TAXIScan is ECI's unique technology to form chemoattractant concentration gradient in a small space so as to observe cellular chemotaxis movement with good repeatability. Existing model of EZ-TAXIScan with a mere 10X objective lens, limited conventional bright-field observation and up to 6 sample simultaneous assays is appreciated well for its easy use of TAXIScan functions.
Newly introduced TAXIScan-FL　makes fluorescent observation possible. The equipment is mounted with up to 40X objective lens and bright field observation system with the use of differential interferometry. The number of simultaneous assay samples is increased up to 12 so that higher analysis with enhanced throughput can be anticipated.

• The equipment enables fluorescent observation for various types of cell performing chemotaxis movement. Mounted with high-power objective lens (up to 40X）and differential interferometry optical system enable clear image acquisition at bright field observation. The employment of autofocus mechanism also enables stable focus for extended period to time.

  

• Simultaneous observation of transient increase (in fluorescent strength) of intracellular calcium concentration and chemotaxis movement were performed using cells stained with fluorescent calcium indicator (Fluo-3) (cell: human monocyte, chemoattractant: hMIP-1a)

  

• EZ-TAXIScan made observation of degranulation phenomena in mast cell possible. In contrast, TAXIScan-FL enables bright field observation in much higher magnification and differencial interferometry. By doing fluorescent straining for mast cells (blue : nucleus, green : calcium concentration, orange : degranulation), it becomes possible to observe transient calcium concentration increase in each cell before degranulation, etc. more in detail.
