CyTRAK Orange™ imaging with eGFP (example)

A novel orange fluorescing nuclear/cytoplasm dye for live cells ....

CyTRAK Orange™ allows the direct segmentation of HCS images in LIVE cells

CyTRAK Orange™ has excellent compatibility with eGFP:

  1. Single step addition of probe to get labelling of nucleus (and cytoplasm)
  2. Simultaneous two channel emission, single excitation wavelength (488nm) is optimal for both probes
  • Only one laser required
  • Only single well-visit required to capture dual channel image
  • Single illumination source (one laser line) avoiding instrument alignment
  • Chromatic error or co-alignment of signal is not dependent on the excitation
  • Pixel-pixel registration of channels is excitation independent
  • Simpler instrument set-up enhancing the cross-compatibility of CyTRAK Orange™

The following workflow is an example of the image processing steps used with CyTRAK Orange™ and eGFP.

EXAMPLE

Live cells labeled with CyTRAK Orange™ (20 μM) for 20 minutes at 37ºC, no wash. Images captured using confocal microscopy 488 nm simultaneously (or can be termed as single excitation); (i) CyTRAK Orange™ channel: 598/40 nm (ii) GFP-cyclin B1 channel: 522/35 nm
