Overview | Also available: Cell Comb™ Scratch Assay! Get biochemical data from a scratch assay! Click Here Introduction Cell migration is a fundamental function of normal cellular processes, including embryonic development, angiogenesis, wound healing, immune response, and inflammation. Microporous membrane inserts are widely used for cell migration and invasion assays. The most widely accepted of which is the Boyden Chamber assay. Recently, a fluorescence blocking membrane insert was introduced to address these issues; however, this approach requires labeling of the cells with Calcein-AM and extensive washing to remove free Calcein before cell migration. The effect of this treatment on cell behavior/migration remains questionable. The CHEMICON® QCM™ 24-well Cell Migration Assay (ECM508) eliminates cell pre-labeling and manual counting. The 24-well insert and colorimetric detection format allows for quantitative comparison of multiple samples. In the CHEMICON® QCM™ 24-well Migration Assay, cells that have migrated to the bottom of the insert membrane are stained. The stain is then extracted and transferred to a 96-well microtiter plate for colorimetric measurement. The CHEMICON® QCM™ 24-well Migration Assay provides a quick and efficient system for quantitative determination of various factors on cell migration, including screening of pharmacological agents, evaluation of integrins or other adhesion receptors responsible for cell migration, or analysis of gene function in transfected cells. The CHEMICON® QCM™ 24-well Migration Assay utilizes an 8 mm pore size, as this is appropriate for most cell types. This pore size supports optimal migration for most epithelial and fibroblast cells; however, it is not appropriate for lymphocyte migration experiments. The system may be adapted to study different types of cell migration, including haptotaxis, random migration, chemokinesis, and chemotaxis. In addition, Chemicon continues to provide numerous migration, invasion, and adhesion products including: · QCM™ 8μm 96-well Chemotaxis Cell Migration Assay (ECM510) · QCM™ 5μm 96-well Chemotaxis Cell Migration Assay (ECM512) · QCM™ 3μm 96-well Chemotaxis Cell Migration Assay (ECM515) · QCM™ 96-well Cell Invasion Assay (ECM555) · QCM™ 96-well Collagen-based Cell Invasion Assay (ECM556) · 24-well Insert Cell Migration and Invasion Assay Systems · CytoMatrix™ Cell Adhesion strips (ECM protein coated) · QuantiMatrix™ ECM protein ELISA kits Test Principle The CHEMICON® QCM™ 24-well Cell Migration Assay is performed in a Migration Chamber, based on the Boyden chamber principle. Each kit contains 24 inserts; each insert utilizes an 8 mm pore size polycarbonate membrane, as this is appropriate for most cell types. This pore size supports optimal migration for most epithelial and fibroblast cells; however, it is not appropriate for lymphocyte migration experiments. Cells that have migrated through the polycarbonate membrane are incubated with Cell Stain Solution, then subsequently extracted and detected on a standard microplate reader (560 nm). The system may be adapted to study different types of cell migration, including haptotaxis, random migration, chemokinesis, and chemotaxis. |
Materials Required but Not Delivered | 1. Precision pipettes: sufficient for aliquoting cells. 2. Harvesting buffer: EDTA or trypsin cell detachment buffer. Suggested formulations include a) 2 mM EDTA/PBS, b) 0.05% trypsin in Hanks Balanced Salt Solution (HBSS) containing 25 mM HEPES, or other cell detachment formulations as optimized by individual investigators. Note: Trypsin cell detachment buffer maybe required for difficult cell lines. Allow sufficient time for cell receptor recovery. 3. Tissue culture growth medium appropriate for subject cells, such as DMEM containing 10% FBS. 4. Chemoattractants (eg. 10% FBS) or pharmacological agents for addition to culture medium, if screening is desired. 5. Quenching Medium: serum-free medium, such as DMEM, EMEM, or FBM (fibroblast basal media), containing 5% BSA. Note: Quenching Medium must contain divalent cations (Mg2+, Ca2+) sufficient for quenching EDTA in the harvesting buffer. 6. Sterile PBS or HBSS to wash cells. 7. Distilled water. 8. Low speed centrifuge and tubes for cell harvesting. 9. CO2 incubator appropriate for subject cells. 10. Hemocytometer or other means of counting cells. 11. Trypan blue or equivalent viability stain. 12. Microplate reader (560 nm). 13. 24-well tissue culture plate. 14. Sterile cell culture hood. |
