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.

Reaction Setup


Reaction Setup

 

Component Volume
LyoBead 0.75 µl (volume of one LyoBead)
Primers and probes x µl
Template/Sample extract y µl
Water fill up to 20 µl total reaction volume

Briefly tap-down or gently spin down before opening the reaction tubes.

Add primers and probes as well as template/sample extract. LyoBeads are dissolved within 1-2 minutes at room-temperature even without mixing. Close the PCR tubes, vortex or mix briefly, spin down and start the PCR.

*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. 

 

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.

 

Storage

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.

 

 

img-faqsFAQ`s

 

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. 

Fidelity of DNA synthesis by the Thermus aquaticus DNA polymerase.
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!
