WebBy far the most common way to detach cells is via trypsinization. Trypsin is a cheap proteolytic enzyme, usually extracted from the pancreas of pigs (porcine trypsin), and has been used successfully for various applications. Also, it can be inactivated by serum, which is very convenient for cell culture.
WebJun 12, 2008 · The first step in subculturing is to detach cells from the surface of the primary culture vessel by trypsinization or mechanical means. The resultant cell suspension is then subdivided, or reseeded, into fresh cultures.
