Effective genomic DNA removal – crucial for accurate gene expression analysis

Whether you are working with formalin-fixed, paraffin embedded (FFPE) tissue or normal tissue samples, the elimination of genomic DNA (gDNA) from your RNA preps is crucial to obtain reliable results in gene expression analysis, especially if you want to determine the gene expression pattern in a specific cell or under specific conditions. Possible consequences of… Read article →

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 →
