NCI-H292 In Vitro Cell Exclusion Zone Assay (Migration)

This assay is to provide NCI-H292-based In Vitro Cell Exclusion Zone Assay (Migration) to accelerate our client's oncology projects. The assay will be customized according to the specific requirements. Please contact our scientists to discuss more details.

NCI-H292

Human

This line was derived from a lymph node metastasis of a pulmonary mucoepidermoid carcinoma. The cells were isolated in a chemically defined medium (HITES) and later adapted to growth in media supplemented with serum.

In Vitro Cell Exclusion Zone Assay (Migration)

For the cell exclusion assay, before seeding of cells in well plates, silicon stoppers (for 96- or 384-well formats) are placed inside the wells to create a cell free zone. Once cells attain confluency, stoppers are removed, allowing cells to cover the exclusion zone. Unlike in the normal scratch assay, sharp and uniform borders can be created with the stoppers. When placing a stopper inside wells, stopper must be firmly attached to the bottom of the well plate to prevent movement of cells beneath the stopper. Cells moving towards the exclusion area can be monitored using light or fluorescence microscopy.

Cell Migration and Invasion Assays

The movement of cancer cells and formation of tumors in neighboring tissue is a sequential cascade known as invasion-metastatic cascade, which includes cancer cell invasion through extracellular matrix (ECM), intravasation into blood and colonization at sites after they exit from blood circulation. Migration and invasion are two dif ferent processes where, cell migration involves movement of cells without passing through a barrier such as ECM, whereas cell invasion involves passing through a barrier such as ECM while destroying it.
