Engineering of a DNA Polymerase for Direct m6A Sequencing
2017
Methods for the detection of RNA modifications are of fundamental importance for advancing epitranscriptomics. N6-methyladenosine (m6A) is the most abundant RNA modification in mammalian mRNA and is involved in the regulation of gene expression. Current detection techniques are laborious and rely on antibody-based enrichment of m6A-containing RNA prior to sequencing, since m6A modifications are generally "erased" during reverse transcription (RT). To overcome the drawbacks associated with indirect detection, we aimed to generate novel DNA polymerase variants for direct m6A sequencing. Therefore, we developed a screen to evolve an RT-active KlenTaq DNA polymerase variant that sets a mark for…
Performance comparison of two whole genome amplification techniques in frame of multifactor preimplantation genetic testing
2018
Purpose To compare multiple displacement amplification and OmniPlex whole genome amplification technique performance during array comparative genome hybridization (aCGH), Sanger sequencing, SNaPshot and fragment size analysis downstream applications in frame of multifactor embryo preimplantation genetic testing. Methods Preclinical workup included linked short tandem repeat (STR) marker selection and primer design for loci of interest. It was followed by a family haplotyping, after which an in vitro fertilization preimplantation genetic testing (IVF-PGT) cycle was carried out. A total of 62 embryos were retrieved from nine couples with a confirmed single gene disorder being transmitted in t…
Rapid PCR-based test for identifying Candida albicans by using primers derived from the pH-regulated KER1 gene.
2006
A PCR-based method in combination with a simple, reliable and inexpensive DNA extraction procedure for rapid detection of Candida albicans clinical isolates is described here. The extraction protocol is based on a combination of chemical (NaOH and detergents) and physical (boiling) treatments, thus avoiding many of the problems inherent in the currently available DNA extraction protocols (basically the use of expensive and/or toxic chemical reagents), and may be useful for daily clinical routine. The PCR-based system described here uses a single pair of primers (SC1F and SC1R) deduced from the C. albicans-specific KER1 gene sequence. These primers amplify a 670-bp fragment of the KER1 gene.…
Application of whole genome amplification for forensic analysis
2006
Abstract Fundamental to most forensic analyses is the availability of genomic DNA of adequate quality and quantity. To perform a multitude of genetic analyses and assays requires a sufficiently large amount of template. However, DNA yield from forensic samples is frequently limiting the extent of genetic typing. A possible solution to overcome this “bottleneck” of forensic and paleoarcheological DNA analyses could be the amplification of the entire genomic DNA prior to locus specific PCR analysis. Whole Genome Amplification appears to be a promising tool to obtain sufficient DNA amounts from forensic samples of limited quantity.
