If you’re interested in generating proteomics data but your organism of interest doesn’t have a sequenced genome to use as a reference database, it is straightforward and useful to collect a transcriptome instead.

Cells can be highly motile, moving in and out of a microscope’s field of view. Understanding complex life cycles is difficult without continuous observation. To overcome this challenge, we’ve developed a 3D-printed microchamber device to confine cells for long-term visualization.

Quantifying movement is a powerful window into cellular functions. However, cells can generate movement through a variety of complex mechanisms. Here, we generate a flexible framework for comparing an especially variable type of motility: cellular crawling.

Long protrusions from several microalgal species appear to help cells move, capture prey, transport mitochondria and chloroplasts, and more. Are they filopodia that evolved abilities more like other actin- or microtubule-based structures, or are they something new?

This pub details a process for phage amplification and concentration, DNA extraction, and HPLC and MS analysis of phage nucleosides. We optimized the approach with model phages known to use non-canonical nucleosides in their DNA, but plan to apply it for other phages.

A workflow orchestration framework can streamline repeatable tasks and make workflows broadly usable. From several options, we chose Nextflow due to the ease of deploying across platforms, vibrant nf-core community, and ability to manage and monitor workflows with Nextflow Tower.

We struggled to isolate enough phage mRNA for HPLC as we searched for new nucleoside chemistries. Ribodepleting the abundant extracted rRNA introduced contaminating DNA, and we were still left with more bacterial mRNA than phage transcripts. We suggest an alternative approach.
