Sometimes chromatography is not fun; deciphering the plumbing path, modules not always in the most convenient place and finally having to determine how the software works to perform the run and analyse your results. Then, when everything is running smoothly, the person with all this knowledge moves on and you are back at the start. Chromatography would be more enjoyable if it was more intuitive and assisted you in these tasks, wouldn’t it?

Watching this video, I realize why I didn’t actually learn anything until I started graduate school. Curiosity was a sin in my primary school. The teacher taught and the pupils needed to listen.

This is how classes should be run. This is what science is about!

Bio-Rad Laboratories, Inc. recently announced the addition of the mouse genome to its PrimePCR assays for quantitative real-time PCR (qPCR). Bio-Rad’s PrimePCR assays are the industry’s only real-time PCR primers that have been experimentally validated to ensure performance.

“Based on the qPCR data I have seen in our lab and from researchers looking for support, I learned to appreciate the value of fully validated assays,” said Dr. Jan Hellemans, co-CEO of Biogazelle, a qPCR data analysis and services company he cofounded with Prof. Jo Vandesompele in 2007 as a privately held Ghent University spin-off. Hellemans and Vandesompele were also coauthors of the MIQE guidelines (minimum information for publication of quantitative real-time PCR experiments) established to promote high-quality data from qPCR experiments (Bustin et al. 2009).

Commercial providers have traditionally used software to facilitate the design of qPCR assays. While these algorithms detect sequences such as single-nucleotide polymorphisms and secondary structure that may impair or bias amplification, they do not guarantee that the assay will work in the lab. To validate an assay, users must still test the resulting PCR primers for efficiency and specificity with the target sequence.

Meeting the MIQE Guidelines through Full Wet-Lab Validation
Bio-Rad collaborated with Biogazelle to design, optimize, and experimentally validate SYBR® Green-based gene expression assays for the mouse genome. PCR primer pairs for each mouse transcript were designed following strict guidelines on maximum transcript coverage, minimal overlap with known SNPs, and spanning large introns where possible.

In accordance with the MIQE guidelines, every assay was wet-lab validated following strict assay performance standards for amplification efficiency, specificity, sensitivity, and linear dynamic range. Assay specificity was confirmed using next-generation sequencing (NGS). This approach yielded validated assays for more than 90 percent of the mRNA transcriptome.

“Using Bio-Rad’s PrimePCR assays now allows users to run high-quality MIQE-compliant assays without having to spend the effort performing the lab validation themselves,” said Hellemans.

Additionally, the PrimePCR mouse assays are:

  • Expertly curated — predesigned pathway and disease plates curated by Thomson Reuters for canonical pathways and related collections help researchers identify and investigate key targets
  • Customizable — easy-to-use plate configurator allows users to lay out assays on a plate exactly as they choose or use a suggested plate layout template
  • Fully integrated — full integration with CFX real-time PCR systems and data analysis software streamlines data collection and analysis

Although hundreds of genome projects in dozens of species have been conducted in the past decade, tens of millions of new genes remain to be discovered in the deep ocean alone. The great abyss is literally teeming with unknown species and many of them have the potential to be of significant value to their human cousins in the world above.

Consider this: Despite the limited amount of research done so far, scientists have already discovered bacteria which are capable of degrading highly toxic compounds on the seabed floor. If their power is harnessed properly, the bacteria may eventually be used as ecological biosensors or as tools to detoxify harmful substances derived from human activity.

According to Jesús María Arrieta, CSIC researcher at the Mediterranean Institute for Advanced Studies

The number of marine species used as a source of genes with commercial interests grows at a rate of 12% per annum

This fast pace of discovery will eventually open the door to multiple biotechnological applications in fields such as bioenergy, food or cosmetics.

It is in that spirit that a team of Spanish researchers, coordinated by the Spanish National Research Council (CSIC), has started to sequence the genome of the global deep ocean. The scientists havve chosen to go deeper than previous studies, penetrating waters between 200 to 4,000 meters deep in order to discover viruses, bacteria and protists that inhabit the mysterious ocean depth.
