BioTek technologies: Augmented microscopy

BioTek’s instrumentation and software together create the unique Augmented Microscopy experience; the integration and automation of all steps from image capture to publication-ready data. There’s no need for other software – Gen5 does it all.

Quickly, and simply:

  • Images are automatically captured: end point, time-lapse, montage, z-stack
  • Automated processing, including background flattening and deconvolution, optimizes images for downstream analysis
  • Nuclear and cytoplasmic components are identified with primary and secondary masks
  • Image analysis offers qualitative and quantitative data
  • Annotation of single or sequential images is available on-screen, in real time
  • Video clips can be generated from time-lapse sequences with a single click

Augmented Microscopy creates a ‘map’ with key analytical information, helping you to make informed decisions faster.

Capture

With Gen5 software, images can be captured by a “manual” mode for lower throughput, typically imaging a few samples at a time. “Experiment” mode automates image capture and analysis in multiple wells and can include both imaging and plate reading, plus other steps required for some live cell applications, like reagent injection, shaking and incubation.  In both modes, the intuitive interface and automated functions like “find image”, Auto Exposure, Auto LED intensity, Autofocus (including image-based and laser autofocus) capturing images simple and efficient.  Live cell kinetic sequences can also be completely automated, from initial image capture through movie creation. Images captured in Gen5 are ready for automated processing an in-depth quantitative analysis.

Process

Image preprocessing, including background flattening and image smoothing, optimize images for downstream analysis. Image processing features in Gen5 include:

  • Image stitching, which allows multiple tiled images (montages) to be software aligned, creating a complete picture of the entire sample with great accuracy, to provide more meaningful data.
  • Z-projection, which is essential for 3D imaging applications like spheroid, tumoroid and hanging droplet assays whose biology can’t be captured adequately with an objective’s typical depth of field.
  • Digital phase contrast overcomes the meniscus effect often seen in 96- and 384-well plates during brightfield imaging. Digital phase contrast is an enhancement technique that minimizes uneven illumination and creates a more consistent contrast across the image for better visualization.

Analyze

Gen5 offers powerful image analysis for a broad range of live and fixed cell imaging. Automated cell counting, label-free cell counting, transfection efficiency and nuclear translocation analyses are facilitated with features like dual masks for nuclear and cytoplasmic measurements, dynamic thresholding and custom object-level metrics.

Publish

After image analysis, it’s common to annotate specific details in the image for publication or other documentation purposes. Gen5 has a built-in annotation tool, so there’s no need to export image files to another software package. Live cell kinetics can be captured and a .wmv or .mp4 file generated automatically right within Gen5. Still images can be exported in a variety of common formats.  These features make publication-ready images and data from Gen5 available with a few clicks.

Gen5 automatically generates video of time lapse images, like this from a label-free wound healing assay.
