WebFeb 7, 2024 · HEK contained 4-10-fold higher amounts of lyso phosphatidylethanolamine (LPE) and 2-4-fold higher amounts of lyso phosphatidylcholine (LPC) compared to SP2/0 and CHO cell lines. C18:1 followed by C16:1 were the main contributors to the difference in both LPE and LPC levels. WebOct 31, 2012 · Two frequently used mammalian cell lines are HEK and CHO. HEK is a cell line originally derived from Human Embryonic Kidney tissue. HEK cells are easy to grow and transfect, and transient transfection frequently gives good expression levels, which has made this cell line widely used in research.
