QCM Laminin Migration Assay (24-well, colorimetric)

Research Category
Cell Structure

The Millipore QCM Laminin Migration Assay incorporates a 5 μm porous membrane Boyden chamber and mouse laminin, a major extracellular matrix (ECM) protein in basement membrane, to examine cell migration dependent upon the presence of laminin. The laminin is isolated from mouse sarcoma and it is enriched with mouse laminin 1 (laminin-111). This ECM promotes cell adhesion, proliferation as well as migration in many cell types such as embryonic stem cells, neural cells, liver cells and cancer cells. Cells interact with laminin through integrins α1β1, α2β2, α3β1, α6β1, α7β1, and α6β4. The assay is designed specifically to examine the migration of a subset of fibroblasts, cancer cells and neural cells.
Laminin protein is coated on the bottom of each chamber′s porous membrane as the driver for cell migration. A similarly BSA-coated control chamber(s) provides an appropriate migration control. Cells that migrate toward laminin are stained using crystal violet, a nucleic dye, extracted from the membrane surface, and quantified on a microplate reader using spectrophotometry.

Each kit provides sufficient materials for the evaluation of 24 samples.

Cell migration is a fundamental function of normal cellular processes, including embryonic development, angiogenesis, wound healing, immune response, and inflammation.
Cell migration may be evaluated using several different methods; the most widely accepted being the Boyden Chamber assay. The Boyden Chamber system uses a two-chamber plate model in which a porous membrane provides an interface between two chambers. Cells are seeded in the upper chamber and chemoattractants placed in the lower chamber. Cells in the upper chamber migrate toward the chemoattractants by passing through the porous membrane to the lower chamber. Migratory cells are stained and quantified. Most cells are sized from 30 to 50 μm can migrate through 3 to 10 μm pore.
