OverviewpdfSDSpdfProtocol


Our Cell Explorer™ fluorescence imaging kits are a set of tools for labeling cells for fluorescence microscopic investigations of cellular functions. The effective labeling of cells provides a powerful method for studying cellular events in a spatial and temporal context. This particular kit is designed to uniformly label live cells in red fluorescence for the studies that require the fluorescent tag molecules retained inside cells for relatively longer time. The kit uses a weakly fluorescent dye that carries a cell-retaining moiety. The dye becomes strongly fluorescent upon entering into live cells, and trapped inside live cells to give a stable fluorescence signal for relatively long time. The dye is a hydrophobic compound that easily permeates intact live cells. The labeling process is robust, requiring minimal hands-on time. It can be readily adapted for a wide variety of fluorescence platforms such as microplate assays, immunocytochemistry and flow cytometry. It is useful for a variety of studies, including cell adhesion, chemotaxis, multidrug resistance, cell viability, apoptosis and cytotoxicity. The kit provides all the essential components with an optimized cell-labeling protocol.

Protocol summary

  1. Prepare samples
  2. Add 10X Track It™ Red working solution (10 µL/well)
  3. Incubate the cells at 37°C for 15 to 60 minutes
  4. Wash the cells
  5. Examine the specimen under fluorescence microscope with Texas Red filter or flow cytometer with 610/20 nm filter (PE-Texas Red channel)

Important notes
Thaw all the components at room temperature. Centrifuge the Component A brieftly before opening.

PREPARATION OF WORKING SOLUTION

Dilute 500X Track It™ Red DMSO stock solution (Component A) into Assay Buffer (Component B) to make a 10 to 25X Track It™ Red working solution. The working solution should be prepared enough for all the wells at 10 μL/well with the appropriate concentration. For example, to get a 10X final concentration of Track It™ Red for one 96-well microplate, dilute 20 μL of 500X Track It™ Red DMSO stock solution into 1 mL of Assay Buffer (Component B) to make 1 mL of 10X Track It™ Red working solution. Note: The final concentration of the Track It™ Red working solution should be empirically determined for different cell types and/or experimental conditions. It is recommended to test at the concentrations that are at least over a ten fold range.

SAMPLE EXPERIMENTAL PROTOCOL

  1.  Add 10X Track It™ Red working solution to the cell wells which should be equal to 1/10 of the volume of cell culture medium. For example, for a 96-well plate, add 10 µL/well of 10X Track It™ Blue working solution into the cells.

  2. Incubate the cells in a 37°C, 5% CO2 incubator for 15 to 60 minutes.

  3. Wash cells with Hanks and 20 mM Hepes buffer (HHBS) or an appropriate buffer.

  4. Fill the cell wells with growth medium.

  5. Analyze the cells using a fluorescence microscope with Texas Red filter or flow cytometer with 610/20 nm filter (PE-Texas Red channel).
