DNA day

Let’s celebrate DNA Day!

April 25th 1953 is a day to remember. That’s the day DNA’s double-helical structure was published for the first time in a paper by James Watson and Francis Crick. The paper, printed in the journal Nature, together with papers from Maurice Wilkins and Rosalind Franklin, included evidence that the structure existed in biological systems (1,2,3)….

The plasmid purification journey – revisited!

In a previous post, my colleague Laura Mohr dazzled you with her QIAGEN time machine story. She took you on a ride through 30 years of our plasmid prep innovations that paved the way life science research is done globally. Plasmid purification still continues to be a crucial starting point for research in several labs,… Read article →

Impact of storage buffer and temperature of stored DNA on PCR amplification products

In today’s clinical and translational research, blood is one of most common biospecimens being used. Although the highest DNA yield and quality is achieved by purifying genomic DNA from freshly harvested material, regretfully most of our precious samples cannot be processed straight away. That´s why sample management is so crucial right from the very start…. Read article →

Barcodes in NGS: sample vs molecular

NGS data can be extremely complex, and technology that helps improve the accuracy of data analysis can make the difference between drawing the right conclusions or the wrong ones. Sample and molecular barcodes serve roughly the same purpose as barcodes in any other context – they’re unique identifiers that distinguish and group like items together. But unless you’ve… Read article →
