Category: Cell Biology and Cell Culture: Apoptosis Protocols: Apoptosis Analysis

Analysis of DNA Fragmentation Using the JAM Assay. By Shailaja Kasibhatla et al., The JAM assay is based on labeling nuclear DNA of cycling cells with [3H]thymidine and harvesting samples on glass fiber filters. Apoptosis will generate DNA fragments small enough to pass through the glass fiber filter, resulting in decreased radioactivity of the particular sample. Cell-mediated cytotoxicity or cell killing mediated by cytotoxic T lymphocytes (CTL) can also be measured by this technique. - [Read Analysis Of DNA Fragmentation Using The JAM Assay (Subscription Required)]

Category: Cell Culture Protocols: Cell Storing and Cell Freezing Protocols

Cryogenic preservation (storage below -100°C) of cell cultures is widely used to maintain backups or reserves of cells without the associated effort and expense of feeding and caring for them. The success of the freezing process depends on four critical areas: Proper handling and gentle harvesting of the cultures; Correct use of the cryoprotective agent; A controlled rate of freezing; Storage under proper cryogenic conditions. - [Read Cryogenic Preservation and Storage of Animal Cells Protocol]
