Cell Emigre


A quick & quantitative assay for determining linear cell migration rate.
It is designed for use with attachment-dependent mammalian cells.

What can Cell Émigré be used for?

  • Cell Émigré is designed to measure the linear migration rate of attachment-dependent mammalian cells.
  • Migration rate responses can be readily compared across different cell types. The assay provides a rapid means of evaluating and comparing the effect of chemical or biological treatments such as chemical agents, proteins, peptides, antibodies or genetically modified cells.

What are the advantages of Cell Émigré?


The end-user supplies a cell sample (of freshly detached cells in fluid suspension) to a microfluidic ‘chip’. The chip then automatically distributes cells to microchannel arrays – ready for attachment & migration. No pumps or external fluid connections are required; each chip contains a reservoir for culture medium which is filled during the initial cell addition step.


Existing 2D-migration assays often attempt to measure ‘random-walk’ cell migration – a challenging task! Cell Émigré takes the innovative approach of quantifying migration within an array of linear microchannels. Each cell under assay is constrained to a linear migration path through contact-guided migration along a microchannel wall.


Cells begin migrating within Cell Émigré aligned to a common START position; a cells displacement from this position indicates its linear migration distance. There is no need for video recording or computer image analysis.

Each microchannel in the array contains a parallel measurement scale calibrated in microns. Cell migration can be rapidly & easily quantified (to the nearest 50μm) by visually comparing the alignment of a cell within the microchannel with this integrated measurement scale (using x40-x100 microscopic examination). Migration can be quantified at any time point during an assay.

Results may be expressed as a migration rate: microns per hour (μm/h).


Achieved through the use of microfluidic technology. A single chip containing 3x assays consumes <350μl of fluid when loaded. This reduces costs in terms of cells and reagents.

Coated Slides (Epoxysilane, Aldehydesilane, Aminosilane, or Hydrogel Coating)


Nexterion® Slide E is especially suitable for covalent immobilization of amino-modified and unmodified Oligonucleotides. The epoxy surface coating allows efficient and stable attachment of the biomolecules and provides optimal probe presentation. The nucleic acids react instantly with the epoxy modified surface to form a stable covalent bond. The density of epoxy-groups of the surface remains constant over the entire surface of the slide and has been adjusted to provide optimal binding capacity. The hydrophobic surface creates smaller spot diameters ideally suited for high-density arrays. The surface chemistry is stable and remains active even during very long spotting runs.

Recommended Probe Types:

  • Amino-modified and unmodified oligonucleotides
  • cDNA molecules and PCR products


  • Stable and covalent binding of probes
  • Superior signal-to-background ratios even from weakly expressed genes
  • Hydrophobic coating supports the spotting of high-density arrays
  • Epoxy chemistry enables long spotting runs

A full range of functional coating chemistries for DNA and protein microarraying is available. Please contact our Product Specialist for your specific microarray application needs.

Fetal Bovine sera


US Origin Fetal Bovine Serum (FBS) is the most widely used FBS in the world. Although US Origin FBS is considered the world’s standard for quality it is never the less becoming a lower standard in the view of the OIE (World Organization for Animal Health) and other regulatory bodies. On a scale of 1-4 for geographical BSE risk (GBR), with 1 being the lowest risk and 4 being the highest risk, US FBS ranks a 3 – demonstrating a moderate to high risk that BSE exists in the USA. US Origin FBS provided by J R Scientific is of the highest quality available in the USA. It is collected using state of the art aseptic collection techniques resulting in low endotoxin and hemoglobin concentrations.
