The 12 SOPs every biobank should have

High-quality biobanked samples closely resemble the biospecimen prior to extraction, with minimal modification due to collection or storage conditions. Establishment of standard operating procedures (SOPs) is crucial to avoid introducing variables into your research samples during storage and maintain the high quality required for reliable results. According to current recommendations, there are 12 SOPs that… Read article →

Maintaining biospecimen integrity during transfers

Biospecimens are usually kept in storage for the majority of their “lifetimes,” but the brief moments when they are being transferred are the moments they are most at risk. Regardless of whether the purpose for transfer is consolidation, storage reorganization or replacing damaged containers, maintaining the appropriate temperature for the type of samples and their… Read article →

Critical factors for successful molecular analysis of FFPE samples

Formalin fixation and paraffin embedding (FFPE) can impair the quality of nucleic acids obtained from tissue samples. The molecular analysis of FFPE samples is negatively affected by the low quality of analytes from FFPE samples. Taking this into consideration is important when performing successful molecular analyses. In this post, we’ll discuss how FFPE affects RNA… Read article →

Handle with care: maintaining blood samples in storage

Anyone who’s worked in a lab has likely done housekeeping on the -20°C and -80°C freezers. Carefully processing and storing samples for future use, then sorting through the frozen boxes a few years later to decide which to discard and replaced with newer ones is a perpetual cycle. Whether your biobank is in a small… Read article →
