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 in a dry place. This provides a more cost efficient and ecological distribution compared to other master mixes. All necessary components 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.

For non-dispensed LyoBeads, aliquote them with a metallic tweezer into individual reaction tubes or wells as it is shown in this short video.

For already pre-dispensed Lyobeads, briefly tap-down or gently spin down before opening the reaction tubes.

Add primers and probes as well as template/sample extract. Close the PCR tubes, vortex or mix briefly, spin down and start the PCR.

Detailed product description


Pre-dispensed qPCR Probe LyoBeads


Each qPCR Probe LyoBead is equivalent to a 20 ¬Ķl PCR reaction and can either be provided pre-dispensed on demand or non-dispensed. qPCR Probe LyoBeads can be pre-dispensed in¬† 8- or 12-strip PCR tubes (upper image), single PCR tubes or in 96-well plates (as you can see in this video here). Non-dispensed qPCR Probe LyoBeads are provided in micro tubes with screw cap (as shown in the lower image).



Handling of non-dispensed qPCR Probe LyoBeads


It is recommended to use a metallic tweezer to aliquote the qPCR Probe LyoBeads as shown in this short video.


Quality Control

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 info@mypols.de for the lot-specific concentration. No contamination has been detected in standard test reactions.



Costly cooling chains and storage at -20¬įC 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‚Äď6013. K. R. Tindall, T. A. Kunkel.



How can I avoid electro static charge of the LyoBeads?


We recommend to use metallic tweezers for distributing the LyoBeads into the reaction-tubes. Also anti-static equipment and gloves may prevent electro static problems. It also helps to stand the PCR tubes or plates on a metallic surface.


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!
