-type Taq DNA polymerase as described in the reference below.

Biochemistry 1988; 27(16): 6008–6013. K. R. Tindall, T. A. Kunkel.
Can you also produce LyobBeads containing other DNA polymerases?
Yes we can. Currently we are working on qPCR LyoBeads containing GreenDye and RT-qPCR Beads containing a Volcano2G mutant for you. On request we can also discuss the production of other LyoBeads with you. Please contact us should you be interested!
