Fam Caspase 8 and 9 Binding Assay for Embryos Protocol The FAM caspase binding assay kits from ATCC Corporation can be used to determine amounts of active caspases in cells. The FAM-labeled caspase inhibitor can freely diffuse into the cell. Active caspase irreversibly binds the inhibitor. Upon washing the cells, the amount of fluorescence is proportional to the amount of active caspase in the cell. FAM-LETD-fmk (catalog no. 30-1306) is used to detect caspase 8 and FAM-LEHD-fmk (catalog no. 30-1308) is used for caspase 9.
Mini-Chamber for Regulating Gaseous Environment During Culture A simple and inexpensive chamber for regulating gaseous environment of small culture plates, such as those used for culture of preimplantation embryos, can be constructed using disposable media-filtration devises such as Corning’s 115-ml system. The following is a description of how to make such a device.
