2 Filter-sterilize (0.2 µm) and keep no longer than 4 weeks. Store at room temperature to facilitate detection of contamination. | |||||
3 Prepare a 25 cm2 flask and seed cells according to standard protocols (see DSMZ catalogue for ACC 2 and ACC 57). Incubate at 37°C plus 5% CO2. When a confluent layer has formed, infection can be carried out. | |||||
4 Exchange medium with 6 ml of Infection Medium (as above with the addition of 1 µg/ml cycloheximide (final concentration)) and add 500 - 1000 µl of EB stock solution (thawed quickly to 37°C). | |||||
5 Centrifuge for 1 h onto the cell layer at 1600 rpm at 20°C. | |||||
6 Incubate at 37°C + 5% CO2. Control cells daily and look for inclusions. Not all Chlamydiae form well-visible inclusions, ultimately, immunofluorescence or in situ-hybridization techniques are necessary to visualize inclusions. |
