One of the main challenges for cell-free DNA analysis is the limited amount obtained from any bodily fluid, which affects the number and type of tests that can be performed. The TruePrime™ Apoptotic Cell-Free DNA Amplification Kit provides the solution to this issue by exponentially amplifying cell-free DNA derived from apoptosis cell-death mechanism (160-170 bp).
The TruePrime™ Apoptotic Cell-Free DNA Amplification Kit combines the novel TruePrime™ DNA amplification technology, with key novel steps of cell-free DNA pre-treatment, composed of an end-repair + dA tailing reaction and ligation of hairpin-adaptors, which enables the efficient amplification of apoptotic cell-free DNA by TruePrime™ following the rolling circle DNA amplification method.
- Excellent sensitivity – down to picograms of input material
- High amplification yields
- Flexibility, up to 150 ng or 50 µl of cfDNA input
- Error-free amplification due to the use of high-fidelity Phi29 DNA pol
- No artefacts derived from random synthetic primers
- Streamlined workflow and reduced hands-on time
The TruePrime™ apoptotic cell-free DNA amplification kit uses a novel multiple displacement amplification method to achieve accurate DNA amplification from cell-free DNA obtained from plasma, serum, urine, CSF or any other bodily fluid. TthPrimPol generates primers on the hairpin-adaptors that are extended by Phi29 DNA polymerase. The strong strand displacement capacity of Phi29 DNA polymerase allows TthPrimPol to synthesize new primers on the new hairpins generated, resulting in exponential isothermal DNA amplification.

The TruePrime™ Apoptotic Cell-Free DNA Amplification Kit is shipped in dry ice. Upon receipt, the kit should be stored immediately at -20ºC in a non-frost-free (constant-temperature) freezer. If stored correctly, the product can be kept for at least 6 months after shipping without displaying any reduction in performance. For longer periods, store the kit at -80ºC. Avoid repeated free-thaw cycles if possible.
