Why UV-Vis and Fluorescence Can Give You Different Concentration Values
UV-Vis measures all molecules that absorb at 260 nm, while fluorescence assays mainly detect the target nucleic acid selected by the dye. Compare both values alongside A260/A280 and A260/A230 ratios to identify contamination, low-concentration measurement limits, or handling errors. Agreement between the methods indicates confidence in the sample results, while a consistent gap helps you decide whether to repurify, adjust input, or use a more sensitive method.
Preparing a manuscript involves plenty of work beyond writing: author lists, affiliations, disclosures, funding statements, references, and figure preparation. This post covers the tools I use to handle that admin, why I choose them over AI, and how they help. If you’re first author on a multi-author paper, this is for you.
You’ve moved your cells into serum-free medium…and they look sparse and sad. Whatever pushed you to drop fetal bovine serum the temptation now is to blame the medium and start reformulating. But before you spend any more of your precious grant money, read this article.
When buying antibodies, it’s crucial to verify the true source and validation of the reagent rather than relying on brand names alone. In this article, I’ll explain how to check clone details, application-specific evidence, lot numbers, and supplier accountability to avoid costly failures and ensure better reproducibility.
Onboarding Empower™ Users is most effective when training focuses first on core terminology, compliance, and daily workflows using your lab’s real data. Teaching less initially builds a solid foundation, enabling quicker, confident analyst independence. Competence, not time, should guide when to expand training to advanced topics.
Microscopy & Imaging
Optical microscopy has always been restricted by the diffraction of light. Because conventional widefield and confocal microscopes cannot resolve structures substantially smaller than about 200nm laterally, they miss critical signaling compartments and nanoscopic organization. Newer super-resolution technologies, such as stimulated emission depletion (STED), structured illumination microscopy (SIM), and photoactivated localization microscopy (PALM), solve this problem…
