摘要: The properties of Sf9 and Tn5 insect cells were analyzed comparatively under serum-free culture conditions. in SF900II medium apparently utilized sucrose as a primary nutrient both before after virus infection, yielding small amounts lactate ammonia. Excell 401 consumed all the nutrients examined, including sucrose. productivity recombinant glycoprotein, OSF-2, by cells, was moderate monolayer spinner cultures, but ability to secrete it compromised former case. Relative produced 30-fold more OSF-2 either mode. (c) 1996 John Wiley & Sons, Inc.
