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 →

Expert talks how to purify more DNA from challenging tissues

Mechanical and enzymatic lysis both have their drawbacks when isolating genomic DNA from solid tissue samples. While mechanical disruption tends to provide high yields from tissue samples, it does damage the nucleic acids. Enzymatic lysis, like Proteinase K digestion, allows extraction of nucleic acids without damage, but requires long incubation times and provides lower yields… Read article →
