Cytotoxicity assay types
WebThe cell line typically used for cytotoxicity testing is the L929 mouse fibroblast cell. If appropriate for the end use of the product, other cell lines may be employed such as the rabbit cornea cells (SIRC) or embryonic lung cells (WI-38). There are three types of cytotoxicity tests: extract, direct contact and indirect contact. WebCytotoxicity assays, such as those that assess cell membrane integrity or measure the reducing potential of the cell, and even more complex assays like microarray analysis are relatively straightforward to perform and may accompany gene expression assays in the …
