Millicell μ-Migration Assay Kit
Traditional multiwell (Boyden chamber) migration assays can
have limitations, such as: (1) gradients are not linear, well-established, or
controlled, (2) quantification of migratory cells is based on an endpoint
measurement rather than a dynamic determination, and (3) imaging of the cells
while they are migrating is currently not possible.
The Millicell µ-
Migration Assay Kit overcomes these limitations.
Its microfluidic,
low-volume technology promotes a stable, diffusion-generated concentration
gradient that is consistently linear and lasts for more than 48 hours. Designed
for video microscopy assays, the µ-Migration Slide is made from a plastic with
high optical qualities similar to those of glass. At specific time intervals,
images of the observation area can be acquired, allowing real-time monitoring
and quantitative measurements of cell migration.
Benefits
- Live cell tracking of single cell
or cell population migration
- Establishes a stable and linear
concentration gradient that lasts ≥ 48 hours
- Helps distinguish
chemotaxis from random movement
- Allows for multiparametric analysis,
including cell directionality and velocity
- Enhanced optical imaging
of slow- and fast-migrating cells
- Analyze 3 chemoattractants in
parallel for increased throughput and flexibility
- No need to spend
time or money on optimization
- Ready to use, no assembly needed

A stable, linear concentration gradient
The
concentration profile remains linear over the 1 mm observation window after 1
hour and is linear and stable for over 48 hours.

**The calculated maximum concentration is only 70% of the applied concentration. The final maximum concentration is only 33% of the applied concentration. Compare this with a Boyden chamber where very steep gradients may form along a single axis perpendicular to the surface of the membrane.
Compatibility with multiple cell lines
HT-1080,
HUVEC, MDA-MB-231, and NIH-3T3 cell lines have been shown to work effectively
with the Millicell µ-migration kit.
