The VAST FluoroImager automates positioning of 2-7 dpf zebrafish larvae. The larvae are oriented accurately and reproducibly within a glass capillary using a set of rotational motors. Included with the VAST FluoroImager:

  • Ability to load, position, and rotate a larva to a user selected orientation
  • On-board 10µm resolution camera captures precise images
  • 360° imaging consisting of brightfield and 1-3 fluorescent channels
    • Channel LEDs: 385nm (Violet), 470nm (Blue), 565nm (Green)
    • Channel filters: 445nm, 512nm, 615nm
  • Ability to generate Optical Projection Tomography (OPT) datasets with the VASTomography software
  • Cellular level imaging by mounting to an upright microscope
  • Seamless larva ejection and reloading from bulk reservoir

Capillary/fluorescence illumination module

Composed of the capillary unit of the VAST BioImager with the addition of the fluorescence module containing the LEDs and detectors for capturing fluorescence from the larvae.
