Abstract
Summary
HeLa cells and chick embryo fibroblasts were grown on glass and harvested under various conditions. Trypsinization and scraping were each compared with alcoholether denaturation. Trypsinization was found to be less efficient as a means of obtaining material for chemical analysis although less damaging to cell viability than scraping. Alcohol-ether denaturation in situ was the preferred means of harvesting cells for chemical analysis.
