Cell migration assay using LBL-Dye CellTag 580 and LBL-Dye CellTag 717

A cell migration assay is a laboratory technique used to study how cells move in response to stimuli. It's crucial for understanding processes like tissue repair and cancer metastasis.

Common assays include:

  • the scratch/wound healing assay, where a gap is created and closure is monitored;
  • the transwell assay, where cells migrate through a porous membrane toward a chemoattractant;
  • time-lapse microscopy for dynamic analysis.

These assays help researchers explore factors influencing cell movement and are essential for various biological studies.

LBL-Dye CellTag 580 and LBL-Dye CellTag 717 are two Cellular Tracers particularly well-adapted for cell migration assays.

After 2 days of acquisition, cells continue to divide and move. We visualize the cellular movements and the mixture of cells that are carried out.

No phototoxicity, no photobleaching, and no dye passive transfer are visible for all acquisition time.

Live-time imaging of human epithelial cell line with wide field microscope (Celdiscoverer 7, Zeiss) with 20X objective. Image acquisition every 10 min during few hours (3 days for entire time acquisition). Cells are cultured in “Culture-Insert 2 Well in µ-Dish 35 mm” (Ibidi) for 24 hrs. LBL-Dye CellTag 580 (4 µg/ml, Cyan) and LBL-Dye CellTag 717 (2 µg/ml, Majenta) are incorporated in each well during 1 hr; the cells outside of the insert are not labeled. After 3 rinses, insert is removed, and cell contact is followed for 3 days. Time image interval: 10 min. Transmitted light; Exc 560, Em 592/25 for LBL-Dye CellTag 580; Exc 650, Em 709/100 for LBL-Dye CellTag 717.

Deep tissue imaging of cancer in the infrared

The efficacy of fluorescence-guided surgery in facilitating the real-time delineation of tumours depends on the optical contrast of tumour tissue over healthy tissue. Here we show that CJ215—a commercially available, renally cleared carbocyanine dye sensitive to apoptosis, and with an absorption and emission spectra suitable for near-infrared fluorescence imaging (wavelengths of 650–900 nm) and shortwave infrared (SWIR) fluorescence imaging (900–1,700 nm)—can facilitate fluorescence-guided tumour screening, tumour resection and the assessment of wound healing...
