Other Notes

Cultures from HPA Culture Collections and supplied by Sigma are for research purposes only. Enquiries regarding the commercial use of a cell line are referred to the depositor of the cell line. Some cell lines have additional special release conditions such as the requirement for a material transfer agreement to be completed by the potential recipient prior to the supply of the cell line. Please view the Terms & Conditions of Supply for more information.


From normal female embryonic lung (expect collagen production). These cells have a very broad human virus spectra. Particularly useful for the isolation of rhinovirus. Cells from multilatered membrane when incubated for long periods with periodic pH adjustments. Used in the preparation of human virus vaccines.

Subculture: Spit at 70-80% confluency, approx. 1:3 to 1:6, seed at 2-4x104 viable cells/cm2. Trypsinize using 0.25% solution, with or without EDTA, 37 °C and 5% CO2.
