Choosing between qPCR or RNA-seq often means balancing speed and scope. qPCR is quick but limited to a small set of pre-selected genes, while RNA-seq offers a full transcriptome view but you typically wait weeks to get results. This article explores how 3′ RNA-seq bridges that gap, delivering genome-wide insights in days.
Find out how to detect low-affinity protein binding without using SPR. The Octet® R8e BLI system bridges the gap between speed, simplicity, and sensitivity, transforming drug discovery workflows.
qPCR Primer design involves a five-stage process ensuring specific, efficient amplification. Key steps include checking for validated primers, choosing detection chemistry, setting primer parameters, addressing mRNA-specific needs, and deciding on singleplex or multiplex assays. Proper design reduces errors and improves assay success, especially when targeting mRNA or multiplexing. This practical guide helps researchers create reliable primer sets tailored to their experimental goals.
This guide on qPCR analysis outlines the essential workflow from raw Cq values to reliable gene expression results. It covers defining Cq units, organizing data, validating assays with standard curves, normalizing with stable reference genes, calculating fold changes using ΔΔCt or Pfaffl methods, and interpreting results with appropriate statistics. Following these steps ensures accurate, defensible qPCR data for bioscience research.
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…
