An alternative to culture-based cell death detection is an assessment of other cell viability indicators using fluorescent dyes, including membrane potential and membrane integrity. Live/Dead assays differentiates live and dead cells using membrane integrity as a proxy for cell viability and are based on a fluorescent staining procedure followed by detection using flow cytometry. However, samples preparation for such flow cytometry-based techniques could be challenging. Cell harvesting by trypsinization, mechanical or enzymatic cell disaggregation from tissues, extensive centrifugation steps, may all lead to preferential loss of apoptotic cells. To overcome this strictly follow manufacturers instruction of the detection kit.

Cell Invasion or Cell Migration assays are technically challenging to set up as the gradient between the two compartments equilibrates in time during the assay. It is also problematic to view cells and for cells to migrate through a non-physiologic polycarbonate or polypropylene filter. Care must be taken while loading the well with cells to form a single cell suspension. Precaution must be taken while trypsinization (under-trypsinization can lead to cell clumping while over-trypsinization could strip off adhesion molecules necessary for migration). This leads to difficulty in getting significant results, when only small numbers of cells cross the filter or when the distribution and/or staining of the cells is uneven.
