[Screen of media for insect cells (HzAm1) growth and its adaptation to low serum culture].

Insect cell-baculovirus system is a useful tool for both insecticidal virus production and the expression of medically useful foreign genes. Serum-free culture or low serum culture for insect cells is essential and significant. Media for the growth of insect cells HzAm1 from three kinds of commercial media TC-100,GRACE and IPL-41 with 10% serum were investigated and screened. The result shows that medium TC-100 is the most suitable medium for the growth of cells HzAm1. Adaptation of insect cells HzAm1 to cultures in medium TC-100 with serum reduction from 10% to 1% was carried out as cultures were supplemented with lactalbumin hydrolysate and yeastolate etc. Growth of insect cells HzAml in medium TC-100 with serum 1%, lactalbumin hydrolysate and yeastolate was well.
