Superior Growth and Reproducibility
Expression Systems’ ESF 921TM Insect Cell Culture Medium is designed for maximum expression for applications such as; gene therapy drug substance, virus-like particles, virus vectors and proteins of interest. ESF 921TM is widely recognized as the industry standard for the baculovirus and insect host cell system.The line graph presents reproducible growth curves for Sf9 cell cultures in nine different lots of ESF 921TM medium manufactured over a period of 12 months.
Sf9 cells from a mid-log phase culture were seeded into *9 different lots of ESF 921TM at a density of 0.75×106/ml. Cultures were sampled daily to determine viable cell count.
